Testosterone Plus Profile

Want the Full Picture of Your Testosterone Health?

If you’re experiencing symptoms like low energy, mood changes, or reduced libido, a total testosterone test might not be enough. This Testosterone Plus Profile gives a more accurate picture of how much testosterone is actually available for your body to use.

What this test includes:

This profile measures:

• Total Testosterone – the total amount of testosterone circulating in your blood
• Sex Hormone Binding Globulin (SHBG) – a protein that binds to testosterone, affecting how much is usable
• Albumin – another protein that carries hormones through your bloodstream

From these values, your Free Androgen Index (FAI) can be calculated — giving insight into how much active (or “free”) testosterone your body can access.

Why get tested?

This test helps identify or monitor:

• Hypogonadism (low testosterone), linked to fatigue, low libido, infertility, and muscle loss
• Erectile dysfunction, to assess hormonal causes
• Male infertility, where testosterone imbalance may affect sperm production
• Puberty issues in adolescents, such as delayed or early development
• PCOS in women, which may present with elevated testosterone
• Hormone replacement therapy, to ensure levels are optimised and safe

When is this test more useful than a basic testosterone check?

For some people, total testosterone alone doesn’t tell the full story. This applies especially to:

• Men with symptoms but normal total testosterone levels
• People with altered SHBG levels (e.g. due to thyroid issues, obesity, or liver conditions)
• Anyone on testosterone therapy, where monitoring free testosterone is essential
• Women being checked for PCOS or androgen excess, where precision is key

If you want to understand not just how much testosterone is in your body — but how much is actually doing its job — this test gives a much clearer answer.

Best time to take the test: Between 7am–10am, when testosterone levels are at their natural peak.
