Female Hormone Health & Balance Test

The storage form of thyroid hormone, mostly converted into T3 when needed. Most of your circulating thyroid hormone is in this T4 form.

The pituitary signal that tells your thyroid how hard to work. Counter-intuitively, high TSH usually means your thyroid is under-active (the brain is shouting at it), and low TSH often means it's over-active.

The active thyroid hormone, the one actually doing the work in your cells. T3 influences metabolic rate, energy, body temperature, mood and heart rate.

The main and most active oestrogen. In women it varies dramatically through the cycle, in pregnancy, and around menopause. In men it sits much lower but still has roles in bone, brain and cardiovascular health.

Works alongside FSH to regulate reproductive hormones. In women, LH triggers ovulation; in men, it signals the testes to produce testosterone.

A pituitary hormone that signals the ovaries or testes. In women it varies through the menstrual cycle and rises sharply around menopause; in men it sits in a steady range.

The protein that binds sex hormones in the blood. High SHBG can reduce the amount of biologically active testosterone, even when total testosterone looks normal.

The principal male sex hormone, also important in women at lower levels. Influences muscle mass, libido, mood, energy and bone density. Levels naturally peak in the morning, which is why we ask for a morning sample.

A pituitary hormone best known for its role in lactation, but it also influences reproductive function, libido and metabolism in everyone. Levels can rise temporarily with stress, exercise and sleep.

A calculated ratio of testosterone to SHBG, giving a quick picture of androgen activity. Particularly useful in women's hormone assessment.

The calculated amount of biologically active testosterone, derived from total testosterone, SHBG and albumin. Often more informative than total testosterone for symptoms.

The proportion of testosterone that isn't bound to carrier proteins, making it biologically active. A more nuanced view than total testosterone alone.
