PrescribedRX uses a lab-based eligibility model for Testosterone Replacement Therapy. Qualification is determined by combining your total testosterone level (measured by a blood draw) with a standardized symptom assessment.
Common Symptoms of Low Testosterone #
- Low sex drive and decreased libido
- Fatigue, low energy, and lack of vitality
- Loss of lean muscle mass and strength
- Depressive mood, irritability, or mood swings
- Poor sleep and increased need for rest
- Reduced erectile function
- Decreased beard growth and body hair
Lab-Based Eligibility Thresholds #
| Total Testosterone Level | Eligibility |
|---|---|
| Under 250 ng/dL | Eligible for treatment |
| 250–350 ng/dL | Eligible with AMS score ≥ 27 |
| 350–450 ng/dL | Eligible with AMS score ≥ 37 (off-label) |
| 450–900 ng/dL | Normal physiological range — not eligible |
📌 Important: Your testosterone blood draw must be completed between 7:00 AM and 10:00 AM for accurate results. Testosterone levels naturally peak in the morning and can be misleadingly lower if drawn later in the day.
Required Labs for TRT Evaluation #
- Total Testosterone (morning draw, 7–10 AM)
- Hemoglobin / Hematocrit
- PSA (Prostate-Specific Antigen)
- LH (Luteinizing Hormone)
A total testosterone below 300 ng/dL, combined with at least 3 recognized symptoms, is generally considered diagnostic for Low T.
