What is a Testosterone (Total) Test?
The Testosterone (Total) test measures the entire amount of testosterone circulating in your bloodstream — including testosterone bound to proteins like albumin and SHBG, as well as free testosterone. As the primary male sex hormone, testosterone plays a vital role in physical development, reproductive health and emotional well-being. This test is a key diagnostic tool for identifying hormonal imbalances that affect energy levels, muscle mass, fertility, bone density and mood.
⚠ Important: For the most accurate results, blood should be drawn between 7:00 AM and 10:00 AM as testosterone levels naturally peak in the early morning and decline throughout the day. While fasting is not strictly required, avoid a heavy meal immediately before the test.
The Role of Testosterone in the Body
While often associated with men, testosterone is essential for both genders:
- Male Vitality — Regulates sex drive (libido), muscle mass, strength, bone density, red blood cell production and sperm production
- Female Hormonal Balance — In women, supports bone health, ovarian function and libido. Elevated levels are often a marker for PCOS
- Puberty Monitoring — Investigates early or delayed puberty in children and teenagers
- Pituitary & Hypothalamus Assessment — Helps identify issues with the glands that regulate hormone production
Normal Testosterone Range
| Category | Normal Total Testosterone Range |
|---|---|
| Adult Men (20–49 years) | 300 – 1,000 ng/dL |
| Adult Men (50+ years) | 200 – 800 ng/dL |
| Adult Women | 15 – 70 ng/dL |
| Prepubertal Boys | Below 20 ng/dL |
| Prepubertal Girls | Below 10 ng/dL |
Testosterone levels decline naturally with age in men — typically by about 1% per year after age 30. Your doctor will interpret results alongside symptoms and other hormone tests.
Total Testosterone vs Free Testosterone — What is the Difference?
Understanding the two forms of testosterone:
- Total Testosterone — measures all testosterone in the blood including both bound and free fractions. This is the standard first-line test.
- Free Testosterone — measures only the unbound fraction (about 2–3% of total) that is biologically active and available to tissues. Free testosterone is more clinically relevant when Total Testosterone is borderline normal but symptoms persist.
- SHBG (Sex Hormone Binding Globulin) — the protein that binds testosterone. High SHBG reduces free testosterone even when Total Testosterone is normal. SHBG is often ordered alongside testosterone in obesity and thyroid disorders.
When is a Testosterone Test Recommended?
Your doctor may recommend a Testosterone test if you experience:
- In Men: Low sex drive, erectile dysfunction, infertility, decreased muscle mass, fatigue, depression, gynecomastia (breast tissue enlargement), or bone loss
- In Women: Irregular or absent periods, excess facial or body hair (hirsutism), acne, hair thinning, infertility or suspected PCOS
- In Children: Early or delayed puberty, premature development of secondary sexual characteristics
- General: Monitoring testosterone replacement therapy, assessing pituitary or adrenal gland disorders
What Conditions Does Testosterone Test Help Diagnose?
- Hypogonadism (low testosterone in men)
- Polycystic Ovary Syndrome (PCOS) in women
- Infertility in men and women
- Delayed or precocious puberty
- Adrenal gland tumors or disorders
- Testicular tumors
- Klinefelter syndrome
- Monitoring testosterone replacement therapy
- Pituitary gland disorders

Tests Commonly Ordered Alongside Testosterone
- Free Testosterone — measures the biologically active fraction when Total Testosterone is borderline
- LH (Luteinizing Hormone) — distinguishes between primary (testicular) and secondary (pituitary) hypogonadism
- FSH (Follicle-Stimulating Hormone) — assesses sperm production and fertility alongside testosterone
- SHBG (Sex Hormone Binding Globulin) — helps calculate free testosterone when SHBG may be abnormal
- Prolactin — elevated prolactin suppresses testosterone and is ruled out in low-T evaluation
- Thyroid Profile (TSH) — thyroid disorders can affect testosterone levels
- DHT (Dihydrotestosterone) — in cases of hair loss or prostate issues

Frequently Asked Questions
Q1. What is the Testosterone test used for?
The Testosterone (Total) test measures testosterone levels in the blood. It is used to diagnose low testosterone (hypogonadism) in men, investigate PCOS and hirsutism in women, assess infertility, evaluate delayed or early puberty in children and monitor testosterone replacement therapy.
Q2. What is the normal Testosterone level for men?
Normal Total Testosterone for adult men aged 20–49 is 300–1,000 ng/dL. For men over 50 the range is typically 200–800 ng/dL. Levels below 300 ng/dL in adult men with symptoms are generally considered low and warrant further investigation. Values vary slightly by laboratory.
Q3. What is the normal Testosterone level for women?
Normal Total Testosterone for adult women is 15–70 ng/dL. Levels above 70 ng/dL in women may indicate PCOS, adrenal disorders or an androgen-secreting tumor. Low testosterone in women can contribute to low libido, fatigue and bone loss.
Q4. What is the Testosterone test price at Apollo Diagnostics Kolkata?
The Testosterone (Total) test price at Apollo Diagnostics is ₹850. We use CLIA technology for accurate hormonal measurement. Home collection is available free on orders above ₹2,000.
Q5. Why should the Testosterone test be done in the morning?
Testosterone levels follow a circadian rhythm — they are highest between 7–10 AM and gradually decline throughout the day. A blood draw in this window gives the most accurate and clinically meaningful result. An afternoon draw may show levels 20–30% lower than the true morning peak, which can lead to misdiagnosis of low testosterone.
Q6. What are the symptoms of low Testosterone in men?
Common symptoms of low testosterone (hypogonadism) in men include reduced sex drive, erectile dysfunction, decreased muscle mass and strength, increased body fat, fatigue, depression, difficulty concentrating, reduced bone density, infertility and decreased body or facial hair. These symptoms should be evaluated alongside a blood test for accurate diagnosis.
Q7. Can high Testosterone in women indicate PCOS?
Yes. Elevated testosterone is one of the hallmark features of Polycystic Ovary Syndrome (PCOS). High testosterone in women can cause irregular periods, excess facial and body hair (hirsutism), acne, scalp hair thinning and difficulty conceiving. A testosterone test is usually ordered alongside LH, FSH and AMH when PCOS is suspected.
