SiPhox Home: The Future of At-Home Thyroid Testing

About SiPhox

We are a YC, Khosla Ventures, and Intel Capital-backed startup empowering everyday people to test their blood biomarkers painlessly at home and live healthier, longer.

SiPhox is the highest-rated self-testing company on the market. We have delivered 300k+ biomarker test results to date with our innovative mail-in tests via the SiPhox DTC wellness testing service and enterprise white-label platform.

What’s New

We're launching a waitlist for our comprehensive, clinical-grade at-home thyroid testing platform. For $79/month, users can test TSH, Free T4, Free T3, TPOAb, TGAb, and TG

No needles, no labs— just use our painless Easydraw arm collector patch, collect a small blood sample, and place it into the device.

Why It Matters

The numbers: ~20M Americans are living with hypothyroidism, and more with subclinical hypothyroidism. 1M+ have had their thyroid removed (~40-50k new thyroid cancer cases each year).

Completely at-home: no more travel, scheduling, or needle draws. Just a quick 5-10 minute sample collection vs. 2‑hour lab appointments.

Robust panel, affordable pricing: deeper insight at a lower cost relative to traditional labs (~$150/test).

Seamless doctor integration: sync results with your doctor easily, and manage across devices via our dashboard.

Telehealth support if you need it: work with a SiPhox-affiliated telehealth support team to optimize your thyroid health.

All-in-one health dashboard: track your results in a modern dashboard where you can connect your wearable devices, upload past test results from any lab, and chat with an in-context health coaching AI.

High accuracy, future-ready tech: SiPhox leverages silicon photonics, the tech that powers datacenter optical communication chips, to miniaturize a lab-grade blood testing instrument and cut the cost 300x without compromising on performance.

What’s Next

After we receive FDA clearance for thyroid testing, we’ll be focusing on launching sex hormone panels, an advanced cardiac and inflammation panel (ApoB, hsCRP, etc.), and more. These will all be compatible with the same device.

The SiPhox Home can measure up to 20 proteins and hormones in a single cartridge.
