Compare Lab Test PricesThe blood test that measures testosterone is called a serum testosterone test, often divided into total testosterone and free testosterone. This simple blood draw is the gold standard for assessing male and female hormone health Today, helping diagnose low testosterone (hypogonadism), erectile dysfunction, infertility, or hormonal imbalances related to aging, obesity, or pituitary disorders. At Any Lab Test Now, we offer direct access to this test without a doctor's visit.
Understanding Testosterone Blood Tests
Total Testosterone vs. Free Testosterone
Total testosterone measures both bound and unbound testosterone in your blood. Most testosterone is bound to proteins like sex hormone-binding globulin (SHBG) and albumin. Free testosterone is the unbound, bioavailable fraction that your body can use. For a complete picture, many providers order both tests together, especially if symptoms suggest low testosterone but total levels appear normal.
When to Get Tested
Common reasons to test testosterone include:
- Low libido or erectile dysfunction
- Fatigue, depression, or reduced muscle mass
- Infertility or irregular menstrual cycles in women
- Monitoring testosterone replacement therapy (TRT)
- Suspected pituitary or adrenal disorders
How the Test Works
Testosterone levels fluctuate throughout the day, peaking in the morning. For accurate results, blood is typically drawn between 7 a.m. and 10 a.m. Fasting is not required, but your doctor may recommend it if other hormones are checked simultaneously. Results usually return within 1–3 business days.
Normal Testosterone Ranges (Standards)
| Population | Total Testosterone (ng/dL) | Free Testosterone (pg/mL) |
|---|---|---|
| Adult men (19–39 years) | 264–916 | 8.7–25.1 |
| Adult men (40+ years) | 200–890 | 6.8–21.5 |
| Adult women (19–49 years) | 8–60 | 0.3–2.5 |
| Postmenopausal women | 5–40 | 0.1–1.8 |
Note: Ranges vary by lab. Always consult your results with a healthcare professional.
Why Testosterone Testing Matters today
With rising awareness of male and female hormone health, testosterone testing has become a cornerstone of preventive care. Low testosterone affects an estimated 4–5 million men in the U.S., and many go undiagnosed. Testing can also reveal issues like polycystic ovary syndrome (PCOS) in women, adrenal tumors, or side effects from medications. Early detection allows for lifestyle changes, supplementation, or medical intervention.
