Best Blood Biomarker Tests of 2025 Researched & Ranked

After spending 40+ hours researching blood testing services, interviewing medical experts, and analyzing hundreds of verified user reviews, we've come to a sobering conclusion: most at-home blood tests aren't worth your money.

That's not because the technology doesn't work. It's because most companies are selling you overpriced panels full of biomarkers you don't need, wrapped in fancy packaging with vague "wellness" promises.

But a few companies are actually delivering value—combining legitimate testing with useful insights and appropriate medical oversight. We're here to sniff out the best options and tell you exactly which ones deserve your hard-earned cash.

How We Rate Blood Testing Services

We use two distinct ratings to evaluate blood testing services:

🐾 Paw Prints (1-5): Our overall value rating based on user experience, price-to-value ratio, and whether the service actually delivers useful insights. Five paw prints means exceptional value; one means you should keep your wallet firmly closed.

🩺 Clinical Credibility (1-5): Our assessment of scientific validity, including lab certifications, testing methodology, medical oversight, and whether the results are actually meaningful. Five stethoscopes means gold-standard clinical validity; one means questionable science that should make your BS detector howl.

TL;DR: Just Tell Me What to Buy

Comprehensive Comparison Table

Individual Reviews: The Good, Bad & Ugly

Function Health: Data Overload (In A Good Way)

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺🩺🩺 (5/5)

The Basics:

• Price: $499/year for annual comprehensive testing (100+ biomarkers)
• Collection Method: Venous blood draw at Quest Diagnostics (20+ vials)
• Doctor Involvement: Clinician-written summaries with AI-assisted interpretation
• Turnaround: Approximately 2 weeks

What We Dig:

Function Health is the data nerd's dream—testing over 100 biomarkers across 20+ categories including hormones, metabolic markers, inflammation, organ function, vitamins, minerals, and even heavy metals. Their clinician summaries actually explain what's going on in plain English, and they've nailed the interface for tracking changes over time.

When we say comprehensive, we mean it. Function tests things other services don't even mention, like apolipoprotein subtypes, advanced inflammatory markers, and hormone metabolites. For people with mysterious symptoms or those who want the most complete health snapshot possible, there's nothing else this thorough.

What Makes Us Growl:

Let's address the elephant in the room: $499 is a lot of money. You're also looking at sitting through a substantial blood draw—20+ vials is no joke. Some

users report feeling overwhelmed by the sheer volume of data, and the company offers limited guidance on what to actually do about borderline or out-of-range results.

Unlike Hone or Blokes, there's no direct path to treatment if issues are identified. You'll need to take your results to your own doctor, who may or may not know what to do with all those exotic biomarkers.

Real User Experience:

"The amount of data was staggering," reported one verified user. "I discovered vitamin deficiencies my regular doctor missed for years, but I had to do my own research to figure out what some markers meant."

Bottom Line:

Function Health earns 4 Paw Prints for delivering the most comprehensive testing we've found, with excellent clinical credibility. But it loses a print for the high price and occasional data overload. It's perfect for the health-obsessed data lover, but overkill for most people with specific concerns.

Who Should Choose Function Health:

• People seeking the most comprehensive health assessment possible
• Those with mysterious symptoms that haven't been diagnosed elsewhere
• Health optimizers who want to track dozens of biomarkers
• Data-driven individuals who don't mind doing some of their own research

Alternatives to Consider:

SiPhox Health offers about half the biomarkers at a quarter of the price, making it a solid budget alternative.

Blokes: Men's Health Optimization Specialists

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺🩺 (4/5)

The Basics:

• Price: One-time tests from $149 (45 markers) to $699 (74 markers)
• Collection Method: Venous draw at lab; mobile phlebotomist (+$99) in select areas
• Doctor Involvement: Board-certified clinician review, 1:1 coaching, personalized plans
• Turnaround: 1-2 weeks

What We Dig:

Blokes doesn't mess around—they focus specifically on men's hormone optimization with a depth that generalist services can't match. Their clinicians actually understand the nuances of testosterone fluctuations, SHBG binding issues, and estrogen conversion. This isn't wellness fluff; it's serious hormone medicine.

