How to Test for Testosterone Level?
Share
Testosterone level testing is one of the most frequently requested hormone investigations at healthcare nt sickcare across Pune and Pimpri-Chinchwad — and for good reason. Men in their 30s and 40s presenting with unexplained fatigue, reduced libido, poor muscle recovery, or mood changes are increasingly asking whether declining testosterone could be the underlying cause. The answer, in many cases, is yes. At healthcare nt sickcare, a transparent-pricing diagnostic service operating in Aundh, Pune since 2007, testosterone tests are available with early-morning home sample collection — the critical timing requirement for an accurate baseline result. This article explains what a testosterone test measures, what normal ranges look like in men and women, when to test, and what the results mean for your health.
Testosterone deficiency in men — clinically termed hypogonadism — is more prevalent in India than commonly recognised. A study published in the Indian Journal of Endocrinology and Metabolism found that late-onset hypogonadism affects approximately 20–30% of men over the age of 40 in urban Indian populations, with rates rising significantly with comorbidities such as Type 2 diabetes, obesity, and metabolic syndrome.
What Is a Testosterone Test and What Does It Measure?
A testosterone blood test measures the concentration of testosterone hormone circulating in the bloodstream, typically reported as total testosterone in nanograms per decilitre (ng/dL) or nanomoles per litre (nmol/L). Testosterone belongs to the androgen class of steroid hormones and is produced primarily in the Leydig cells of the testes in men, and in smaller amounts by the ovaries and adrenal cortex in women.
In clinical practice, laboratories report total testosterone — which includes both the fraction bound to proteins (sex hormone-binding globulin and albumin) and the small free fraction. For a more complete picture, particularly when total testosterone is borderline, physicians may additionally order free testosterone and SHBG (Sex Hormone-Binding Globulin), which together allow calculation of the bioavailable testosterone actually available to tissues. Our total testosterone test and free testosterone test are both available with home collection across Pune.
Testosterone Normal Range — Men and Women
Testosterone normal ranges differ significantly between men and women, and also vary with age. The following reference values are used by NABL-accredited laboratories in India:
| Group | Total Testosterone (ng/dL) | Clinical Interpretation |
|---|---|---|
| Adult men (20–50 yrs) | 300 – 1,000 ng/dL | Normal range |
| Men below 300 ng/dL | < 300 ng/dL | Low — evaluate for hypogonadism |
| Men over 50 yrs | 200 – 800 ng/dL | Age-adjusted range |
| Adult women (pre-menopausal) | 15 – 70 ng/dL | Normal range |
| Women (post-menopausal) | 7 – 40 ng/dL | Lower due to reduced ovarian production |
Testosterone levels follow a diurnal rhythm — they are highest between 7 and 10 AM and decline through the day by 30–40%. This is why all testosterone tests should be collected as an early-morning fasting sample. Results drawn in the afternoon are frequently falsely low and clinically unreliable.
Testosterone in Men — Functions and Symptoms of Deficiency
In men, testosterone is the primary anabolic and androgenic hormone, governing a wide range of physiological functions beyond sexual health. It regulates sperm production, maintains muscle mass and bone density, controls fat distribution, supports red blood cell production, and modulates mood, cognition, and energy. Testosterone also influences cardiovascular health — low levels are associated with insulin resistance, dyslipidaemia, and increased cardiovascular event risk, as reviewed in our related article on what happens during a heart attack.
Signs and symptoms of low testosterone in men that warrant a blood test include: persistent fatigue unrelated to sleep quality; reduced sexual desire and fewer spontaneous erections; difficulty maintaining muscle mass despite regular exercise; increased body fat, particularly centrally; depressed mood, irritability, or poor concentration; reduced body and facial hair; gynaecomastia (breast tissue enlargement); and infertility or reduced sperm parameters. These symptoms typically develop gradually over months to years as testosterone declines.
Testosterone for Women — Why It Matters Too?
Testosterone is not exclusively a male hormone — women produce and require testosterone for libido, bone density, muscle maintenance, mood regulation, and cognitive function. In women, it is produced by the ovaries and adrenal glands. Abnormal testosterone levels in women can signal either deficiency or excess, with distinct clinical consequences.
Low testosterone in women presents as reduced libido, persistent fatigue, mood changes, and reduced bone density — symptoms that often overlap with oestrogen deficiency during perimenopause. Elevated testosterone in women — caused by polycystic ovarian syndrome (PCOS), congenital adrenal hyperplasia, or androgen-secreting tumours — presents as hirsutism (excess facial and body hair), acne, irregular menstrual cycles, and fertility difficulties. A PCOS test profile that includes testosterone alongside LH, FSH, and DHEA-S is typically ordered when excess androgen is suspected in women in Pune.

