Quantify helps me keep my balance.
I can directly see how my diet, supplements, and lifestyle are affecting my hormone levels and sleep quality.

James Sinka YC Founder & Biohacker

Even as a doctor I find it cumbersome to access regular blood testing. Quantify allowed me to track my recovery from long COVID and optimize my vitamin D levels without taxing my busy schedule.

Jennifer Joe, MD Physician, CEO Vanguard.Health

Quantify has been valuable in letting me see the effects of high training volume on my hormones, specifically testosterone. I was in the dark on this during my last Ironman prep.

Stryker L Real Estate Broker & Ironman Athlete

With a long history of atherosclerosis in my family, I've always wondered how I can mitigate my own risk. With Quantify I can now intentionally track my cardiovascular risk for decades to come.

Colin Budries Army Officer & Longevity Enthusiast

Before my first Quantify test, I had no idea my hs-CRP or Cortisol levels were out of range. Now I have insights into how I can improve both and look forward to testing to see my improvements.

Alana Gonzales Biomedical Engineer & Rollerblader

At-home blood testing is the future of health and longevity optimization.

Michael Lustgarten, PhD Scientist II at USDA Jean Mayer Human Nutrition Research Center on Aging

Frequently Asked Questions

Is the Quantify blood test kit equivalent to standard labs?

Yes, we work with a CLIA/CAP accredited lab that performs extensive validation on each assay to meet federal CLIA requirements.

How are you able to offer the lowest cost per biomarker in the industry?

A. We bundle 17 biomarkers into a single sample collection, maximizing the data we collect from a single kit. Other companies like EverlyWell sell 2-4 markers per kit to maximize profits.

B. We sell the monthly Quantify subscription at cost. The reason we are doing this is to drive demand and leverage that to drive our costs down.

C. SiPhox, the company behind Quantify, develops blood testing hardware. We will be deploying our hardware in users' homes starting in 2023 to cut test costs further.

Note that we do not compromise on the quality or accuracy of our tests in any way.

Why should I use a wearable with Quantify?

Quantify is not just another blood testing service delivering raw data to users. We draw upon correlations between biomarkers and wearable data. This allows you to optimize your lifestyle to improve your biomarkers.