Their "Optimization Score" approach gives you a clear picture of where your hormones stand relative to optimal (not just "normal") ranges, and their follow-up actually includes practical treatment plans. For men struggling with fatigue, sexual health issues, or body composition concerns, Blokes delivers the most comprehensive hormone assessment we've seen.

What Makes Us Growl:

The branding occasionally veers into "alpha male" territory, which might turn off some users. Their testing isn't cheap, especially if you opt for their Comprehensive Panel. The focus on hormone optimization means they sometimes push hormone therapies when lifestyle changes might help first.

Their at-home testing option is limited to certain states, meaning most users need to visit a lab or pay extra for mobile phlebotomy.

Real User Experience:

"My primary care doctor said my testosterone was 'normal' at 320 ng/dL. Blokes explained why that's actually low for my age and gave me practical options," one verified customer reported.

Bottom Line:

Blokes earns 4 Paw Prints for their specialized expertise in men's hormones and excellent physician support. They lose a print for the premium pricing and occasional heavy emphasis on hormone therapies. For men specifically concerned about hormone optimization, they're the clear leader.

‍Take a closer look at Blokes here

Who Should Choose Blokes:

• Men experiencing potential symptoms of hormone imbalance
• Those seeking TRT or other hormone optimization therapies
• Men over 40 concerned about age-related hormone decline
• Anyone who wants physician guidance along with testing

Alternatives to Consider:

Hone Health offers a similar men's hormone focus with a subscription model that may be more cost-effective for ongoing monitoring.

Hone Health: Continuous Optimization with Doctor Support

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺🩺 (4/5)

‍

The Basics:

• Price: $149/month (Premium) or one-time test + consult for $60
• Collection Method: At-home finger-prick or lab draw options
• Doctor Involvement: 30-45 minute physician consultations with treatment planning
• Turnaround: 2-3 weeks from test to results

What We Dig:

Hone wraps everything into one convenient package—testing, physician consultation, and treatment delivery. Their doctors spend a legitimate 30-45 minutes reviewing your case, not the rushed 5-minute telehealth norm. For ongoing monitoring, their quarterly testing helps you track how interventions are working over time.

Their marketing emphasizes "longevity," but what they actually deliver is solid hormone and metabolic health optimization with medical oversight. The $60 initial test offer makes it easy to try without a huge commitment, and their at-home testing is genuinely user-friendly.

What Makes Us Growl:

The subscription model isn't cheap at $149/month (plus medication costs), and their biomarker panel, while solid, isn't as comprehensive as Function or Blokes. Some users report occasional platform glitches and customer service delays.

Their finger-prick testing method for hormones raises some accuracy concerns, particularly for testosterone (more on this in our collection method section). They sometimes push supplements with limited evidence behind them.

Real User Experience:

"The doctor actually listened and explained everything clearly," one verified user said. "But be prepared for a sales pitch on their subscription during the consultation."

Bottom Line:

Hone Health earns 4 Paw Prints for their excellent physician consultations and convenient all-in-one approach. They lose a print for the expensive subscription model and more limited testing panel. They're ideal for people who want ongoing optimization with professional guidance.

‍Who Should Choose Hone Health:

• Those who want both testing and treatment in one service
• People who value physician guidance for interpreting results
• Men seeking hormone optimization with medical oversight
• Those who prefer at-home testing convenience

Alternatives to Consider:

Blokes offers more comprehensive hormone panels with similar physician support but without the subscription requirement.

LetsGetChecked: Targeted Testing Without Commitment

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺🩺 (4/5)

‍

‍

The Basics:

• Price: $89-$199 per test kit, no subscription required
• Collection Method: Finger-prick blood collection
• Doctor Involvement: Free nurse consultation for abnormal results; $49 for doctor telehealth
• Turnaround: 2-5 business days after lab receipt

What We Dig:

LetsGetChecked has built a reputation for reliability that's backed by over 17,000 positive reviews. Their à la carte approach lets you test exactly what you need without paying for irrelevant markers. With clearly written instructions and fast turnaround times, they've nailed the user experience better than most competitors.

Their nurse follow-up for abnormal results is a genuinely useful service that most competitors charge extra for, and their CLIA-certified lab testing maintains high quality standards. For specific health concerns like thyroid function or sexual health, their targeted panels make perfect sense.

