PCOS Blood Test in Dubai: Which Hormones and What They Mean

Polycystic ovary syndrome affects around 12% of women of reproductive age, and a large share of them are never diagnosed.⁶ The usual route to that diagnosis begins with a blood test, which is where most of the confusion also begins. People arrive at a lab expecting a single number that will say yes or no, and that number does not exist.

This guide explains what a PCOS blood panel actually measures, what each hormone is doing there, when in your cycle to have blood drawn, and what the results can and cannot settle.

Important: This article is for general education and does not replace medical advice. Laboratory results should always be interpreted by a licensed physician in the context of your individual history and examination.

Start here: no blood test diagnoses PCOS

This is the single most useful thing to understand before you book anything.

PCOS is diagnosed against international criteria, most recently set out in the 2023 International Evidence-Based Guideline, which built on the 2003 Rotterdam criteria. In adults, a diagnosis requires at least two of the following three:¹

1. Clinical or biochemical hyperandrogenism. Either visible signs of excess androgens, such as persistent acne, unwanted hair growth or scalp thinning, or raised androgens on a blood test.
2. Ovulatory dysfunction. Irregular cycles, infrequent periods or absent periods.
3. Polycystic ovarian morphology. Traditionally assessed on ultrasound, and since 2023, anti-Müllerian hormone (AMH) is accepted as an alternative in adults.

Notice what follows from this. If you already have irregular cycles and clear clinical signs of androgen excess, which describes roughly 70% of cases, you meet two criteria and the guideline says neither an ultrasound nor AMH testing is required for diagnosis.³ Blood work still matters, but its main job shifts.

So what is the blood test for? Two things:

• To provide biochemical evidence of androgen excess when the clinical picture alone is not clear.
• To rule out the conditions that look like PCOS but are not. Thyroid disease, high prolactin and several other disorders produce irregular cycles and overlapping symptoms. PCOS is a diagnosis of exclusion as much as inclusion, and a good panel is built to exclude.

A useful way to read your report: the androgen markers are looking for something, and the thyroid and prolactin markers are looking to rule things out.

What is in the PCOS panel

Our PCOS profile is 16 markers from a single blood draw, at AED 499 with free home collection and results in 72 hours. The markers group into four jobs.

Marker by marker: what each result means

Total testosterone

The headline androgen test. Women produce testosterone normally, in small amounts. In PCOS it is often raised, and that excess drives the acne, the hair growth and part of the cycle disruption.

Read this one with care. Most testosterone in your blood is bound to a carrier protein called sex hormone binding globulin (SHBG) and is biologically inactive. Only the unbound fraction does anything. In PCOS, insulin tends to suppress SHBG, which means more of your total testosterone is free and active. The practical consequence is that total testosterone can read as normal while your free, active testosterone is genuinely elevated. This is a well-recognised limitation, and it is why the international guideline points toward calculated free testosterone or the free androgen index rather than total testosterone alone.⁴ More on how to close that gap below.

A markedly high testosterone, well above the usual PCOS range, is a different situation and warrants prompt specialist review rather than reassurance.

LH and FSH

Two pituitary hormones that drive the ovarian cycle. In PCOS, LH is often disproportionately high relative to FSH.

The LH to FSH ratio is not a diagnostic test. You will find a great deal written online about a ratio above 2:1 or 3:1 confirming PCOS. It does not. The ratio is raised in many women with PCOS and normal in many others, and it is raised in some women without PCOS. It appears in no current diagnostic criteria.¹ Treat it as a supporting observation your doctor may find interesting, not as a verdict.

FSH has a second, more decisive use: a clearly elevated FSH points away from PCOS and toward reduced ovarian reserve or primary ovarian insufficiency, which is a different diagnosis with different management.

Estradiol

The main oestrogen. On its own it says little about PCOS. Its value here is contextual: it helps your doctor interpret the FSH and LH results and work out roughly where in a cycle the sample was taken, which matters when cycles are irregular and dates are uncertain.

Progesterone

This one is about ovulation, and it is entirely dependent on timing. Progesterone rises after ovulation and stays up for around a week. A blood sample taken roughly seven days before your period is due should show a clear rise if you ovulated in that cycle. A low result at that point suggests you did not.

