If your periods keep arriving late, your skin refuses to clear, and the scale creeps up despite your best efforts, a PCOS ultrasound in Thane paired with a few hormone tests can give you a clear answer. Polycystic ovary syndrome affects roughly one in five Indian women of reproductive age, yet many wait years for a diagnosis because the symptoms are dismissed as stress, diet or “just hormones”.
Getting the right scan and blood work early changes the picture. PCOS cannot be cured, but it can be managed very well when it is caught before it affects fertility, blood sugar and heart health. Here is how diagnosis actually works, and what to expect when you walk into a diagnostic centre.
What PCOS really is — and why it is so often missed
PCOS is a hormonal and metabolic condition in which the ovaries produce higher-than-usual levels of androgens, the so-called male hormones. This disrupts ovulation, which is why periods become irregular, scanty or absent.
The name is misleading. Many women with PCOS do not have large “cysts” at all; what the scan shows are numerous small follicles that have stalled before releasing an egg. Equally, some women with ovaries that look polycystic have no symptoms and no PCOS.
This is why doctors never diagnose PCOS from one test. They look for a pattern across your symptoms, your hormone levels and your ultrasound.
Early symptoms of PCOS that deserve a check-up
Cycles longer than 35 days, or fewer than eight periods a year, are the most reliable red flag. Others tend to cluster around them:
Persistent acne on the jawline and chin, excess hair growth on the face, chest or abdomen, thinning hair on the scalp, weight gain concentrated around the waist, darkened skin patches on the neck or underarms, and difficulty conceiving after a year of trying.
Teenagers and women in their twenties are often told to wait it out. If two or more of these signs persist for three months, it is reasonable to ask for a proper evaluation instead.
The PCOS ultrasound: what it shows and how it is done
A pelvic ultrasound is the imaging backbone of PCOS diagnosis. Radiologists look at the number and size of follicles in each ovary, the ovarian volume, and the thickness of the uterine lining, which can become unusually thick when periods are infrequent.
The widely used Rotterdam criteria require two of three findings: irregular or absent ovulation, signs of high androgens (clinical or on blood tests), and polycystic-appearing ovaries on ultrasound. Newer guidelines also consider a higher follicle count per ovary on modern high-resolution machines.
For unmarried women and teenagers, a transabdominal scan is done over the lower abdomen with a comfortably full bladder. For married women, a transvaginal scan gives sharper detail and takes only a few minutes. Neither is painful, and your comfort and privacy come first. You can see what we offer under our sonography and diagnostic services.
Timing matters too. Doctors often prefer the scan between day 2 and day 5 of your cycle, so mention this when booking.
Blood tests that complete the PCOS picture
An ultrasound alone is never enough. A typical PCOS panel includes LH and FSH (their ratio can be reversed in PCOS), testosterone, AMH (anti-Müllerian hormone, which is often raised), prolactin and thyroid function tests, since an underactive thyroid can mimic PCOS.
Because PCOS is closely tied to insulin resistance, your doctor may also advise fasting glucose, fasting insulin, HbA1c and a lipid profile. Up to half of women with PCOS develop prediabetes or type 2 diabetes by their forties, so catching the metabolic side early is just as important as treating periods.
Most of these tests are drawn in the early part of your cycle and some need fasting, so confirm the instructions before you arrive.

A note on lifestyle: even a modest 5 to 10 percent weight loss, regular exercise and a diet lower in refined carbohydrates can restore ovulation in many women. A confirmed diagnosis simply gives your doctor the right starting point.
Frequently asked questions
Can PCOS be diagnosed by ultrasound alone?
No. An ultrasound showing polycystic-appearing ovaries supports the diagnosis, but doctors also need irregular periods or high androgen signs, and they rule out thyroid and prolactin disorders with blood tests.
Do I need an empty or full bladder for a PCOS ultrasound?
For a transabdominal scan you need a comfortably full bladder, so drink about four glasses of water an hour before. A transvaginal scan is done with an empty bladder.
Which blood tests are done for PCOS?
The usual panel includes LH, FSH, testosterone, AMH, prolactin and TSH, often with fasting glucose, insulin and a lipid profile to check for insulin resistance.
