How It Works
Enter your lab values for each marker. The tool will indicate whether each value is below range, in range, optimal, or above range, with an explanation of what each marker means for men on TRT.
TRT Lab Reference
Enter your lab values and see where you fall relative to reference ranges and optimal ranges for men on TRT.
Enter your lab values to see where you fall relative to reference and optimal ranges.
(ng/dL)
Reference: 264–916 ng/dL | Optimal: 500–900 ng/dL
Primary male sex hormone. Optimal range for symptom resolution is typically 500-900 ng/dL.
(pg/mL)
Reference: 5–21 pg/mL | Optimal: 15–25 pg/mL
Bioavailable testosterone not bound to SHBG. Many practitioners target the upper range.
(pg/mL)
Reference: 10–40 pg/mL | Optimal: 20–35 pg/mL
Estrogen level. Both too high and too low cause symptoms. Manage with AI if needed.
(nmol/L)
Reference: 10–57 nmol/L | Optimal: 20–40 nmol/L
Sex hormone-binding globulin. High SHBG reduces free testosterone availability.
(mIU/mL)
Reference: 1.7–8.6 mIU/mL | Optimal: 3–7 mIU/mL
Luteinizing hormone. Suppressed on TRT; used to assess HPTA function off-cycle.
(mIU/mL)
Reference: 1.5–12.4 mIU/mL | Optimal: 2–8 mIU/mL
Follicle-stimulating hormone. Important for fertility assessment.
(%)
Reference: 38–50 % | Optimal: 40–48 %
Red blood cell percentage. TRT can elevate hematocrit; monitor regularly.
(ng/mL)
Reference: 0–4 ng/mL | Optimal: 0–2.5 ng/mL
Prostate-specific antigen. Monitor on TRT for prostate health.
