The problem

PCOS looks different on your blood

Irregular periods. Cystic acne. Hair loss. weight gain despite diet and exercise. Exhaustion. These are signs your hormones are dysregulated — but standard bloodwork misses it. Most women are dismissed as "normal" when actually their insulin is spiking, androgens are elevated, or thyroid function is suppressed.

Quick Answer

PCOS affects 1 in 5 Indian women but most get diagnosed by ultrasound alone. Proper diagnosis requires bloodwork: testosterone, DHEA-S, insulin, SHBG, AMH, thyroid panel, and cortisol. Treatment depends on your PCOS phenotype — there are 4 distinct types, each needing a different approach.

The science

Markers we read for PCOS

These biomarkers reveal the root causes — and what actually works to fix them.

Fasting Insulin
Insulin resistance drives 70% of PCOS cases. Elevated levels suppress ovulation and worsen acne.
DHEA-S
Adrenal androgen causing cystic acne and facial/body hair growth. Often overlooked in standard testing.
Free Testosterone
Elevated in most PCOS patients. Drives hirsutism, acne, and ovulatory dysfunction.
AMH
Anti-müllerian hormone shows ovarian reserve and cyst burden. Predicts fertility outcomes.
TSH + Free T4
Thyroid dysfunction mimics PCOS symptoms. Hypothyroidism worsens insulin resistance.
HbA1c
Metabolic risk marker. 40% of PCOS women develop diabetes by age 40 without intervention.

PCOS Biomarker Panel

Complete biomarker reference for PCOS diagnosis and treatment monitoring

Biomarker What It Tests Why It Matters for PCOS Optimal Range
Total Testosterone Ovarian androgen production Elevated in 70% of PCOS cases; drives acne, hair loss, ovulation issues <0.7 ng/mL women
Free Testosterone Unbound, active androgen Better indicator of symptomatic hyperandrogenism than total testosterone alone 0.0–4.2 pg/mL
DHEA-S Adrenal androgen reserve Elevated in non-classic PCOS; identifies adrenal dysfunction; affects acne severity 35–430 µg/dL (age-dependent)
Fasting Insulin Basal insulin levels at rest Insulin resistance drives 70% of PCOS; >12 mIU/L indicates problem; key for treatment 2–12 mIU/L
HOMA-IR Insulin resistance index (glucose × insulin) Better than fasting insulin alone; HOMA-IR >2.0 = insulin resistance confirmed <2.0
SHBG Sex hormone binding globulin Insulin suppresses SHBG; low SHBG = more free (active) testosterone; drives symptoms 30–100 nmol/L
AMH Anti-müllerian hormone (ovarian reserve) Elevated in PCOS; indicates higher cyst burden; predictor of fertility outcomes 1.0–3.0 ng/mL (PCOS typically >3.0)
LH:FSH Ratio Luteinizing hormone to follicle-stimulating hormone ratio Elevated ratio (>3:1) = dysfunctional GnRH pulsatility; impairs follicle development (Day 3) LH/FSH <3:1
TSH + Free T4 Thyroid function (stimulating hormone + free thyroxine) Hypothyroidism worsens insulin resistance and PCOS symptoms; must be ruled out TSH: 0.4–2.0 mIU/L; Free T4: 1.0–1.7 ng/dL
Fasting Glucose Baseline blood sugar at rest 40% of PCOS women develop diabetes by age 40; early detection critical <100 mg/dL (fasting)
HbA1c 3-month average glucose control Shows long-term metabolic risk; >5.7% indicates prediabetes; requires intervention
Cortisol (morning) Adrenal stress hormone baseline Chronic stress elevates androgens; elevated morning cortisol worsens metabolic dysfunction 10–20 µg/dL (8am)

Phenotyping

The 4 PCOS Phenotypes

Not all PCOS is created equal. Your phenotype determines your root cause and treatment approach.

Phenotype Key Features Prevalence Metabolic Risk Key Biomarkers Treatment Focus
Type A (Classic) Hyperandrogenism + Ovulatory Dysfunction + Polycystic Ovaries ~40% Highest insulin resistance risk; 70% metabolic syndrome ↑Testosterone, ↑Insulin, ↓SHBG, ↑AMH Insulin sensitization (Metformin/inositol), androgen suppression, lifestyle
Type B (Classic) Hyperandrogenism + Ovulatory Dysfunction (no polycystic ovaries) ~20% Moderate; often adrenal-dominant; 50% metabolic syndrome ↑DHEA-S, ↑LH/FSH, ↑Testosterone, Normal AMH Androgen suppression (OCP or spironolactone), stress reduction, cortisol management
Type C (Ovulatory) Hyperandrogenism + Polycystic Ovaries (regular cycles) ~20% Lower insulin resistance; primarily ovarian androgen excess ↑Testosterone, Normal Insulin, ↑AMH, Normal LH/FSH Androgen suppression (OCP preferred), cosmetic symptom management (hair, acne)
Type D (Non-HA) Ovulatory Dysfunction + Polycystic Ovaries (normal androgens) ~20% High insulin resistance despite normal androgens; metabolic dysfunction masked ↑Insulin, ↑LH/FSH, Normal Testosterone, ↑AMH Intensive insulin management (Metformin, GLP-1), weight loss, metabolic intervention

