Good to know.

  • Hormone tests are usually drawn early

    Testosterone runs highest in the morning, so guidelines ask for a sample before 10 a.m. A later draw can read lower.

  • Some tests need fasting

    Glucose, insulin and some lipid tests ask for 8 to 12 hours without food. Water is fine. Each test’s page says whether it needs it.

  • One result is one moment

    Many markers move from day to day. Guidelines often ask for a second draw before reading much into a single number.

Questions.

Can I order a test today?

Not yet. Orders open once the lab partnership and our terms are final. Join the waitlist and we’ll email you the day they open.

Where is my blood drawn?

At a certified lab location. Our lab partner’s network has more than 4,500 across the US. Each test page says whether you need to fast first.

Do these tests diagnose anything?

No. A lab test measures markers in your blood. What a result means for you is a question for a licensed clinician.

Why do hormone tests ask for a morning draw?

Testosterone and cortisol follow a daily rhythm and run highest in the morning, so an early draw makes results comparable from one test to the next.

What does fasting mean for a blood test?

Nothing to eat or drink except water for the hours the test asks, usually 8 to 12. If you take medicines, ask your clinician whether to take them before the draw.

The waitlist makes no eligibility, diagnosis, treatment, prescribing, or medication access decisions.

Clinical questions, eligibility, and care decisions happen later with a licensed provider, outside this form and only where legally available.
