Comprehensive PMOS (PCOS) 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.

Yes. As this profile includes insulin and/or C-peptide, we recommend fasting for 8–12 hours beforehand. Please drink plain water and take usual medication unless you have been specifically advised otherwise.

Fasting is not usually required, but timing is important because cortisol changes naturally throughout the day. Unless your clinician has requested a different time, a morning sample—typically between 8:00 am and 10:00 am—is usually preferred.

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.

An abnormal result does not necessarily confirm a diagnosis, but it may help guide further assessment.

This profile includes: Full Blood Count (FBC); Sodium; Potassium; Urea; Creatinine; Calcium; Chloride; Corrected Calcium; Total Protein; Albumin; Globulin; Alkaline Phosphatase (ALP); Total Bilirubin; Alanine Aminotransferase (ALT); Aspartate Aminotransferase (AST); Gamma-Glutamyl Transferase (GGT); Total Cholesterol; Triglycerides; VLDL Cholesterol; HDL Cholesterol; LDL Cholesterol; Total Cholesterol:HDL Ratio; HDL Percentage; Uric Acid; Phosphate; HbA1c; Serum Iron; Transferrin; Ferritin; Total Iron-Binding Capacity; High-Sensitivity C-Reactive Protein (hs-CRP); Free T4; Thyroid-Stimulating Hormone (TSH); Free T3; Thyroid Peroxidase Antibodies; Thyroglobulin Antibodies; Oestradiol; Progesterone; Luteinising Hormone (LH); Follicle-Stimulating Hormone (FSH); Testosterone; Free Androgen Index; Sex Hormone-Binding Globulin (SHBG); Prolactin; Insulin; Cortisol; DHEA-S; Vitamin D; Folate; Vitamin B12.

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.
