PCOS and PCOD: symptoms, key tests, and what to do next
PCOS, or polycystic ovary syndrome, is one of the most common hormonal conditions in women of reproductive age in India. It happens when the ovaries produce more androgens than usual, disrupting the normal cycle of egg release. The result is a cluster of symptoms - irregular periods, skin changes, and difficulty conceiving - that can feel confusing and isolating. The good news is that a small set of blood tests can give a clear picture of what is happening, and most women manage PCOS very well once they know what they are dealing with.

Common signs of PCOS
- Irregular, infrequent, or missed periods
- Unexplained weight gain, especially around the waist
- Acne on the face, chest, or back
- Excess hair on the face, chin, or upper lip
- Thinning hair on the scalp
- Difficulty getting pregnant
Which test tells you what
The LH to FSH ratio is a key marker in PCOS - when LH is significantly higher than FSH it suggests the ovaries are being driven to produce more androgens rather than releasing eggs normally. Prolactin is checked to rule out another hormonal condition that can mimic PCOS, since high prolactin causes very similar cycle disruptions. Total testosterone helps confirm androgen excess, which explains acne, facial hair, and scalp thinning. Fasting blood sugar reveals insulin resistance, which is present in many women with PCOS and makes both weight gain and long-term health risks worse.
When to get tested
Get tested if you have had irregular or skipped periods for three months or more, especially if you also notice acne, facial hair, or unexplained weight change. Women trying to conceive without success after six months of trying should not wait - early testing can identify a hormonal cause quickly. Testing is also sensible if a close female relative has been diagnosed with PCOS, since the condition runs in families. You do not need a referral to book these tests; a fasting sample in the morning gives the most accurate results.

Frequently asked questions
Can PCOS be diagnosed with a blood test alone?
Blood tests are a central part of diagnosis but are usually combined with an ultrasound scan and a review of your period history. No single test confirms PCOS on its own; the hormone panel helps build the picture and rules out other conditions like thyroid problems or high prolactin that can look similar.
Do I need to fast before the PCOS hormone tests?
Yes, a fasting sample of 8 to 10 hours is recommended, particularly because fasting blood sugar is included in the panel. Schedule your test for the morning and drink only water beforehand.
