Lab Tests for Low Testosterone
Low testosterone (hypogonadism) affects an estimated 4-5 million men in the United States and can cause fatigue, reduced libido, muscle loss, mood changes, and difficulty concentrating. Lab testing is the only definitive way to diagnose low testosterone and determine whether the cause is primary (testicular) or secondary (pituitary). A comprehensive testosterone workup includes total and free testosterone along with supporting markers. JustLabs lets you order these tests online at transparent prices, no doctor visit required.

Understanding Your Results
| Test | Normal Range | Low Means | High Means |
|---|---|---|---|
| Total Testosterone | Male: 264–916 ng/dL | Low testosterone confirmed | Normal or elevated — less likely cause of symptoms |
| Free Testosterone | Male: 5–21 ng/dL | Bioavailable testosterone insufficient | Adequate free hormone despite low total |
| SHBG | Male: 10–57 nmol/L | More free testosterone available | Binding excess testosterone — can cause low free T |
| LH | Male: 1.7–8.6 mIU/mL | Pituitary not signaling testes (secondary) | Testes not responding to signals (primary) |
