Perimenopause Blood Test

Attend your appointment and one of our experienced nurses or phlebotomists will collect your blood sample. If your test also includes another sample, such as urine or stool, we will provide the necessary collection kit and clear instructions.

Results are typically available within Same day. Some individual markers may take longer if they require specialist laboratory processing. We will normally wait until the full profile is complete before issuing your reviewed results.

Fasting is not essential for most cholesterol tests. LDL and HDL cholesterol change very little after eating, although triglycerides can be more affected. You may therefore choose to fast for 8–12 hours for the clearest triglyceride result, but for most people either approach is acceptable. Plain water is fine.

Testosterone is usually best measured in the morning, ideally before 10:00 am, particularly when investigating possible testosterone deficiency. Fasting is not normally required unless another marker in the profile requires it.

The ideal timing depends on which hormones are being measured and why they are being tested. For many fertility and ovarian function assessments, blood tests are often recommended between days 2 and 5 of your menstrual cycle (where Day 1 is the first day of your period).

If your doctor has advised a specific day for testing, please follow their recommendation. If your menstrual cycles are irregular, you are postmenopausal, or you are taking hormonal contraception or hormone replacement therapy (HRT), your clinician may recommend a different approach.