What Makes Us Growl:

The modular approach means comprehensive testing gets expensive quickly—testing hormones, vitamins, and metabolic health would require three separate kits totaling over $400. Their finger-prick collection method has accuracy limitations for certain hormones (particularly free testosterone calculations).

Doctor consults cost extra ($49), and their treatment options are limited compared to Hone or Blokes. Some users report occasional shipping delays.

Real User Experience:

"The process was seamless," one verified user reported. "My results came back in 3 days, and when one marker was high, a nurse called me the same day to explain what it meant."

Bottom Line:

LetsGetChecked earns 4 Paw Prints for their excellent user experience, established reliability, and no-commitment approach. They lose a print for the potentially high cumulative cost of comprehensive testing. They're perfect for targeted concerns or first-time testers.

Who Should Choose LetsGetChecked:

• Those with specific health concerns who don't need comprehensive panels
• People who prefer no subscription commitment
• First-time testers who want a straightforward experience
• Those who value quick turnaround times

Alternatives to Consider:

Everlywell offers a similar à la carte approach but with a slightly different test menu and telehealth integration.

SiPhox Health: Comprehensive Testing Without Breaking the Bank

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺 (3/5)

‍

‍The Basics:

• Price: $119-$125 per comprehensive panel
• Collection Method: At-home finger-prick
• Doctor Involvement: Automated insights and coaching sessions; no direct MD consult
• Turnaround: 3-7 days

What We Dig:

SiPhox delivers the best value proposition we've found—approximately 50 biomarkers for about $125. That's half the price of most competitors for comparable testing breadth. Their modern interface makes understanding results straightforward, and they offer sensible lifestyle recommendations based on your data.

Their integration with wearable devices adds useful context to blood biomarkers, and their panel composition is thoughtfully designed to cover the markers most relevant to everyday health. For regular monitoring on a budget, they're unbeatable.

What Makes Us Growl:

The finger-prick collection method raises accuracy concerns for certain markers, particularly hormones. Without physician consultation included, you're largely on your own for interpreting borderline results or developing treatment plans.

As a newer company, they have fewer customer reviews to evaluate, and some users report occasional delays in receiving their test kits. Their coaching is more general than the personalized guidance from physician-led services.

Real User Experience:

"I was shocked at how comprehensive the testing was for the price," one early user reported. "The interface was intuitive, but I did end up taking the results to my doctor for further guidance."

Bottom Line:

SiPhox Health earns 4 Paw Prints for delivering exceptional value at a budget-friendly price point. They lose a print for the limited physician support and potential accuracy limitations of finger-prick testing. They're ideal for cost-conscious comprehensive testing.

Who Should Choose SiPhox Health:

• Budget-conscious testers who still want comprehensive data
• Those who prefer at-home testing convenience
• People who use wearable devices and want integrated analysis
• Self-directed researchers who don't need physician guidance

Alternatives to Consider:

Function Health offers more comprehensive testing with stronger clinical oversight, but at 4x the price.

InsideTracker: Data Integration for the Fitness Obsessed

Paw Prints: 🐾🐾🐾 (3/5)
Clinical Credibility: 🩺🩺🩺🩺 (4/5)

The Basics:

• Price: $299-$649 per test
• Collection Method: Venous blood draw at lab
• Doctor Involvement: None; algorithmic analysis and AI recommendations
• Turnaround: 5-10 days

What We Dig:

InsideTracker excels at connecting the dots between different data sources—blood biomarkers, DNA, and wearable device metrics. Their scientific foundation is solid, with clear explanations of what each biomarker means for your health. For athletes and fitness enthusiasts, their performance-focused approach offers relevant insights.

Their visualization tools make tracking changes over time intuitive, and the optional DNA testing adds useful context about genetic predispositions. The fact that they use venous blood draws ensures greater accuracy for hormone measurements.

The price is steep for what you get—up to $649 for their Ultimate package covering 48 biomarkers (less than half what Function tests at a similar price point). There's no physician support included, leaving you to interpret results yourself or take them to your own doctor.

