What is the FSH Blood Test?

FSH is produced in the pituitary gland and plays a role in controlling the menstrual cycle, egg production in the ovaries, and reproductive system function. An FSH Blood Test, alongside symptom review, is used to assess menopause.

Do I need to fast for an FSH Blood Test?

No fasting is required. However, women should ideally take the test on day 3 of their menstrual cycle if still having periods. Biotin supplements should be avoided for 72 hours before the test.

What happens if my FSH Blood Test shows a problem?

Results are colour-flagged as green, amber, or red. Amber or red results may indicate an imbalance. Bluecrest provides guidance on lifestyle changes, monitoring, or referral to a doctor. Critical results trigger immediate contact.

Who should have an FSH Blood Test?

The FSH Blood Test is recommended for women with irregular or absent periods, symptoms of menopause or perimenopause, or suspected ovarian failure.

Does alcohol affect an FSH Blood Test?

Yes. Alcohol can increase oestrogen levels, which affects FSH readings. Avoid alcohol before the test to obtain the most accurate results.

How do I prepare for the test?

Full preparation instructions are provided when you book. Women should schedule testing on day 3 of their cycle if still menstruating, and avoid biotin supplements for 72 hours prior.

Private FSH Blood Test (Follicle-Stimulating Hormone)

Check your hormone levels with a private FSH Blood Test. Enjoy fast results and clear insights to help you understand fertility and menopause changes.

Because your health matters

Check your reproductive hormone levels quickly and accurately with a private FSH Blood Test. This simple test provides valuable insight into fertility health, pituitary function and menopause progression.

Why FSH matters

Follicle-Stimulating Hormone (FSH) is produced by the pituitary gland and regulates the reproductive system. In women, it supports egg development and stimulates oestrogen production. As ovarian function declines with age, FSH levels naturally rise - making elevated levels a common indicator of menopause.

Monitoring FSH can help identify concerns such as reduced ovarian function, ovarian failure or the onset of menopause. It can also support wider investigations into pituitary or hypothalamic disorders.

A private FSH Blood Test offers a clear picture of your reproductive hormone levels and can be added to any full body health check.
