PMOS (PCOS) blood test · Plymouth
A PMOS blood test, with the full picture.
PMOS, still widely known as PCOS, is one of the most common hormone conditions. One blood test checks the hormonal, metabolic and Thyroid markers used in assessment. No GP referral needed.
About PMOS
Often missed for years.
Symptoms vary a lot from one person to the next: irregular periods, weight that is hard to shift, acne, extra hair growth, hair thinning or trouble getting pregnant.
PMOS is diagnosed on clinical grounds. Blood tests are one part of that. They show raised androgens, rule out other causes such as Thyroid problems or raised Prolactin, and check for insulin resistance.

What is measured
What the PMOS Screen checks.
| Test | What it covers | Why it matters |
|---|---|---|
| Testosterone, SHBG and FAI | Androgens and the protein that carries them | Raised levels are found in most people with PMOS. |
| LH and FSH | Pituitary hormones | A high LH to FSH ratio is a classic feature, though not everyone has it. |
| DHEA-S | An androgen made by the adrenal glands | Helps work out where extra androgens come from. |
| Prolactin and Thyroid | Prolactin, TSH, Free T4 and Free T3 | Problems here can look very like PMOS, so they are ruled out. |
| Insulin, Glucose and HbA1c | Blood sugar control | Insulin resistance is common with PMOS and matters for long-term health. |
| Cholesterol, liver, kidney and blood count | General health | A baseline for heart health and overall wellbeing. |

Your results
What your results mean.
Your results come with a plain English summary from a clinician, explaining what they show and what they do not.
A diagnosis also depends on your symptoms, and sometimes a pelvic ultrasound. We explain the next steps, which may include a follow-up appointment or a referral.
Blood tests give information. They do not diagnose a condition on their own. We explain your results in the context of your symptoms, medicines and history.

About the test
What is the difference between PMOS and PCOS?
They are the same condition. PMOS is the newer name, chosen because many people do not have cysts on their ovaries.
Does a normal result rule out PMOS?
Not always. The diagnosis also depends on your symptoms and sometimes an ultrasound. We explain what your results mean for you.
Can I test while on the pill?
You can, but the pill lowers androgens, which can hide the signs. Tell us if you take it when you book.
