If your periods are irregular, you’ve been gaining weight despite eating right, or you’re struggling with acne and excessive hair growth, your doctor may suspect PCOS — Polycystic Ovary Syndrome. Getting a PCOS test in Thane can give you clear, actionable answers. But here’s what most women don’t realise: diagnosing PCOS isn’t a single test. It requires a carefully chosen combination of blood work and a pelvic sonography to see the complete picture.
At Kaizen Diagnostic Centre in Kalwa, Thane, we perform the full range of PCOS-related diagnostics — from hormonal blood panels to high-resolution pelvic ultrasound — so your gynaecologist gets everything needed to confirm or rule out the condition without multiple trips to different centres.
What Is PCOS and Why Early Diagnosis Matters
PCOS affects an estimated 1 in 5 Indian women of reproductive age, making it one of the most common hormonal disorders in the country. Despite how prevalent it is, many women go years without a diagnosis — often attributing symptoms to stress, lifestyle changes, or “just irregular periods.”
Left unaddressed, PCOS raises the long-term risk of Type 2 diabetes, insulin resistance, infertility, cardiovascular disease, and endometrial abnormalities. The good news: when caught early through the right diagnostic tests, PCOS is highly manageable with the right clinical guidance.
The diagnosis rests on what’s called the Rotterdam Criteria — a globally accepted framework requiring at least 2 of these 3 findings:
- Irregular or absent menstrual cycles (oligomenorrhoea or amenorrhoea)
- Clinical or biochemical signs of excess androgens (male hormones)
- Polycystic ovaries visible on pelvic ultrasound
This is precisely why your workup must include both blood tests and an ultrasound — neither alone is sufficient for an accurate diagnosis.
PCOS Blood Tests: What Gets Tested and Why
A targeted PCOS hormone panel checks multiple markers across reproductive and metabolic health. Here’s what each test reveals and why it matters:
LH and FSH (Luteinizing Hormone & Follicle Stimulating Hormone)
In women with PCOS, the LH:FSH ratio is often elevated — sometimes 2:1 or 3:1 — whereas the normal ratio is approximately 1:1. This hormonal imbalance disrupts ovulation. This test is most accurate on Day 2 or Day 3 of your menstrual cycle.
Total and Free Testosterone
Elevated androgens are one of the hallmarks of PCOS. They explain symptoms like facial hair (hirsutism), persistent acne, and hair thinning from the scalp. Free testosterone is the more sensitive marker, reflecting what’s biologically active in the body rather than protein-bound and inactive.
AMH (Anti-Müllerian Hormone)
AMH levels are significantly elevated in women with PCOS — often 2 to 4 times above the normal range. This hormone reflects the total antral follicle count in the ovaries. A high AMH is increasingly used as a reliable supporting marker for PCOS and can be tested on any day of the cycle.
Fasting Insulin and Glucose (Insulin Resistance Panel)
Up to 70% of women with PCOS have insulin resistance — even when fasting blood sugar appears normal. Measuring fasting insulin alongside fasting glucose, and calculating the HOMA-IR index, uncovers this hidden driver of the condition. This panel directly shapes treatment decisions around diet, medication, and lifestyle.
Thyroid Function Test (TSH, T3, T4)
Thyroid disorders can mimic or significantly worsen PCOS symptoms — including irregular periods and unexplained weight gain. A thyroid panel is always ordered alongside PCOS testing to rule out hypothyroidism as a contributing factor. Our diagnostic services include comprehensive thyroid panels with fast turnaround.
Prolactin
Elevated prolactin can suppress ovulation and cause cycle irregularities — symptoms that overlap directly with PCOS. Testing prolactin levels helps your clinician rule out hyperprolactinaemia as the primary cause before confirming a PCOS diagnosis.
PCOS Sonography: What the Ultrasound Is Actually Looking For
A pelvic ultrasound — ideally a transvaginal sonography for the clearest resolution — examines the ovaries and uterus directly. Our sonographers look for the following:
- Follicle count: 20 or more small follicles (2–9 mm in diameter) in either ovary is the updated PCOS threshold using modern high-resolution probes. The classic criterion was 12 follicles; newer guidelines have raised this bar.
- Ovarian volume: An ovarian volume greater than 10 mL is considered enlarged — an independent diagnostic marker for PCOS.
- Endometrial thickness: The uterine lining is assessed, as unopposed estrogen in PCOS can cause the endometrium to thicken progressively — a finding that requires monitoring.
- Structural findings: The scan also screens for fibroids, endometrial polyps, or anatomical abnormalities that may independently explain menstrual irregularities.
When Should You Get Tested for PCOS?
Don’t wait for symptoms to escalate before seeking a diagnosis. Consider a PCOS workup if you experience any of the following:
- Periods that occur fewer than 8 times a year, or cycles consistently longer than 35 days
- Unexplained weight gain, particularly around the abdomen
- Facial or body hair growth on the chin, upper lip, or chest
- Hair thinning or shedding from the scalp
- Persistent acne that doesn’t respond to standard treatment after your teenage years
- Difficulty conceiving after 6–12 months of trying
- Darkened, velvety skin in skin folds (acanthosis nigricans) — a visible sign of insulin resistance
Adolescents are not exempt. PCOS can present as early as the first few years after menstruation begins — though diagnosing teenagers requires careful interpretation, since irregular cycles in the first 2 years post-menarche can be normal.

Frequently Asked Questions About PCOS Testing
Which blood test confirms PCOS?
No single blood test confirms PCOS on its own. Diagnosis requires a combination of tests — including LH, FSH, free testosterone, AMH, fasting insulin, thyroid function, and prolactin — interpreted together with a pelvic ultrasound. Your doctor uses the Rotterdam Criteria to assess all findings holistically before making a diagnosis.
On which day of the cycle should I get PCOS blood tests done?
Hormone tests like LH, FSH, and prolactin are most accurate on Day 2 or Day 3 of your menstrual cycle (Day 1 being the first day of bleeding). AMH and testosterone can be tested on any day. Your diagnostic centre will advise you on optimal timing when you book your PCOS panel.
Can I have PCOS if my ultrasound is normal?
Yes. Under the Rotterdam Criteria, PCOS can be diagnosed without polycystic ovaries on ultrasound — if you have irregular periods plus elevated androgens confirmed by blood tests. Conversely, polycystic-appearing ovaries on ultrasound alone do not constitute a PCOS diagnosis. This is why a complete panel combining blood work and imaging is always recommended.