Their algorithmic recommendations often feel generic ("eat more leafy greens"), lacking the personalization that physician-guided services provide. Some users report that the wearable integration, while innovative, doesn't always translate to actionable insights.

Real User Experience:

"The data visualization is beautiful," one verified user noted, "but I found myself wondering 'so what?' after reading many of the recommendations."

Bottom Line:

InsideTracker earns 3 Paw Prints for their innovative data integration and solid scientific foundation. They lose points for high pricing relative to biomarker count and limited personalization in recommendations. They're best suited for data-driven fitness enthusiasts.

Who Should Choose InsideTracker:

• Athletes and fitness enthusiasts tracking performance biomarkers
• Those who use wearables and want integrated analysis
• People interested in genetic insights alongside blood testing
• Self-directed optimizers who don't need physician guidance

The Basics:

• Price: $29-$249 per test kit
• Collection Method: At-home finger-prick or saliva
• Doctor Involvement: Optional telehealth through Everlywell+ subscription
• Turnaround: 3-5 business days

What We Dig:

Everlywell has made at-home testing mainstream, with wide availability and clear instructions. Their test options cover diverse health concerns, from food sensitivities to hormones to STIs. Their educational content is genuinely helpful, explaining biomarkers in accessible language with links to relevant research.

Their integration with telehealth services creates a pathway to treatment if issues are identified, and their established infrastructure means fewer delays than some newer competitors. For basic screening, they're a familiar option with decent reliability.

What Makes Us Growl:

Customer reviews paint a mixed picture—while many users have positive experiences, their 1.7/5 Trustpilot rating raises red flags about inconsistent service. Some users report lost samples, delayed results, or difficulty reaching customer support.

Their finger-prick testing method has the same accuracy limitations as other services using this approach, particularly for hormone testing. Their Women's Health test is priced at $249 for just 11 biomarkers, making it poor value compared to more comprehensive alternatives.

Real User Experience:

"Sample collection was straightforward," one user reported, "but it took three weeks and multiple emails to customer service before I got my results."

Bottom Line:

Everlywell earns 3 Paw Prints for their accessibility and educational content. They lose points for inconsistent customer service and questionable value on certain tests. They're best for basic screening or specific concerns where their specialized tests match your needs.

Who Should Choose Everlywell:

• Those seeking specific tests for targeted concerns
• People who value brand recognition and established infrastructure
• Those who might want telehealth integration for treatment
• First-time testers who prefer a widely used service

Blokes takes the top spot for men's hormone testing thanks to their specialized expertise, comprehensive hormone panels, and excellent physician support. Their understanding of the complex interplay between testosterone, estrogen, SHBG, and other hormones is unmatched among the services we reviewed. The fact that they can transition directly from testing to treatment makes them the clear choice for men seeking hormone optimization.

Runner-Up: Hone Health, which offers a more affordable entry point but slightly less comprehensive testing.

Best for Comprehensive Annual Testing: Function Health

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺🩺🩺 (5/5)

Nothing comes close to Function Health's 100+ biomarker panel for sheer comprehensiveness. Their venous blood collection ensures maximum accuracy, and their clinician-written summaries provide meaningful context for complex results. If you want the most complete picture of your health possible, Function Health is the undisputed leader.

Runner-Up: SiPhox Health, which offers about half the biomarkers at a quarter of the price.

Best Budget-Friendly Option: SiPhox Health

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺 (3/5)

Runner-Up: SiPhox Health, which offers subscription options at a lower price point but without physician guidance.

Best for Doctor Support & Treatment: Hone Health

Paw Prints: 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺🩺 (4/5)

With 30-45 minute physician consultations included, Hone Health provides the most comprehensive medical support among the services we reviewed. Their doctors don't just explain what your results mean—they develop personalized treatment plans and can prescribe medications or supplements as needed. This end-to-end approach earns them top marks for medical guidance.

Runner-Up: Blokes, which offers excellent physician support specifically focused on men's hormones.

The Bottom Line: Does At-Home Blood Testing Actually Work?

After diving deep into these services, we can confidently say: Yes, but with important caveats.

At-home blood testing has matured significantly, with legitimate laboratory analysis and meaningful insights now available without a doctor's visit. For specific concerns like hormone optimization or nutrient deficiencies, these services can provide valuable data that many primary care physicians don't routinely test.

