Lab testing
Lab tests come first in every treatment and are repeated during treatment to check how it's going. Your coordinator arranges the panel your provider orders at a lab near you, usually as a walk-in, and a licensed provider reviews every result with you before anything is prescribed.
Prescription treatment requires an evaluation by a licensed healthcare provider, who decides whether treatment is appropriate for you. Not everyone qualifies. Completing an assessment, booking a visit, or paying a fee does not guarantee a prescription.
How lab testing works
Your coordinator arranges the panel your provider orders, you get your blood drawn at a lab patient service center near you, and your provider goes through the results with you at your visit.
- Ordering: your provider orders the panel, and your coordinator arranges it and tells you how to prepare.
- The draw: at a nearby lab patient service center, and in most cases you can walk in. Where available, a draw at one of our offices or a mobile visit may be offered.
- Results: a licensed provider reviews them with you, explains what they mean and decides with you whether treatment fits.
- During treatment: follow-up labs are scheduled periodically, and your coordinator books them.
Which labs, for which treatment
The panel depends on why you're being seen. Your provider decides what to order.
- The testosterone panel: morning testosterone tests, repeated to confirm, plus the checks guidelines call for before treatment.1
- Women's hormone therapy: labs that fit your symptoms and history. Important Safety Information for hormone therapy
- Medical weight loss: labs that fit your health history before medication is considered.
- Follow-up labs and monitoring: the checks repeated while you're on treatment.
Testosterone testing
Low testosterone is diagnosed from symptoms plus consistently low results on morning tests, so one result is never enough. Guidelines call for at least two early-morning, fasting tests, with a common clinical threshold near 300 ng/dL.2
The label for testosterone also asks that the diagnosis be confirmed with morning tests on at least two separate days before treatment.3 The Endocrine Society notes that assays differ between labs, so the same sample can read low at one lab and normal at another.2 What a morning testosterone blood test measures
Testosterone is FDA-approved for men with low testosterone caused by certain medical conditions. Its safety and effectiveness for low testosterone due to aging alone have not been established. Testosterone can raise blood pressure and red blood cell count, reduce sperm production and fertility, and requires monitoring of the prostate and blood levels. Your provider will review the benefits and risks and monitor you with regular labs. Important Safety Information for testosterone

Questions
Where do I get my blood drawn?
At a lab patient service center near you. Your coordinator arranges the panel your provider orders and points you to the location, and in most cases you can walk in. Where available, a draw at one of our offices or a mobile visit may be offered.
Do I need to fast?
For testosterone, guidelines call for early-morning, fasting tests. Your coordinator gives you the instructions for your specific panel when it's ordered.2
Who reviews my results?
A licensed provider goes through your results with you at your visit and explains what they mean for you. Treatment starts only after your lab results are in and a licensed provider has gone through them with you.
Can I use labs I had done somewhere else?
Share them with your coordinator. Your provider decides whether they meet the testing requirements, such as morning timing and repeat testing for testosterone, or whether new labs are needed.1
How often are labs repeated during treatment?
Your provider sets the schedule based on your treatment and results. For testosterone, guidelines call for checking testosterone, red blood cell count and prostate risk during the first year.1
