Most Indian PCOS workups stop at a pelvic ultrasound and a TSH. The diagnosis gets stamped, Krimson 35 gets prescribed, and the actual disease — insulin resistance, adrenal subtype, or a thyroid mimic — never gets seen. This article is the full diagnostic panel by name, what each test means, where to get it cheapest, and the printable script to take into the appointment.
Short answer: the full PCOS diagnostic workup needs 14 labs plus a transvaginal ultrasound, runs Rs 6,500 to 14,000 at private labs (Rs 500 to 2,000 at government tertiary hospitals), and most Indian gynaecologists order fewer than half by default. Demand the rest by name.
For the broader picture — symptoms, the 4 subtypes, diet, treatment, fertility — start with the PCOS pillar guide. This article zooms in on diagnostics only.
Why the Standard Indian Workup Is Incomplete
The default PCOS panel at a typical Indian gynaecology clinic is:
- Pelvic ultrasound (often transabdominal, not transvaginal)
- TSH
- Sometimes LH and FSH
- Sometimes total testosterone
- Sometimes fasting glucose and HbA1c
That panel can confirm an obvious case. It cannot:
- Rule out non-classical congenital adrenal hyperplasia (which mimics PCOS in 5 to 9 percent of South Asian women)
- Detect lean PCOS with insulin resistance and normal fasting glucose
- Distinguish ovarian from adrenal PCOS (changes treatment)
- Quantify free androgen burden (total testosterone misses 30 to 40 percent of high-androgen cases when SHBG is low)
- Catch the vitamin D deficiency that is universal in Indian PCOS and worsens insulin resistance
The international standard (Rotterdam 2003, Monash/ESHRE 2018 and 2023 international guideline) and the Endocrine Society Clinical Practice Guideline require more. The list below is what good endocrinology practice looks like — at AIIMS Delhi, the Sanjay Gandhi PGI, Singapore General, Cleveland Clinic. Use it as your reference.
The Full 14-Test PCOS Panel (Plus Imaging)
Cycle timing
Schedule blood draws on day 2 or 3 of your period if you are still menstruating, between 8 am and 10 am, fasting for 10 to 12 hours. If you are amenorrheic for more than 60 days, take blood at any time but note this on the lab slip — it changes the interpretation of LH, FSH and progesterone.
Group 1 — Androgens
| Test | Why | What an abnormal result means | Private cost (Rs) |
|---|---|---|---|
| Total testosterone | Primary androgen | Elevated = ovarian or adrenal androgen excess | 350 to 600 |
| Free testosterone or Free Androgen Index | Bioactive fraction | Better correlation with clinical androgen symptoms than total | 600 to 1,200 |
| DHEAS | Adrenal androgen | Elevated = adrenal subtype PCOS or NCAH | 500 to 900 |
| SHBG (Sex Hormone Binding Globulin) | Carrier protein | Low SHBG = high free androgens even if total testosterone is normal | 500 to 900 |
| 17-hydroxyprogesterone | Rules out NCAH | Above 2 ng/ml on day 2-3 warrants ACTH stim test | 800 to 1,200 |
The single most-skipped test in India is 17-OHP. Skipping it means 5 to 9 percent of women diagnosed with PCOS actually have non-classical congenital adrenal hyperplasia, which responds to low-dose dexamethasone or hydrocortisone, not metformin or OCPs. The mistreatment can last a decade.
Group 2 — Reproductive hormones
| Test | Why | What an abnormal result means | Private cost (Rs) |
|---|---|---|---|
| LH (Luteinising Hormone) | Ovarian signalling | High LH or high LH:FSH ratio is supportive but NOT diagnostic | 300 to 500 |
| FSH (Follicle Stimulating Hormone) | Pair with LH | Elevated FSH suggests low ovarian reserve, not PCOS | 300 to 500 |
| Prolactin | Rules out hyperprolactinaemia | Above 25 ng/ml warrants medication review and possibly pituitary imaging | 300 to 600 |
| TSH | Rules out thyroid mimic | Above 4.0 mIU/L = subclinical or overt hypothyroidism | 200 to 500 |
| AMH (optional) | Ovarian reserve | Above 5 ng/ml suggestive of PCOS but not diagnostic alone | 1,400 to 2,200 |
The LH:FSH ratio above 2:1 is folklore — the Endocrine Society dropped it as a diagnostic criterion over a decade ago. Indian labs and gynaecologists still flag it as if it matters. It does not, on its own.
