Polycystic ovary syndrome

Book Now

Polycystic ovary syndrome (PCOS) is one of the most common hormonal conditions affecting women of reproductive age, yet it often goes undiagnosed for years. Symptoms can be wide-ranging — irregular periods, unexplained weight gain, acne, excess hair growth, hair thinning, and difficulty conceiving — and blood tests are a key part of confirming the diagnosis and understanding the hormonal picture.

Tamar Health offers two PCOS blood test profiles. The standard screen covers the core hormonal, metabolic, and thyroid markers; the extended profile adds AMH (anti-Müllerian hormone), which reflects ovarian reserve and is often used in the assessment of PCOS alongside ultrasound. Your sample is processed by Nationwide Pathology, a UKAS-accredited UK laboratory, with results returned the next working day.

From £135 All-inclusive — phlebotomy fee included
Next day Results returned by email
No GP referral Book direct — appointment same week
Prices are all-inclusive. The phlebotomy appointment fee is built into the cost of each profile — there is no separate charge on top.

Choose your profile

Both profiles cover the essential hormonal and metabolic markers used in PCOS assessment. The extended profile adds AMH, which is particularly useful if you’re also thinking about fertility or want a fuller picture of your ovarian function.

PCOS Screen £135 Core hormonal & metabolic assessment
  • LH & FSH — pituitary hormones; LH:FSH ratio is a key PCOS marker
  • Testosterone (Total) — androgen excess
  • Free Androgen Index (FAI) — bioavailable testosterone
  • SHBG — sex hormone binding globulin
  • Prolactin — can mimic PCOS symptoms if elevated
  • DHEA-S — adrenal androgen marker
  • Oestradiol — oestrogen level
  • Thyroid Function (TSH, Free T4) — to exclude thyroid causes
  • Fasting Glucose & Insulin — insulin resistance screening
  • HbA1c — longer-term glucose marker
  • Full Blood Count — general health baseline
PCOS Screen + AMH £245 Adds anti-Müllerian hormone (ovarian reserve)
  • Everything in PCOS Screen, plus:
  • AMH (Anti-Müllerian Hormone) — a marker of ovarian reserve; typically elevated in PCOS and used alongside ultrasound in diagnosis

AMH is processed separately. Results are returned with the standard profile on the next working day.

Timing matters for some markers. LH, FSH, and oestradiol are ideally tested on day 2–5 of your menstrual cycle for the most meaningful results. If your cycles are irregular or absent, testing can be done at any time — please mention this when booking and we can advise.

What the results can tell you

A PCOS diagnosis is made using clinical criteria — blood tests are one part of the picture, alongside symptoms and (often) a pelvic ultrasound. However, blood tests are essential for:

  • Confirming androgen excess — elevated testosterone or FAI is present in the majority of women with PCOS and helps confirm the diagnosis
  • Checking the LH:FSH ratio — a ratio above 2:1 is a classic feature of PCOS, though not universal
  • Ruling out other causes — thyroid disorders and elevated prolactin can cause very similar symptoms and must be excluded
  • Assessing insulin resistance — present in a significant proportion of women with PCOS and important for long-term health management
  • Evaluating ovarian reserve (AMH) — AMH is typically elevated in PCOS; the result is also used in fertility planning
Clinical review included. Once your results are ready, a clinician reviews them and emails you a clear summary. If anything needs urgent attention, we contact you the same day. A follow-up appointment is available to discuss results in more detail, explore diagnosis, or talk through next steps.