Drawn at a random point, or drawn when cycles are irregular enough that you cannot predict the next period, progesterone is difficult to interpret. Tell whoever reviews your report where you were in your cycle, or that you do not know.

Prolactin

An exclusion test, and an important one. Raised prolactin stops periods and can closely mimic PCOS. The causes range from benign pituitary adenomas to several common medications, including some antidepressants and anti-nausea drugs. It is treatable, and treating it often restores cycles, so it needs ruling out before anyone settles on PCOS.

Prolactin rises transiently with stress, recent exercise, breast stimulation and even a difficult blood draw, so a mildly raised single result is usually repeated before it means anything.

TSH, free T3 and free T4

The other main exclusion. An underactive or overactive thyroid disrupts periods, causes fatigue and weight change, and is common in women of reproductive age. TSH is the most sensitive single indicator; free T3 and free T4 show what the gland is actually producing.

Thyroid disease and PCOS are not mutually exclusive, and autoimmune thyroid disease is more common in women with PCOS, so a thyroid result that is off does not automatically mean PCOS is off the table.

HbA1c and fasting glucose

PCOS carries a substantially increased risk of insulin resistance and type 2 diabetes, independent of body weight. This is not an optional add-on to the picture; it is central to what the condition does over a lifetime.

One caveat worth knowing. The 2023 international guideline recommends the 75g oral glucose tolerance test as the most accurate assessment of glucose status in PCOS, regardless of BMI, with fasting glucose and then HbA1c described as less accurate but acceptable choices.⁶ This is not a small difference: in a meta-analysis comparing them against the OGTT in women with PCOS, an HbA1c threshold of 6.5% detected only about half of the diabetes cases the OGTT found.⁵ HbA1c and fasting glucose are a reasonable starting point and a good tracking tool, but a normal result on either does not exclude a glucose problem as reliably as it would in the general population.

The lipid panel

Total cholesterol, HDL, LDL, VLDL and triglycerides. Women with PCOS have a higher cardiovascular risk profile, and the guideline recommends lipid monitoring.⁶ The pattern most often seen is raised triglycerides with low HDL, which tends to track with insulin resistance rather than with diet alone.

Timing: when in your cycle to have blood taken

This is where good tests get wasted, and it costs nothing to get right.

If your cycles are reasonably regular:

• FSH, LH and estradiol: early in the cycle, generally days 2 to 5, counting day 1 as the first day of proper bleeding.
• Progesterone: about 7 days before your next period is due, which is day 21 of a 28-day cycle but later in a longer one.
• Testosterone: in the morning. Androgens follow a daily rhythm and are highest early.

If your cycles are irregular or absent: this is the most common situation in PCOS, and it is not a problem. Have the blood drawn whenever is practical, and tell the reviewing physician that your cycles are irregular and roughly when your last period was. That context is what lets the result be read correctly. Do not postpone testing for months waiting for a period that may not arrive.

Fasting: the panel includes fasting glucose and a lipid profile, so plan on 10 to 12 hours without food. Plain water is fine and encouraged.

Rule out pregnancy first. A missed period has a common explanation that no hormone panel is designed to look for. If there is any chance, take a pregnancy test before booking a workup.

If you take the contraceptive pill, read this before booking

This deserves its own section because it invalidates a large part of the panel and very few people are told.

The combined oral contraceptive pill raises SHBG and suppresses the ovarian production of androgens. The international guideline is explicit that biochemical hyperandrogenism cannot be reliably assessed on the pill, and that if the assessment is essential, the pill needs to be stopped for a minimum of three months, with contraception managed another way in the meantime.¹

The same logic applies to the cycle hormones. On the pill, your FSH, LH, estradiol and progesterone reflect the medication, not your own ovaries.

What this means in practice:

• Do not stop taking the pill to get a blood test. Speak to your doctor first. That is a medical decision with contraceptive consequences, and it is theirs and yours to make together.
• If you are on the pill and want useful bloods now, the metabolic and thyroid parts of the panel remain fully valid. The androgen and cycle hormones do not.
• If your doctor is working toward a formal PCOS diagnosis, they will advise on the washout period.

Mention any hormonal contraception when you book, so this is factored into your report rather than discovered afterwards.

What this panel does not cover, and when to add something

An honest account of the limits, because a panel you understand is worth more than a panel you assume.