However, not all services—or collection methods—are created equal. Here's what you need to know:

When At-Home Testing Is Worth It:

• You're monitoring specific biomarkers over time (hormones, lipids, etc.)
• Your doctor has dismissed concerns despite persistent symptoms
• You want a more comprehensive view than standard medical testing provides
• You're specifically interested in optimization, not just disease detection

When You Should Stick with Traditional Medical Testing:

• You have serious, acute symptoms that need immediate medical attention
• You need insurance to cover your testing
• You're testing biomarkers where finger-prick methods have poor accuracy
• You want guaranteed physician follow-up for abnormal results

Remember that while these services can provide valuable health insights, they don't replace comprehensive medical care. Always share concerning results with a qualified healthcare provider.

Collection Method Face-Off: Finger-Prick vs. Venous Draw

The biggest divide in blood testing services is how they collect your blood: finger-prick (capillary) or traditional venous draw. This isn't just about convenience—it affects accuracy.

Venous Blood Draw

Paw Prints (convenience/value): 🐾🐾 (2/5)
Clinical Credibility: 🩺🩺🩺🩺🩺 (5/5)

Pros:

• Gold-standard accuracy for most biomarkers
• Larger sample volume allows more comprehensive testing
• Better standardization and established protocols
• Essential for certain markers (complete blood counts, complex hormones)

Cons:

• Requires visit to lab or mobile phlebotomist
• More invasive and potentially uncomfortable
• Usually more expensive

Best For: Comprehensive hormone panels, metabolic testing, medical diagnostics

Finger-Prick Testing

Paw Prints (convenience/value): 🐾🐾🐾🐾 (4/5)
Clinical Credibility: 🩺🩺🩺 (3/5)

Pros:

• Convenient at-home collection
• Less invasive, minimal discomfort
• No appointment needed
• Often more affordable

Cons:

• Significant accuracy limitations for certain markers
• Higher sample failure rates (24% vs. 2.8% for venous)
• Increased hemolysis (red blood cell rupture) affecting results
• Limited sample volume restricts testing scope

Best For: Trend monitoring, basic wellness screening, regular testing of stable markers

The Scientific Reality Check

Scientific research shows that finger-prick testing has specific limitations worth understanding:

• Testosterone testing shows ~19% variance between finger-prick and venous samples—potentially the difference between "normal" and "low" results
• Hemolysis rates are significantly higher in finger-prick samples (23.7% vs. 3.1%), which can alter multiple biomarker measurements
• Certain markers simply can't be reliably measured with finger-prick methods, including some hormone metabolites and blood cell analyses

Here's Our No-BS Guidance:

Use finger-prick testing for:

• Initial screening when convenience is paramount
• Regular monitoring of stable, robust markers (cholesterol, HbA1c, vitamin D)
• Situations where trends matter more than absolute values

Insist on venous draw for:

• Comprehensive hormone testing, especially testosterone
• Diagnostic concerns requiring maximum accuracy
• Complete blood counts and cell analysis
• One-time testing where you need the most reliable results

The collection method matters more for some biomarkers than others. Check the accuracy breakdown below to guide your decision:

Transparency Statement

Health Hound may receive affiliate commissions if you purchase through links on our site. These commissions never influence our ratings or recommendations—if a service sucks, we'll tell you, regardless of potential revenue. We maintain strict editorial independence from all testing companies.

Final Word: Our Top Recommendation

After extensive research, if we had to choose just one blood testing service to recommend, it would be Function Health for comprehensive annual assessment or Hone Health for ongoing hormone optimization with treatment support.

However, the right choice depends entirely on your specific needs:

• Want the most comprehensive data? Function Health ($499/year)
• Looking for hormone optimization with doctor support? Blokes ($149-$699) or Hone ($149/month)
• Need the most affordable comprehensive option? SiPhox Health ($119-$125)
• Prefer targeted testing without subscription? LetsGetChecked ($89-$199 per test)

Remember that no blood test—no matter how comprehensive—can replace regular medical care. Use these services as a complement to, not a replacement for, appropriate healthcare.
