Testosterone Test in Halol: When It Is Needed and How to Prepare

What testosterone does in the body

Testosterone is a hormone made mainly by the testes in men, and in much smaller amounts by the ovaries and adrenal glands in women. In men it supports muscle strength, bone density, red blood cell production, sex drive, sperm production and energy levels. In women, small amounts help with bone health, mood and libido.

Levels change with age, sleep, body weight, illness and some medicines, which is why a single number always needs to be read along with symptoms and a doctor's examination.

When doctors advise a testosterone test

• Men with low sex drive, erectile problems, low energy, reduced muscle mass or mood changes.
• As part of an infertility work-up, often along with a semen analysis.
• Delayed or early puberty in boys.
• Women with irregular periods, excess facial or body hair, acne or suspected PCOS.
• Monitoring people already on hormone treatment.

How to prepare for the sample

• Give the sample in the morning, ideally between 7 and 10 AM, when testosterone is naturally highest.
• Sleep normally the night before; heavy exercise just before the test is best avoided.
• Tell us about any medicines, steroids or supplements you take.
• Your doctor may ask for a repeat morning sample to confirm a low value.

Total and free testosterone

Most testosterone in blood is bound to proteins such as SHBG. Total testosterone measures all of it and is the usual first test. In some cases the doctor may also ask for free testosterone, SHBG, LH, FSH or prolactin to find the cause of an abnormal result.

Reference ranges differ by age, sex and testing method, so always compare your value with the range printed on your own report and discuss it with your doctor.