What Causes Low Testosterone? Common Triggers
Testosterone deficiency has both primary causes (originating in the testes or ovaries) and secondary causes (originating in the pituitary or hypothalamus). The most clinically common causes include age-related decline — testosterone decreases by approximately 1–2% per year after the age of 30; obesity and metabolic syndrome — adipose tissue converts testosterone to oestradiol via aromatisation; Type 2 diabetes; chronic stress with elevated cortisol; sleep deprivation; opioid analgesic use; anabolic steroid abuse — which suppresses the hypothalamic-pituitary-testicular axis; and specific conditions including Klinefelter syndrome, pituitary adenoma, and haemochromatosis.
Identifying the underlying cause determines whether treatment should target the testes directly (primary hypogonadism) or the signalling pathway (secondary hypogonadism). This is why testosterone testing is almost always accompanied by LH (luteinising hormone) and FSH tests — the pituitary hormones that stimulate testicular testosterone production. Elevated LH with low testosterone indicates primary testicular failure; low LH with low testosterone points to a pituitary or hypothalamic problem. The DHEA-S test is additionally useful when adrenal androgen contribution needs to be assessed.

A testosterone test is recommended for men experiencing persistent fatigue, reduced libido, difficulty maintaining muscle mass, mood changes, reduced facial or body hair, or suspected infertility. Men over 40 should consider a baseline testosterone test even without symptoms, as age-related decline is gradual and often not recognised until significant deficiency has occurred. Women with irregular periods, excess facial hair, acne, or suspected PCOS should also have testosterone tested as part of a hormonal panel. First baseline testing is typically advised around age 30 for men with risk factors, and annually after age 40. For those already on testosterone replacement therapy, monitoring every 3 months — alongside PSA (Prostate Specific Antigen) — is the standard clinical protocol.
Yes — testosterone follows a clear diurnal pattern, with levels peaking between 7 and 10 AM and declining by 30–40% through the afternoon and evening. This diurnal variation is most pronounced in younger men and less marked in men over 60. Because of this fluctuation, all testosterone blood tests must be collected as early-morning samples — ideally before 10 AM and in a fasting state — to ensure the result reflects the true baseline peak concentration. Testosterone results drawn in the afternoon are frequently falsely low and are not considered clinically reliable for diagnostic purposes. At healthcare nt sickcare, home collection appointments for testosterone are preferentially scheduled between 7 and 9 AM across Pune and Pimpri-Chinchwad for this reason.
A full hormonal evaluation for suspected testosterone deficiency includes: total testosterone (the primary test); free testosterone — the bioavailable fraction, particularly useful when total is borderline; SHBG (Sex Hormone-Binding Globulin) — helps calculate free testosterone and explains discordant symptoms; LH and FSH — pituitary hormones that determine whether the problem is primary (testicular) or secondary (pituitary/hypothalamic); prolactin — elevated prolactin suppresses testosterone production and can indicate a pituitary adenoma; DHEA-S — reflects adrenal androgen contribution; and thyroid function tests, since hypothyroidism raises SHBG and reduces free testosterone. In women, the panel also includes estradiol and progesterone. A fasting lipid profile and HbA1c are commonly added given the strong association between metabolic syndrome and low testosterone.
Taking testosterone supplements or testosterone boosters without first testing your actual blood testosterone level is clinically inadvisable and potentially harmful. Over-the-counter "testosterone boosters" — typically containing zinc, ashwagandha, fenugreek, or D-aspartic acid — have limited evidence for efficacy, but more importantly, starting any testosterone-modifying regimen without a baseline blood test means there is no objective measure to confirm deficiency or to track response. Prescription testosterone replacement therapy (TRT) — including injections, gels, and patches — is only appropriate when blood testosterone is confirmed low on at least two morning samples. Exogenous testosterone without monitoring can suppress the hypothalamic-pituitary axis, reduce sperm production, elevate haematocrit (increasing clotting risk), and affect prostate health. Always test first, then treat under medical supervision.
Yes — several evidence-based lifestyle interventions can support healthy testosterone production and slow age-related decline. Resistance training (weight lifting) consistently shows a testosterone-boosting effect in both younger and older men. Adequate sleep — 7 to 9 hours per night — is critical, as the majority of daily testosterone production occurs during deep sleep stages. Reducing body fat, particularly central adiposity, decreases aromatase enzyme activity that converts testosterone to oestrogen. A diet adequate in zinc (found in pumpkin seeds, legumes, meat), magnesium, and healthy fats (olive oil, nuts, avocados) supports steroidogenesis. Reducing alcohol intake — heavy use suppresses Leydig cell testosterone production — and stopping smoking also have measurable positive effects. These lifestyle measures are effective as primary interventions for borderline deficiency and as adjuncts to TRT in confirmed hypogonadism.
