Testosterone Test Comprehensive

Why take this test?

Deeper hormone insight, performance, energy and libido

Testosterone is not just about how much you have — it’s about how much your body can actually use.

It’s common to have testosterone levels within range, yet still experience low energy, reduced libido, poor recovery, or a drop in performance. This is often due to testosterone being bound and unavailable, rather than a simple deficiency.

This advanced test goes further than a basic check, providing a more complete assessment of your hormone profile and how effectively your testosterone is functioning.

Measures both total and biologically active testosterone

Identifies the impact of binding proteins such as SHBG

Helps explain symptoms that standard testing may miss

Professional blood draw included.
Samples analysed in accredited UK laboratories for accurate and reliable results.

Testosterone Advanced Test

What does it test?

Total & free testosterone

SHBG, FAI

Albumin

Low Energy, Reduced Libido, or Muscle Loss? Discover Your Testosterone Levels

Feeling constantly tired, lacking motivation, or noticing changes in your strength, mood, or sex drive? These could be signs of a testosterone imbalance.

Testosterone is a vital hormone for both men and women. It supports energy levels, muscle mass, libido, fertility, and overall wellbeing. When levels are too low—or in some cases too high—it can lead to symptoms that are often dismissed as stress, ageing, or lifestyle-related.

Common signs of testosterone imbalance include:

  • Low sex drive or erectile dysfunction
  • Fatigue and low energy
  • Mood changes, irritability, or brain fog
  • Loss of muscle mass and strength
  • Weight gain, especially around the abdomen
  • Irregular periods, excess hair, or acne in women

Why Testosterone Imbalance Is Often Overlooked

Testosterone levels don’t tell the full story on their own. Much of your testosterone is bound to proteins in the blood, meaning only a small portion is “free” and active. This is the form your body can actually use—and low active levels can still cause symptoms even when total levels appear normal.

Imbalances can be caused by factors such as age, stress, obesity, chronic illness, hormonal conditions like PCOS, or certain medications. Left unaddressed, they can impact fertility, bone health, physical performance, and confidence.

Who Should Consider a Testosterone Blood Test?

Testing may be helpful if you:

  • Experience ongoing fatigue, low mood, or poor concentration
  • Notice reduced libido or sexual performance issues
  • Are struggling with muscle loss or weight gain
  • Have symptoms of hormonal imbalance or PCOS
  • Are concerned about fertility or hormone health

  • No self Testing

Comprehensive Testosterone Blood Test

Total+ free testosterone, ratio, albumin, SHBG, FAI. Deeper for “usable” hormone – spots why total seems OK but symptoms persist (e.g., high SHBG trapping it). (Biomarkers: Total + 5 more.)

  • Best For: Complex cases like ED, muscle loss, PCOS, TRT tracking, or obesity where binding affects availability.
Comprehensive Biomarkers:
  • Total Testosterone: Overall production (bound + free); assesses drive, muscle, fertility baselines.
  • Free Testosterone: Unbound/active form (1-2%); key for real effects on energy/libido.
  • Free/Total Ratio: Proportion available; low ratio hints binding problems.
  • Albumin: Loosely binds testosterone; helps calculate bioavailable amount.
  • SHBG (Sex Hormone Binding Globulin): Tight binder; high levels “trap” testosterone, causing symptoms despite normal total.
  • Free Androgen Index (FAI): Ratio of total to SHBG; estimates usable androgen for PCOS/ED diagnosis.

Collection method: Venous blood
Results available: 1-2 days after the sample has reached the laboratory.

Total Testosterone

This measures the overall amount of testosterone in your blood, including both active (free) and inactive (bound) forms.

Free Testosterone

This is the unbound form that’s biologically active and available for your body to use. It’s often a better indicator of how your body is really functioning hormonally.

 Free/Total Testosterone ratio

The Free/Total Testosterone Ratio is a biomarker that helps determine how much of your total testosterone is actually available for your body to use.

Albumin

Some testosterone in your blood is loosely bound to albumin, and this portion is considered bioavailable — meaning it can still be used by your body.

SHBG (Sex Hormone Binding Globulin)

While not testosterone itself, SHBG affects how much testosterone is available. High SHBG can reduce free testosterone levels.

Free Androgen Index (FAI)

A calculated ratio of total testosterone to SHBG. It helps estimate how much usable testosterone is circulating.