Group 3 — Metabolic
| Test | Why | What an abnormal result means | Private cost (Rs) |
|---|---|---|---|
| Fasting insulin | Insulin resistance | Above 10 mIU/ml suggests insulin resistance | 350 to 600 |
| Fasting glucose | Pair with insulin to compute HOMA-IR | Above 100 mg/dl = impaired fasting glucose | 100 to 200 |
| HOMA-IR (calculated) | Insulin resistance index | Above 2.0 to 2.5 = insulin resistant in Indians | (calculation) |
| HbA1c | Average 3-month glucose | 5.7 to 6.4 percent = prediabetes; above 6.5 = diabetes | 350 to 600 |
| 75g OGTT with insulin at 0 and 120 min | Gold standard for insulin resistance | 2-hour insulin above 60 mIU/ml = insulin resistant; 2-hour glucose above 140 = impaired tolerance | 1,200 to 2,000 |
| Lipid profile | Cardiovascular risk | High triglycerides and low HDL are hallmark of insulin-resistant PCOS | 400 to 700 |
The 2-hour OGTT with insulin is the most useful single test in the entire panel and the one most likely to be missed. If you have any central weight gain, acanthosis nigricans, family history of type 2 diabetes, or recurrent miscarriage, ask for it explicitly. Most Indian labs run a 75g OGTT for glucose only (Rs 350) — you need to specifically ask for the insulin assays at 0 and 120 minutes.
For wider context on glycaemic markers and Indian-population reference ranges, our HbA1c reference guide and the diabetes testing schedule cover the same labs from the diabetes vertical.
Group 4 — Nutritional and micronutrient
| Test | Why | What an abnormal result means | Private cost (Rs) |
|---|---|---|---|
| Vitamin D (25-OH) | Universal deficiency in Indians; worsens insulin resistance | Below 30 ng/ml = deficient; target 50 to 70 | 700 to 1,200 |
| Vitamin B12 | Often low in vegetarians and on metformin | Below 300 pg/ml = supplement; below 200 = deficient | 500 to 900 |
Both are cheap, treatable, and routinely missed.
Group 5 — Imaging
Transvaginal pelvic ultrasound — Rs 1,500 to 2,500 at private centres, Rs 100 to 400 at government hospitals. Look for:
- Follicle count per ovary (20 or more = polycystic morphology per current Rotterdam threshold)
- Ovarian volume (above 10 ml = polycystic morphology)
- Endometrial thickness (above 7 to 8 mm in an anovulatory woman warrants progesterone withdrawal to prevent hyperplasia)
If you are not sexually active or are an adolescent, transabdominal ultrasound is used despite lower follicle-count accuracy.
Total Cost — Private vs Government
| Pathway | Cost range | Wait time | Quality |
|---|---|---|---|
| Thyrocare bundled PCOS panel (incomplete — add 17-OHP, OGTT-insulin separately) | Rs 2,400 to 5,000 | Same day | Adequate if you add the missing tests |
| Dr Lal Pathlabs full panel | Rs 7,500 to 11,000 | Same day | Good |
| Metropolis full panel | Rs 8,000 to 12,000 | Same day | Good |
| SRL full panel | Rs 7,000 to 10,500 | Same day | Good |
| Apollo Diagnostics bundled PCOS panel | Rs 6,800 to 8,500 | Same day | Branded, more inclusive |
| Hospital-based diagnostics (Apollo, Fortis, Manipal in-house) | Rs 10,000 to 14,000 | Same day | Highest |
| Government tertiary hospital (AIIMS, PGIMER, JIPMER, KGMU, NIMS) | Rs 500 to 2,000 | 4 to 8 weeks first OPD | Highest clinical rigor |
The cost gap is real, but the wait gap is also real. Most working professionals do the workup privately and use government hospitals for second opinions or complex cases. NRIs visiting India for a workup can do the full panel in 48 hours at any of the major chains.
Government Hospital PCOS Pathways (Specific Clinics)
These are the dedicated PCOS or endocrinology clinics in major government tertiary hospitals as of 2026. Show up on the listed OPD day, register at the morning counter, expect a 4 to 8 hour visit, and budget two or three follow-ups for the full workup to complete.
- AIIMS Delhi — Department of Endocrinology and Metabolism, PCOS clinic typically on Wednesday OPD
- PGIMER Chandigarh — Department of Endocrinology, dedicated PCOS clinic
- KGMU Lucknow — Endocrinology OPD with PCOS focus
- Sanjay Gandhi PGI Lucknow — Endocrinology consultation
- JIPMER Puducherry — Endocrinology OPD with PCOS expertise
- NIMS Hyderabad — Endocrinology OPD
- CMC Vellore — Department of Endocrinology, Diabetes and Metabolism (Christian Medical College — not strictly government but heavily subsidised)
- Seth GS Medical College and KEM Hospital Mumbai — Endocrinology OPD
- GMCH Chandigarh / SMS Jaipur / IPGMER Kolkata — State medical college endocrinology OPDs
For specific guidance on navigating walk-in OPDs at large institutional hospitals, the NIMHANS Bengaluru walk-in guide follows the same registration and follow-up pattern (the article is mental health focused but the OPD logistics translate).
