Follow-up labs and monitoring
Follow-up labs show how treatment is working and help your provider spot problems. On testosterone therapy they track your testosterone level, red blood cell count and prostate (PSA), alongside blood pressure readings and how you feel. Your coordinator books them at a lab near you, and your provider reviews each result with you and can change or stop the plan.
Why monitoring is part of TRT
Some of testosterone's risks, such as a high red blood cell count, are found with blood tests, so monitoring is part of the plan from the first visit.2
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
The Endocrine Society says screening and monitoring are needed once testosterone therapy starts, because long-term safety, including for prostate cancer, is not established.3
What is checked
Guidelines call for a standard monitoring plan that covers symptoms and side effects, testosterone and hematocrit levels, and prostate cancer risk in the first year.1 The label adds blood pressure and blood counts.2,4
| Check | Why | Source |
|---|---|---|
| Testosterone level | To keep it in the mid-normal range guidelines aim for | 1 |
| Red blood cell count (hemoglobin, hematocrit) | Testosterone can raise it; the label calls for periodic checks on long-term treatment | 1,2 |
| PSA and prostate risk | Prostate risk is evaluated during the first year | 1 |
| Blood pressure | Testosterone can raise it; checked periodically, especially with high blood pressure | 2,4 |
| Symptoms and side effects | To judge whether treatment is helping and whether to adjust it | 1 |
Your provider may add other tests, such as cholesterol, which the label says can rise on testosterone.2
The schedule
Your provider sets your follow-up schedule from your medication, your results and your health, and your coordinator books each draw.
Follow-up labs are drawn at a lab near you, and in most cases you can walk in. Some offices can also draw your blood.
What happens with the results
Your provider reviews each set of results with you and decides whether to continue, adjust the dose, pause or stop. Each new supply needs your provider's prescription and your OK, so the results feed directly into whether the next supply is appropriate.
Between draws, tell your provider about leg pain or swelling, sudden shortness of breath, or an erection that won't go away, and call 911 in an emergency.2 More on the risks: TRT safety and monitoring
Other treatments
Follow-up for other treatments is set by your provider.
- Women's hormone therapy: follow-up visits review symptoms, side effects and whether to continue. Important Safety Information for hormone therapy
- Medical weight loss: follow-up visits review progress, side effects and your other medicines.
Labs for these are ordered when your provider needs them.
Cost
Your coordinator explains which labs and visits each step covers, and what they cost, before you pay. You get a receipt by email. No membership and no automatic billing. How pricing works
Where to start
If you're new, start with the testosterone panel. If you're already a patient, your coordinator books your next draw.
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.
Questions
How often will I need blood work on TRT?
What happens if a result is out of range?
Your provider reviews it with you and can change the dose, pause or stop treatment, or order more tests. Your coordinator books anything that follows.
Do I need to keep sending blood pressure readings?
Yes. Testosterone can raise blood pressure, and the label calls for checking it periodically, especially if you have high blood pressure. Your provider tells you how often to share readings.2
Can I skip a follow-up lab?
Talk to your coordinator first. Your provider uses these results to decide whether the next supply is appropriate, and each new supply needs your provider's prescription and your OK.
Are follow-up labs part of the cost?
Your coordinator explains which labs and visits each step covers, and what they cost, before you pay. You get a receipt by email.
Do other treatments need follow-up labs?
Your provider decides. For hormone therapy and weight care, follow-up visits review symptoms, side effects and whether to continue, and labs are ordered when your provider needs them.
