How Often Should Men on TRT Get Their Blood Drawn?

What You Need To Know | OptiVena Mobile Lab Service Phoenix, AZ

Why Does TRT Increase Red Blood Cells?

Testosterone stimulates your body to produce more red blood cells. While this is beneficial for oxygen transport and muscle function, excess red blood cells can cause your blood to become too thick—a condition known as polycythemia.

Symptoms of High Hemoglobin and Hematocrit Levels

✅ Fatigue or sluggishness
✅ Headaches or dizziness
✅ Flushed or reddened skin
✅ High blood pressure
✅ Shortness of breath
✅ Increased risk of clotting or stroke

Since polycythemia develops gradually, many men don’t realize they have it until they start experiencing symptoms—or worse, face a serious health complication. That’s why regular blood testing and proactive treatment are key.

How Often Should You Check Your Hemoglobin & Hematocrit Levels?

Doctors typically recommend checking your blood levels:

> Before starting TRT – Establish a baseline.

> 3-6 months after starting TRT – Identify any early changes.

> Annually or every 6 months after that – Monitor ongoing effects.

However, if you experience symptoms or have a history of elevated hematocrit, your doctor may recommend more frequent testing.

How Often Do You Need Therapeutic Phlebotomy?

If your hemoglobin and hematocrit levels are too high, your doctor may prescribe therapeutic phlebotomy—a medically necessary blood draw designed to thin your blood to safe levels.

The frequency of these blood draws varies based on individual factors, but common recommendations include:

🩸 Every 8-12 weeks – Standard for men with moderately elevated levels.
🩸 Every 4-6 weeks – For those with persistently high hematocrit.
🩸 As needed – Based on regular blood test results and symptoms.

Since TRT-related polycythemia is an ongoing issue, many men need routine therapeutic phlebotomy to maintain safe levels.

Why Blood Donation Centers May Turn You Away

Some men assume they can just donate blood instead of getting therapeutic phlebotomy. While this works for some, many blood donation centers have strict eligibility criteria and may turn you away if your hemoglobin or hematocrit levels are too high.



This is where therapeutic phlebotomy is different—it’s a doctor-prescribed treatment specifically tailored to your medical needs.