How to Interpret Your Results — Quick Reference
| Pattern | What it suggests |
|---|---|
| High total testosterone + high DHEAS + normal 17-OHP | Mixed ovarian and adrenal PCOS |
| Normal total testosterone + low SHBG + high free testosterone | Insulin-resistant PCOS with biochemical hyperandrogenism masked by SHBG suppression |
| High DHEAS dominant, normal testosterone | Adrenal subtype PCOS |
| 17-OHP above 2 ng/ml on day 2-3 | Non-classical CAH — needs ACTH stim test, NOT typical PCOS treatment |
| TSH above 4.0 with normal androgens | Thyroid is the primary driver — treat thyroid first |
| Prolactin above 25 ng/ml | Hyperprolactinaemia — pituitary imaging if persistent |
| Fasting insulin above 10, HOMA-IR above 2.5 | Insulin resistance present even if glucose is normal |
| 2-hour OGTT glucose above 140 | Impaired glucose tolerance — prediabetic trajectory |
| AMH above 5 with anovulation | Supportive of PCOS |
| Vitamin D below 30 | Deficient — supplement to 50 to 70 ng/ml |
| LH:FSH above 2:1 alone | Not diagnostic — ignore as standalone criterion |
For the metabolic side specifically — what a HOMA-IR of 3.2 means, how to interpret the OGTT curve, what insulin-sensitising interventions to start — see the PCOS pillar and our diabetes pillar.

The Script to Take into Your Appointment
Print this. Hand it across the table. Watch what happens.
“I am here to be evaluated for polycystic ovary syndrome using the Rotterdam criteria. Please order the following 14 tests plus a transvaginal pelvic ultrasound, before initiating any treatment:
- Total testosterone
- Free testosterone or Free Androgen Index
- SHBG
- DHEAS
- 17-hydroxyprogesterone (cycle day 2 or 3)
- LH and FSH (cycle day 2 or 3)
- Prolactin
- TSH
- AMH (optional, for fertility context)
- Fasting insulin and fasting glucose, with HOMA-IR calculation
- HbA1c
- 75g oral glucose tolerance test with insulin assays at 0 and 120 minutes
- Fasting lipid profile
- Vitamin D (25-OH) and Vitamin B12
If any of these tests are not standard at this clinic, please note which ones are being deferred and why, in writing, so I can complete them externally. I would also like the ultrasound to be transvaginal where appropriate, with follicle count and ovarian volume documented.
If treatment is recommended, please specify which Rotterdam criterion or criteria are met, and which PCOS subtype is most consistent with my results.”
This script does three things. It signals that you have done your homework, which changes how seriously you are taken. It puts the burden of justification on the clinician for any test that is skipped. And it locks in your right to seek the same workup elsewhere without paying twice.
What to Skip — Tests That Are Marketed but Not Helpful
- AMH as a standalone PCOS test — useful for fertility planning, not diagnostic on its own
- Random testosterone without timing — much more meaningful on day 2-3 of cycle
- Insulin resistance “DNA panels” marketed by some Indian diagnostic chains — overpriced and clinically unhelpful
- “PCOS genetic test” packages — no clinically actionable result
- Repeat ultrasound every 3 months — once the polycystic morphology is documented, repeat scans rarely change management
- Hair mineral analysis for PCOS — pseudoscience
- Generic “hormonal balance” panels at wellness chains that bundle 30 tests including some unrelated to PCOS — pay only for the 14 listed above
Special Cases
Teenagers (13 to 18 years)
Diagnosis should not be made within 2 to 3 years of menarche because irregular cycles are normal during this period. The international guideline specifically advises against locking in PCOS labels in adolescents. Symptom management (acne, hirsutism) is reasonable; the formal label can wait. Transvaginal ultrasound is not used; transabdominal is. AMH is not a useful marker in adolescents either.
Women on hormonal contraception
Combined OCPs and progestin-only pills suppress most PCOS markers. To diagnose PCOS accurately while on the pill, you need to stop for 3 months and re-test, or rely on pre-pill records and clinical features. Many Indian women have been on the pill for 5 to 10 years and have no baseline data; in that case, prioritise the metabolic panel (which is not affected by OCPs) and reassess hormones after a 3-month washout.
Post-pill amenorrhoea
If you stopped a long-term OCP 3 to 9 months ago and your period has not returned, the picture may be “post-pill PCOS” rather than a chronic case. The same tests apply, but be aware that the syndrome may self-resolve over 12 to 18 months. Treat conservatively (inositol, lifestyle) before locking in long-term medication.
Pregnancy planning
Add a thyroid panel with free T4 and anti-TPO antibodies if you are planning to conceive within 12 months — PCOS and autoimmune thyroid disease overlap frequently, and pre-conception TSH should be below 2.5. For specific Indian guidance on thyroid in pregnancy, our thyroid in pregnancy guide covers the reference ranges and risks.
