A Testosterone Replacement Therapy (TRT) Blood Test is a comprehensive health assessment used to measure testosterone levels and monitor the body’s response to testosterone replacement therapy. It also evaluates blood health, cholesterol, liver and kidney function, thyroid health, prostate health, and metabolic markers to help ensure treatment remains both safe and effective.

This test is suitable for adult men who are considering testosterone replacement therapy, are currently receiving TRT, or require regular monitoring of hormone levels and general health. It may also be recommended for individuals experiencing symptoms associated with low testosterone, such as fatigue, reduced libido, or decreased muscle strength.

The frequency of testing depends on your individual treatment plan and your healthcare professional’s recommendations. Blood tests are commonly performed before starting TRT, several weeks after treatment begins, and then at regular intervals to monitor hormone levels and overall health.

Fasting is not usually required for this blood test. However, if your healthcare professional recommends fasting because additional tests are being performed at the same time, you should follow those instructions. Staying well hydrated before your appointment is also recommended.

Testosterone replacement therapy can influence multiple systems within the body, not just hormone levels. This comprehensive 60 biomarker profile helps assess blood cell production, cholesterol, liver and kidney function, blood sugar control, thyroid function, prostate health, and other important health markers to provide a complete picture of your overall wellbeing.

Yes. Testosterone therapy may stimulate the production of red blood cells, which can increase haemoglobin and haematocrit levels. Regular monitoring is important because significantly elevated levels may require further clinical assessment or adjustments to treatment.

Prostate Specific Antigen (PSA) is commonly monitored in men receiving testosterone replacement therapy as part of routine prostate health assessment. PSA levels can be influenced by several non-cancerous conditions, so results should always be interpreted alongside your medical history and clinical assessment.

This blood test measures testosterone levels accurately but does not diagnose low testosterone on its own. A diagnosis should always be made by a qualified healthcare professional, taking into account your symptoms, medical history, physical examination, and blood test results.

Yes. Testosterone therapy, anabolic steroids, certain hormone treatments, corticosteroids, and some other medications may influence hormone levels or other biomarkers included in this profile. Always inform your healthcare professional about any prescription medicines, supplements, or over-the-counter products you are taking before testing.

Results are typically available within 3 working days after your blood sample has been analysed. Once available, they should be reviewed with a qualified healthcare professional who can explain your results and discuss whether any further investigation or treatment adjustments are required.

Yes. This profile has been designed specifically to support ongoing monitoring of testosterone replacement therapy. Regular testing helps assess treatment effectiveness, monitor hormone levels, and identify potential side effects affecting blood health, cholesterol, liver function, kidney function, or prostate health.

Yes. Factors such as sleep quality, body weight, exercise, alcohol intake, smoking, stress, and certain medical conditions can all influence testosterone levels. Lifestyle changes may also affect several other biomarkers included within this comprehensive health profile.
