What we test

Made by the small, growing follicles in your ovaries. AMH estimates your ovarian reserve (roughly how many eggs you have left) and helps predict how you may respond to egg freezing or IVF. It doesn’t measure egg quality.

The main form of estrogen in your reproductive years. It rises as follicles grow and helps build the uterine lining.

Released by the pituitary gland to signal your ovaries to grow follicles. Higher FSH early in your cycle can be a sign of lower ovarian reserve.

Surges mid-cycle to trigger ovulation. The balance between LH and FSH can point to conditions like PCOS.

Rises after ovulation to prepare the uterine lining for pregnancy. Levels in the second half of your cycle help confirm that you ovulated.

The hormone behind breast-milk production. High levels outside pregnancy can disrupt ovulation and cause irregular periods.

All the testosterone in your blood. Women make it in small amounts; higher levels are associated with PCOS.

The share of testosterone that is unbound and available for your body to use. Often a clearer signal of excess androgens than total testosterone.

A protein that carries testosterone and estrogen in your blood. Low SHBG leaves more free testosterone and is linked to insulin resistance and PCOS.

Tells your thyroid how hard to work. The main screen for an under- or overactive thyroid, both of which can affect your cycle and fertility.

The main hormone your thyroid makes. Read alongside TSH to see how well your thyroid is working.

The active form of thyroid hormone, which drives your metabolism and energy.

Your average blood sugar over the past 2–3 months. Screens for prediabetes and diabetes, which can affect ovulation and pregnancy.

The hormone that moves sugar from your blood into your cells. High insulin can signal insulin resistance, a common driver of PCOS.

The cholesterol that can build up in blood vessel walls. A key marker of heart health.

Compares your LDL cholesterol with ApoB, a count of the particles that carry it. A low ratio suggests many small, dense particles, which are linked to higher heart risk.

A type of fat in your blood that rises with excess sugar, refined carbs and alcohol. High levels are linked to insulin resistance.

A simple marker of insulin resistance and heart health. Lower is generally better.

Measures low-grade inflammation in your body, which is linked to heart health, metabolic health and some reproductive conditions.

Your body’s iron stores. Low ferritin is common, can cause fatigue and hair loss, and matters for a healthy pregnancy.

The protein in red blood cells that carries oxygen. Low levels can mean anemia.

The share of your blood made up of red blood cells. Read with hemoglobin to check for anemia.

An enzyme from your liver and bones, used to check liver and bone health.

A liver enzyme that rises when the liver is under stress, including from alcohol and some medications.

The main protein your liver makes. Reflects liver function and nutrition.

A waste product filtered by your kidneys, used to check how well they are working.

Supports bone, immune and hormone health. Low levels are common and have been linked to poorer fertility outcomes.
