If you’ve been diagnosed with Polycystic Ovary Syndrome but weren’t told what’s driving it, you’re not alone.
PCOS isn’t one condition—it’s a pattern of symptoms with different root causes. That’s why identifying your type (or combination of types) is the first step to making real progress.
This guide walks you through exactly what labs to request—and how to understand what they reveal.
🧠 Step 1: Start With a Full Hormone Panel
These labs help you understand:
- Are you ovulating?
- Are androgens elevated?
- Is brain–ovary signaling off?
Ask for:
- LH (Luteinizing Hormone)
- FSH (Follicle-Stimulating Hormone)
- Estradiol (E2)
- Progesterone (ideally ~7 days after suspected ovulation)
- Total Testosterone
- Free Testosterone
- DHEA-S
- SHBG (Sex Hormone Binding Globulin)
What this tells you:
- High LH:FSH ratio → disrupted brain signaling
- High testosterone → androgen excess
- High DHEA-S → adrenal involvement
- Low progesterone → lack of ovulation
🍬 Step 2: Test for Insulin Resistance (Most Important)
Even if your glucose is normal, insulin can still be elevated.
Ask for:
- Fasting insulin
- Fasting glucose
- HbA1c
- Oral Glucose Tolerance Test (OGTT) (ideally with insulin measured at multiple time points)
What this tells you:
- Elevated insulin → Insulin-Resistant PCOS
- Normal glucose + high insulin → early insulin resistance
💡 Many doctors skip insulin—don’t let this be overlooked
🔥 Step 3: Check for Inflammation
Inflammation is often silent but powerful.
Ask for:
- hs-CRP (high-sensitivity C-reactive protein)
- Fasting triglycerides
- Vitamin D
What this tells you:
- Elevated CRP → systemic inflammation
- High triglycerides → metabolic + inflammatory stress
- Low vitamin D → increased inflammatory risk
👉 Points toward Inflammatory PCOS
😴 Step 4: Evaluate Adrenal Function
This helps identify stress-driven hormone imbalances.
Ask for:
- DHEA-S (already included, but critical here)
- Cortisol (AM blood test)
- (Optional) 4-point salivary cortisol test
What this tells you:
- High DHEA-S → adrenal androgen excess
- Dysregulated cortisol → stress-driven hormone disruption
👉 Points toward Adrenal PCOS
💊 Step 5: Don’t Skip Thyroid Testing
Thyroid issues can mimic or worsen PCOS symptoms.
Ask for:
- TSH
- Free T3
- Free T4
- TPO antibodies
- Thyroglobulin antibodies (TgAb)
What this tells you:
- Thyroid dysfunction may be contributing to:
- Fatigue
- Weight changes
- Irregular cycles
🧬 Step 6: Additional Helpful Labs
These aren’t always required—but they give valuable context:
- Prolactin → elevated levels can stop ovulation
- Liver enzymes (AST/ALT) → assess metabolic health
- Lipid panel → cholesterol + triglycerides
- Ferritin (iron stores) → low levels can affect energy + hormones
🔍 How to Connect Your Results to Your “Type”
Once you have your labs, look for patterns:
🍬 Insulin-Resistant PCOS
- High fasting insulin
- Abnormal OGTT
- Low SHBG
- Elevated testosterone
🔥 Inflammatory PCOS
- Elevated hs-CRP
- High triglycerides
- Low vitamin D
- Symptoms of chronic inflammation
😴 Adrenal PCOS
- Elevated DHEA-S
- Normal insulin/glucose
- Cortisol irregularities
💊 Post-Pill PCOS
- Recent discontinuation of birth control
- Temporary hormone imbalance
- Labs may look mixed or mild
⚠️ Important: You May Have More Than One
Most women don’t fall into just one category.
👉 You might have:
- Insulin resistance + inflammation
- Adrenal involvement on top of metabolic issues
That’s why interpreting patterns—not just individual numbers—is key
❓ What to Ask Your Doctor
Getting labs is step one—understanding them is step two.
Ask:
- “Am I ovulating based on these results?”
- “Do I show signs of insulin resistance—even if glucose is normal?”
- “Are my androgen levels elevated, and where are they coming from?”
- “Do any markers suggest inflammation?”
- “Is stress or adrenal function playing a role?”
- “What do YOU think is driving my PCOS?”
💡 The Real Goal of Testing
This isn’t about collecting numbers.
It’s about answering one question:
What is disrupting my body’s ability to ovulate and regulate hormones?
🔄 Why This Changes Everything
When you identify your root driver:
- You stop guessing
- You stop wasting time on the wrong strategies
- You start supporting your body in a targeted way
👉 That’s when real progress happens
💛 Final Thought
A PCOS diagnosis is just the beginning.
The real work—and the real progress—starts when you ask:
👉 “What’s causing this in my body?”
Because once you know that…
You can finally start treating the root—not just the symptoms
