The Total Testosterone Test is a blood test that measures the total concentration of testosterone circulating in the bloodstream, including testosterone bound to proteins and the free fraction.

Testosterone is an important androgen hormone produced mainly by the testes in males and in smaller amounts by the ovaries and adrenal glands in females.

It plays an essential role in reproductive function, sexual development, muscle growth, bone density, and overall hormonal health.

Why Is the Total Testosterone Test Recommended?

A healthcare professional may recommend this test to help evaluate:

• Low Testosterone: Investigation of possible testosterone deficiency.
• Male Reproductive Health: Assessment of hormonal factors associated with fertility and reproductive function.
• Sexual Health: Investigation of reduced libido or erectile difficulties.
• Muscle and Bone Health: Evaluation of hormonal factors affecting muscle mass and bone density.
• Female Hormonal Assessment: Investigation of suspected androgen excess, including symptoms such as excess facial hair or acne.
• Hormone Monitoring: Monitoring testosterone levels during prescribed hormonal treatment.

Sample Requirements

• Sample type: Blood, typically serum.
• Fasting: Follow laboratory instructions; fasting may be requested depending on the clinical assessment and laboratory protocol.
• Collection timing: Morning collection is generally preferred, particularly when evaluating low testosterone in men.
• Preparation: Inform your healthcare professional about medications, supplements, and hormone treatments.

Understanding Your Results

• Low Testosterone: May be associated with hypogonadism, certain testicular or pituitary conditions, or other medical factors.
• High Testosterone: May occur with testosterone supplementation, certain hormonal disorders, or other medical conditions.
• Normal Testosterone: Suggests levels are within the laboratory’s reference interval, but interpretation depends on symptoms and clinical history.

Testosterone levels vary with age, sex, time of collection, and health status. Abnormal results may require repeat morning testing and additional hormonal investigations.
