Female Metabolic & Hormonal Health Panel

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 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 combined amount of albumin and globulin in your blood. It's a broad picture of protein status, used together with albumin and globulin to spot imbalances.

Proteins that play a major role in immunity, clotting and transport. Calculated by subtracting albumin from total protein. Patterns here can signal immune or inflammatory activity.

The most abundant protein made by your liver. It transports hormones and nutrients around the body and helps regulate fluid balance. Low albumin can reflect liver, kidney, gut or nutritional factors.

A yellow pigment made when old red blood cells are broken down. Slightly raised bilirubin is often a harmless inherited pattern (Gilbert's syndrome); larger elevations can reflect liver or red blood cell processes.

A liver enzyme that leaks into the blood when liver cells are stressed. Mildly raised ALT is common after heavy training, recent alcohol, certain medications, or fatty changes in the liver. Persistently high ALT is worth discussing with a GP.

A liver enzyme particularly sensitive to alcohol intake and certain medications. Useful for understanding the source when other liver markers are raised.

An enzyme involved in both liver and bone activity. Levels naturally vary with age (higher in growing teens, post-fracture healing) and during pregnancy, as well as with liver function.

An enzyme that leaks into your blood when liver cells are stressed or damaged. Often looked at alongside ALT to give a clearer picture of liver health. Heavy exercise can also raise it temporarily.

An estimate of how efficiently your kidneys filter blood, calculated from your creatinine. Higher is generally better. It's the single most-used indicator of overall kidney functio n.

Another waste product cleared by the kidneys, this one from protein breakdown. It's affected by hydration, protein intake and kidney function.

A waste product your muscles produce that's filtered out by your kidneys. Levels can shift with muscle mass, hydration status and protein intake, so very muscular people often sit slightly higher than the population average.

Your main stress and energy hormone, produced by your adrenal glands. It follows a strong daily rhythm: highest in the morning (which is why we ask for a morning sample) and lowest at night. Affected by sleep, training, work stress and caffeine.

Your average blood sugar level over the past 8-12 weeks, expressed as a percentage. Often called your "glucose memory" because, unlike a single glucose reading, it can't be gamed by a recent meal or fast.

The same measurement in mmol/mol, the unit the NHS and UK clinicians use. We show both so you can compare to NHS or older test results easily.

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.

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.

Your body's stored iron, the long-term iron savings account. Low ferritin is the earliest sign of iron deficiency, often appearing before iron itself drops or anaemia develops. Common in women with heavy periods, athletes, and people on plant-based diets.

Works alongside B12 to build red blood cells and support DNA repair. Particularly important for women of reproductive age. Influenced by diet, certain medications, and alcohol intake.

Essential for energy production, nerve function, and red blood cell formation. Found almost exclusively in animal products, so vegans and vegetarians need to supplement. Low B12 can present as fatigue, brain fog or tingling.
