Total Testosterone

Women make a small amount of testosterone that supports energy, mood and muscle. Read with free testosterone and SHBG, it shows whether low drive or weight changes have an androgen side.

Free Testosterone

The portion of testosterone available to your tissues. In women, low levels are linked with low energy and libido, while higher levels can point to an androgen imbalance such as PCOS.

Progesterone

The hormone that rises after ovulation and balances estrogen. Low progesterone is linked with poor sleep, irregular cycles and mood changes, which can overlap with thyroid symptoms.

Estradiol

The main form of estrogen. It shifts across your cycle and falls around menopause, and low or fluctuating levels can cause fatigue and weight changes that look like thyroid symptoms.

Sex Hormone Binding Globulin (SHBG)

A protein that binds estrogen and testosterone. Thyroid hormone raises it, so a thyroid imbalance can change how much free hormone you have, linking both halves of this panel.

Thyroid Stimulating Hormone (TSH)

The pituitary's instruction to the thyroid. A high TSH suggests the thyroid is struggling to keep up, and thyroid problems are more common in women, especially around pregnancy and midlife.

Free Triiodothyronine (FT3)

The active thyroid hormone your cells respond to. When it runs low, energy and metabolism slow down, so it helps explain fatigue or weight gain alongside TSH and free T4.

Free Thyroxine (FT4)

The main hormone the thyroid releases, later converted into free T3. Read with TSH, it shows whether your thyroid's output matches what your body is asking for.

Follicle Stimulating Hormone (FSH)

The pituitary hormone that drives the ovaries. Rising FSH is one of the clearest signs of perimenopause, helping show whether symptoms are hormonal rather than thyroid-related.

Luteinizing Hormone (LH)

Another pituitary signal to the ovaries, and the one that triggers ovulation. Read with FSH, it helps show where you are in your cycle or in the transition to menopause.

DHEA-S

Made by the adrenal glands, DHEA-S is a building block for estrogen and testosterone in women. Lower levels are linked with low energy and libido, giving context to your sex hormone results here.
