PCOS Tests and Your Doctor's Appointment: What to Bring and Ask
How to prepare for a PCOS appointment: the blood tests and scans doctors use, what to track beforehand, questions to ask, and how to make sure you're heard.
Many people with PCOS say they felt rushed or dismissed at their first appointment. Preparation changes that. When you bring clear data and specific questions, it’s easier for your clinician to reach a diagnosis and agree a plan with you.
Before the appointment: what to track
Start at least one to three months ahead if you can.
- Period start dates. These give your real cycle lengths, the single most useful piece of information
- Bleeding details. How many days, and how heavy
- Symptoms. Acne, excess hair, hair thinning, fatigue, cravings and mood, and how often they appear
- Weight, if it’s relevant to you, measured weekly rather than daily
- Medications and supplements, including doses and when you started them
- Family history. PCOS, type 2 diabetes, high cholesterol or heart disease in close relatives

Tests your doctor may use
PCOS is diagnosed with the Rotterdam criteria, two of three features after other causes are ruled out. Read more in What is PCOS?. Tests often include:
| Test | Why |
|---|---|
| Total testosterone and SHBG (free androgen index) | To check for higher androgens |
| TSH (thyroid) | To rule out thyroid problems |
| Prolactin | To rule out a prolactin-related cause |
| 17-hydroxyprogesterone | To rule out non-classic congenital adrenal hyperplasia |
| Pregnancy test | If periods are missing |
| Pelvic ultrasound or AMH | To look for polycystic ovaries (adults only, and not always needed) |
Because PCOS affects long-term health, your doctor should also check:
- Blood sugar, ideally with an oral glucose tolerance test, or HbA1c or fasting glucose
- Cholesterol and other lipids
- Blood pressure and, often, weight and waist measurements
- Mood, with questions about anxiety, depression and eating
Questions worth asking
About diagnosis:
- Do I meet the criteria for PCOS? Which features do I have?
- Which other conditions have we ruled out?
About treatment:
- What are my options for my main concern (cycles, skin and hair, weight, fertility, mood)?
- How will we know if a treatment is working, and when should we review it?
- My periods are very infrequent. How do we protect the uterine lining?
About long-term health:
- How often should I have blood sugar, cholesterol and blood pressure checks?
- If I want to get pregnant now or later, what should I know?
How to make sure you’re heard
- Lead with your main concern in one sentence: “My cycles range from 33 to 52 days and I want to understand why.”
- Bring numbers, not impressions. “Acne on 35 of the last 90 days” lands differently from “my skin is bad.”
- Ask for referrals to an endocrinologist, gynaecologist, dermatologist or dietitian if needed.
- It’s fine to get a second opinion if your concerns aren’t taken seriously.
After the appointment
Write down what was agreed: the diagnosis, tests ordered, treatment and when to review it. Then keep tracking, so the next visit starts with clear before-and-after data.

Frequently asked questions
What blood tests are done for PCOS?
Common tests include testosterone and SHBG to check androgens, plus tests to rule out other causes such as thyroid function (TSH), prolactin and 17-hydroxyprogesterone. AMH may be used instead of an ultrasound in adults. Blood sugar and cholesterol are checked for long-term health.
Can a blood test alone diagnose PCOS?
No. PCOS is diagnosed from a combination of cycle history, signs of higher androgens and, sometimes, ultrasound or AMH, after other conditions have been ruled out.
Should I stop birth control before PCOS testing?
Hormonal birth control can affect hormone test results. Don't stop it on your own. Ask your doctor whether a break is needed before testing and how to stay protected from pregnancy in the meantime.
