Do I Need TRT? Low-Testosterone Symptoms & Diagnosis
How low testosterone is actually diagnosed — symptoms plus repeat morning blood tests below the reference range — and who genuinely qualifies for treatment.
How do I know if I actually have low testosterone and need TRT?
- •Diagnosis requires BOTH symptoms and biochemically low testosterone — not symptoms alone.
- •Guidelines call for two separate early-morning (≈7-10am) total-testosterone draws, when levels peak.
- •A commonly cited threshold is total testosterone repeatedly below ~300 ng/dL, though labs vary.
- •Free testosterone and SHBG matter when total T is borderline — high SHBG can mask a low free fraction.
- •Reversible causes (poor sleep, obesity, alcohol, opioids, acute illness) should be excluded first.
