Yes, absolutely. Our at-home test kits meet the highest standards of laboratory testing:

CLIA/CAP Accredited: We partner with a laboratory that holds both Clinical Laboratory Improvement Amendments (CLIA) certification and College of American Pathologists (CAP) accreditation. These are the gold standards in laboratory testing.

Rigorous Validation: Each assay undergoes extensive validation to meet and exceed federal CLIA requirements. This ensures accuracy and reliability comparable to traditional lab tests.

Quality Assurance: Our lab employs strict quality control measures to guarantee consistent and accurate results.

FDA-Registered Components: All components of our test kits are registered with the FDA, ensuring safety and efficacy.

Expert Analysis: Your results go through the standard analysis required by CLIA and overseen by medical experts, then we personalize your results with additional insights and recommendations for optimal health.

With SiPhox, you're getting the convenience of at-home testing without compromising on the quality and accuracy you'd expect from a traditional laboratory setting.

We exclusively work with CLIA/CAP accredited labs that perform extensive validation on each assay to meet federal CLIA requirements. All our tests have a 95%-99% correlation coefficient when compared with standard venous blood draw results.

We independently perform in house testing against Labcorp and Quest on a quarterly basis to monitor and ensure our lab partners are meeting these standards.

We currently have the ability to support over 300 devices across ten categories. The most common devices our users connect are Apple Watch, Fitbit, Oura, EightSleep, Whoop, and Freestyle Libre.

When your report is ready for viewing, you will receive an email letting you know your user portal has been updated. You can access your report at any time by logging in and scrolling down to "Your Reports".


1. Our approach integrates up to 50 biomarkers into a single sample collection, optimizing the amount of data extracted from a single kit. This contrasts with other companies, which offer only 2-4 markers per kit, aiming to increase profits.

2. Our model enables us to provide test kits at cost, with the strategy to boost demand and subsequently lower production expenses.

3. Our organization specializes in developing blood testing hardware, with the ambition to enable instant at-home testing of all these markers at a cost significantly lower than current standards, without compromising the quality or accuracy of our tests.

Receive 17 base + 7 hormonal biomarkers (8 for males) to assess athletic performance, energy, mood, fertility, sexual health, and more.


Hormone+ expands your panel for a deeper understanding of your hormonal health, energy, mood, fertility, and reproductive health. This advanced test covers crucial hormone biomarkers, providing insights to help you optimize performance, manage health risks, and achieve your wellness goals.

For Males - 8 Additional Biomarkers Included:

 Estradiol, LH, SHBG, Prolactin, FSH, PSA, Albumin, Free Testosterone.

Unlock deeper insights into your hormonal health:

While our Core panel provides a strong overview of crucial health areas, the Hormone+ Panel goes deeper, revealing detailed information about hormones that govern your energy, mood, fertility, reproductive health, and potential risks.

Hormones like free testosterone (♂), estradiol (♀), and DHEA-S (♀) directly influence energy levels, muscle strength, and sex drive. Understanding how these hormones work more fully in your body allows you to make informed choices to support your health and fitness goals.

Understand fertility and reproductive health:

If you're planning a family or are interested in your reproductive health, the Hormone+ Panel is invaluable. It includes biomarkers like FSH, LH, and AMH (♀), which comprehensively look at your fertility status.

For men, the Hormone+ Panel includes PSA, a prostate cancer screening marker, and Free Testosterone, which is the bioavailable form of testosterone. Monitoring these values enables proactive management of potential health risks.

Additional Benefits of Vitamin B12 & Folate:

Hormone+ also checks Vitamin B12 and Folate, which are critical for energy production, nerve function, and mood regulation. Deficiencies in these nutrients can compound the symptoms of hormonal imbalance.

The Hormone+ Panel gives you a broader understanding of your body, enabling you to make better-informed decisions for optimal health and well-being.

Receive 17 base + 3 thyroid biomarkers that play a critical role in regulating metabolism, energy levels, and overall hormonal balance.

Thyroid+ expands your panel by going beyond TSH to uncover hidden thyroid issues, understand the root causes of fatigue, weight changes, and other symptoms so you can work proactively to optimize thyroid function and overall wellness.

Although our Core panel includes TSH, a primary thyroid screening tool, the Thyroid+ Panel provides a comprehensive picture with TPOAb, Free T3, and Free T4, revealing potential autoimmune issues and assessing the active forms of thyroid hormones.

TSH alone won't always detect thyroid dysfunction. Adding TPOAb (for autoimmune thyroid conditions), Free T3 and Free T4 shed light on the underlying causes of fatigue, weight changes, mood issues, and other symptoms often attributed to thyroid imbalances.

If you are already diagnosed with a thyroid condition, the Thyroid+ Panel offers valuable information for working with your doctor to understand how well your thyroid functions.

Thyroid health significantly impacts energy, metabolism, weight, mood, and long-term wellness. The deeper insights offered by the Thyroid+ Panel empower you to address potential imbalances alongside your healthcare provider proactively.

Understanding the complexities of your thyroid gland through these advanced biomarkers gives you a clearer picture of your overall health and how to take the best care of your body.