Why phenotyping matters: Type A requires insulin management; Type B requires androgen suppression and stress control; Type C responds well to birth control; Type D is the most metabolically dangerous and often missed. Your arq. physician identifies your phenotype and personalizes treatment accordingly.

Key Takeaways
Questions

Frequently asked about PCOS

What is PCOS and how is it different from PCOD?
PCOS (Polycystic Ovary Syndrome) and PCOD (Polycystic Ovarian Disease) refer to the same condition — the distinction is largely regional terminology. PCOS is characterized by elevated androgens, irregular cycles, and cyst-bearing ovaries. The key difference from simple ovarian cysts: PCOS involves hormonal dysfunction affecting insulin, testosterone, and LH/FSH ratios. Many women think they have simple ovarian cysts when actually their insulin resistance is the root driver.
Can PCOS be cured permanently?
PCOS cannot be permanently cured, but symptoms can be dramatically improved through targeted treatment. The condition involves genetic and metabolic predisposition, but managing insulin resistance, androgens, and inflammation can restore regular cycles, reduce acne and hair loss, and improve fertility. Most women on arq. protocols see cycle restoration and symptom improvement within 16-20 weeks as their insulin levels normalize.
What blood tests are needed for PCOS diagnosis?
Proper PCOS diagnosis requires measuring: fasting insulin, testosterone (free and total), DHEA-S, LH/FSH ratio, AMH, TSH, free T4, and metabolic markers like fasting glucose and HbA1c. Most Indian clinics check only testosterone or skip insulin entirely — a critical gap since insulin resistance drives 70% of PCOS cases. arq. tests all these markers to identify whether your PCOS is insulin-driven, androgen-driven, or thyroid-influenced.
Is Metformin safe for PCOS?
Metformin is generally safe and effective for insulin-resistant PCOS, often reducing fasting insulin by 20-30%. However, it's prescribed blindly in most Indian clinics without measuring baseline insulin levels. If your PCOS isn't driven by insulin resistance, Metformin may offer little benefit. arq. measures your fasting insulin first — if it's elevated (>12 mIU/L), Metformin is often recommended alongside lifestyle changes. If insulin is normal, alternative approaches work better.
Can PCOS cause weight gain even with diet and exercise?
Yes. Untreated PCOS with insulin resistance can make weight loss extremely difficult because elevated insulin drives fat storage and suppresses appetite regulation. You can diet and exercise perfectly but still struggle because the hormonal environment resists change. When insulin levels normalize through targeted treatment, weight management becomes proportionally easier. This is why bloodwork matters — without addressing insulin, diet alone often fails.
What is the best treatment for PCOS in India?
The best PCOS treatment is personalized and data-driven. Start by measuring insulin, androgens, thyroid function, and metabolic markers via blood tests. If insulin-driven (most common), prioritize insulin-sensitizing supplements (inositol, berberine) and lifestyle changes before or alongside Metformin. If androgen-driven, spironolactone or birth control may help. If thyroid dysfunction is present, treat it. arq. tests all markers, then builds your protocol around your specific imbalances — not a template approach.
Does PCOS affect fertility?
PCOS affects fertility by disrupting ovulation — irregular or absent periods mean irregular or absent ovulation. Insulin resistance and elevated androgens suppress FSH, preventing normal follicle development. However, PCOS-related infertility is highly treatable. Restoring regular cycles through insulin management or hormone therapy often restores fertility. AMH (anti-müllerian hormone) measured by arq. shows your ovarian reserve and helps predict fertility outcomes and treatment response.
How does arq. treat PCOS differently?
arq. doesn't prescribe based on symptoms or assumptions. Your physician reads 100+ biomarkers — insulin, androgens, thyroid, metabolic markers, and more — to identify your root cause. Most women get insulin resistance diagnosed; some discover thyroid dysfunction or adrenal androgen excess. Your protocol (lifestyle, supplements, prescriptions) is built specifically for your markers. You're tracked quarterly, so when your insulin drops or androgens normalize, your treatment adjusts. It's precision medicine, not templates.
