Lab Tests for PCOS
Polycystic ovary syndrome (PCOS) is a hormonal disorder affecting up to 12% of women of reproductive age. Lab testing is crucial for diagnosing PCOS and identifying which hormonal imbalances are driving your symptoms, whether elevated androgens, insulin resistance, or both. A thorough PCOS lab workup includes hormone levels, metabolic markers, and thyroid function to rule out other conditions that mimic PCOS symptoms. JustLabs lets you order a complete PCOS panel online without a doctor visit at transparent self-pay prices.
Recommended Tests
Understanding Your Results
| Test | Normal Range | Low Means | High Means |
|---|---|---|---|
| Testosterone | Female: 15–70 ng/dL | May rule out androgen-driven PCOS | Elevated androgens — supports PCOS diagnosis |
| DHEA-S | Female: 35–430 mcg/dL | Adrenal androgen production low | Adrenal contribution to androgen excess |
| FSH/LH Ratio | LH:FSH ~1:1 | Normal pituitary signaling | Elevated LH:FSH ratio (>2:1) suggests PCOS |
| Fasting Insulin | <25 mIU/L | Normal insulin sensitivity | Insulin resistance — common in PCOS |
| HbA1c | <5.7% | Normal blood sugar control | Prediabetes or diabetes risk from PCOS |
