What's included

A comprehensive assessment of hormone availability through four key clinical markers, analysed using high-precision laboratory equipment.

  • Total Testosterone: Measures the total amount of testosterone in the blood, including both bound and unbound hormone. This is the primary starting point for assessing your androgen status.
  • SHBG: Sex Hormone-Binding Globulin is a protein that binds testosterone. Variations in SHBG levels directly impact how much testosterone is actually available to your tissues.
  • Free Testosterone: The portion not tightly bound and readily available for biological activity. This is essential when symptoms persist despite a normal total testosterone result.
  • Albumin: A primary protein that binds hormones and helps with the clinical interpretation of hormone availability, providing a complete view of your status.
Suitable for People with low libido, fatigue, low mood, reduced muscle mass, or concerns about hormone balance.

What Is a Testosterone Blood Test?

This profile measures the level of testosterone in your bloodstream and assesses key binding proteins that determine how much hormone is biologically active and available to your body.

It is a vital marker for energy, bone strength, reproductive health, and overall hormonal balance for both men and women.

  • Vitality: Influences energy, mood, and daily motivation.
  • Body Composition: Key for muscle mass, recovery, and bone strength.
  • Wellness: Crucial for libido and reproductive function.

Who Should Consider This Test?

A Testosterone Profile is a key diagnostic tool if you are experiencing symptoms that suggest a potential hormone imbalance. Symptoms that may suggest low testosterone:

  • Low libido or sex drive
  • Erectile dysfunction
  • Persistent fatigue or reduced stamina
  • Low mood or poor motivation
  • Noticeable reduction in muscle mass
  • Unexplained increase in body fat
  • Difficulty recovering after exercise
  • General concerns about hormone balance
  • Fertility and reproductive health concerns

Early detection allows for professional clinical management and lifestyle optimization.

Why This Profile Matters

Why not just test testosterone alone? A single testosterone value does not always tell the full story. Some patients may have a total testosterone level that appears acceptable, but a high SHBG level may reduce the amount of usable testosterone available to the body. By looking at total testosterone together with free testosterone, SHBG, and albumin, this profile gives a more meaningful overview.

When should you test testosterone? For the most reliable assessment, testosterone testing is often best performed in the morning. Hormone levels can vary during the day, so consistent timing helps with interpretation.

What Can a Testosterone Profile Help Investigate?

  • Low testosterone symptoms
  • Male hormone imbalance
  • Erectile dysfunction
  • Reduced libido
  • Fertility concerns
  • Poor energy and recovery
  • Unexplained changes in body composition
  • Follow-up after previous abnormal hormone results