SHBG, or free testosterone

The gap discussed above. The panel measures total testosterone only, and in PCOS that can read normal while the biologically active fraction is high.

Adding SHBG (AED 70) lets the free androgen index be calculated from your total testosterone, which is what the guideline evidence supports. Alternatively, free testosterone (AED 90) measures the active fraction directly.⁴ If your doctor is building a formal diagnosis and your clinical signs of androgen excess are not obvious, this is the single most useful addition to make.

DHEA-S

Around a fifth to a third of women with PCOS have androgen excess coming from the adrenal glands rather than the ovaries, which total testosterone can miss. The guideline suggests considering DHEA-S when testosterone or free testosterone is not elevated, while noting it is less specific.¹ DHEA-S (AED 75) is inexpensive and worth discussing if your androgen results come back normal but your symptoms have not.

A 75g oral glucose tolerance test

For the reasons set out above, this is the guideline's preferred way to assess glucose status in PCOS. The 75g GTT (AED 50) involves a fasting draw, a glucose drink, and further draws at one and two hours, so it takes a morning rather than ten minutes. If insulin resistance is a live question for you, it answers it far better than HbA1c alone.

Fasting insulin and HOMA-IR

Frequently requested, so worth being straight about: insulin testing is not part of the diagnostic criteria for PCOS, and the international guideline does not recommend it for diagnosis.¹ Some clinicians use fasting insulin or HOMA-IR to track change over time, and it is available here if your doctor has asked for it, but a normal or abnormal insulin does not confirm or exclude anything on its own.

AMH and 17-hydroxyprogesterone

Two tests that belong in a complete PCOS workup and sit outside the PCOS profile.

AMH can substitute for ultrasound in defining polycystic ovarian morphology in adults, though note it is not recommended in adolescents or within about eight years of a first period, where it lacks specificity.³ AMH (AED 240) is not one of the 16 markers in the AED 499 panel, so book it alongside if your doctor wants it: one serum sample, results in 2 to 3 days, and because AMH is stable across the cycle it can be drawn on the same visit whatever day you are on.

17-hydroxyprogesterone is used to exclude non-classic congenital adrenal hyperplasia, a condition that can present almost identically to PCOS.² It is not on our menu; if your doctor wants it, they will arrange it. We would rather say so than pretend the panel covers ground it does not.

If you need a combination the standard panels do not carry, you can build a custom panel marker by marker.

Your results are back. What now?

Take them to a doctor. Every report here is physician-reviewed and annotated in plain language, and a clinician will talk you through what each marker showed. But a PCOS diagnosis also draws on your cycle history, your symptoms, a physical assessment and sometimes a pelvic ultrasound. Blood results are one input into that, not a substitute for it.

Normal results do not mean nothing is wrong. If all 16 markers come back within range and your periods are still absent and your symptoms are still there, that is meaningful information, not a dead end. It has ruled out thyroid disease and high prolactin, and it points your doctor toward the next question rather than the same one.

Abnormal results do not confirm PCOS either. A single raised testosterone in isolation is a finding to interpret, not a diagnosis to accept.

What a PCOS diagnosis means beyond the hormones

Two things the 2023 guideline emphasised that rarely make it into lab marketing, and both are worth saying.

PCOS is a long-term metabolic and cardiovascular condition, not only a fertility one. The increased risk of type 2 diabetes and the cardiovascular risk profile persist across life and deserve regular monitoring, whatever your current plans around children. This is the main argument for repeating the metabolic markers periodically rather than testing once and filing the report.

The psychological burden is high and routinely overlooked. Rates of depression and anxiety are markedly increased in women with PCOS, with odds ratios around 2.6 and 2.7 respectively, and the guideline recommends routine screening for both.⁶ If the diagnosis or the symptoms are affecting how you feel, that is a recognised part of the condition and a reasonable thing to raise with your doctor, not a side issue.

On lifestyle: healthy lifestyle changes are part of managing PCOS, and the guideline is equally clear that this should be approached with awareness of weight stigma, focused on health and wellbeing rather than on weight alone.¹ What suits you is a conversation with your doctor or a dietitian who knows your history. A blood panel is not the place for a diet plan, and we are not going to give you one.
