TRT and Blood Work: Complete Guide
Testosterone Replacement Therapy (TRT) requires careful monitoring through regular blood work. This guide helps you understand your hormone panel.
Essential Tests for TRT Monitoring
Primary Hormones - Total Testosterone: Overall testosterone levels - Free Testosterone: Bioavailable testosterone - Estradiol (E2): Estrogen levels (can rise on TRT) - SHBG: Sex Hormone Binding Globulin
Safety Markers - Hematocrit/Hemoglobin: Red blood cell levels (can increase on TRT) - PSA: Prostate health marker - Lipid Panel: Cardiovascular health - Liver Enzymes: Liver function
Optimal Ranges for TRT Patients
| Marker | Optimal Range | Notes |
|---|---|---|
| Total T | 600-900 ng/dL | Peak levels (trough may be lower) |
| Free T | 15-25 pg/mL | More important than total |
| E2 | 20-35 pg/mL | Monitor for symptoms |
| Hematocrit | <52% | Higher risk above 54% |
Testing Timing
- Injections: Test at trough (before next injection)
- Gels/Creams: 2-4 hours after application
- Pellets: 4-6 weeks after insertion
Common Issues & Solutions
High Estradiol - Symptoms: Water retention, mood issues, gynecomastia - Solutions: AI adjustment, injection frequency change
Elevated Hematocrit - Risk: Blood clots, stroke - Solutions: Blood donation, hydration, dose adjustment
Low Free T Despite Good Total T - Cause: High SHBG binding testosterone - Solutions: More frequent injections, SHBG reduction strategies
Red Flags to Watch
- Hematocrit >54%
- PSA rapid increase
- Liver enzyme elevation
- Significant lipid changes

Reading is useful. Bringing a clearer story is better. E-Labus helps patients organize the actual report, understand what changed, and walk in with sharper questions than generic AI summaries can give.
