PCOS — polycystic ovary syndrome — is one of the most common hormonal conditions affecting women of reproductive age, yet two people with the same diagnosis can have very different hormone patterns underneath it. That's where PCOS hormone testing earns its keep. This guide explains the androgen excess at the heart of PCOS, the difference between ovarian and adrenal drivers, the cortisol connection, and exactly what the DUTCH™ test adds — while being clear about what it can and can't tell you.
Key takeaways
- PCOS is an androgen-excess condition. Elevated testosterone, DHT, or DHEA-S drives the classic signs — acne, unwanted hair, and irregular cycles.
- Testing is not a diagnosis. PCOS is diagnosed clinically by a physician; the DUTCH™ test adds detail to bring to that conversation.
- Ovarian vs. adrenal source matters. The DUTCH™ test separates testosterone and androgens in women from adrenal DHEA-S, hinting at where the excess originates.
- Cortisol belongs in the picture. An adrenal-driven pattern links stress and androgens, which the DUTCH™ cortisol curve helps reveal.
- Progesterone often runs low. Irregular ovulation can leave estrogen relatively unopposed — see estrogen dominance.
PCOS and androgen excess
At its core, PCOS is a condition of androgen excess combined with disrupted ovulation. Androgens — testosterone, DHT, and DHEA — are present in every woman's body in small amounts, but when they run high, they produce the signs most associated with PCOS: acne along the jaw and chin, unwanted facial or body hair (hirsutism), scalp hair thinning, and irregular or absent periods. Because ovulation is disrupted, cycles become unpredictable, and the resulting shortfall in progesterone can leave estrogen relatively unopposed.
These are, in effect, a specific cluster within the broader family of hormone imbalance symptoms. What makes PCOS distinctive is the androgen signature — and that signature is exactly what a comprehensive hormone test can characterize in more detail than a single testosterone value.
How PCOS is diagnosed
It's important to be precise here: PCOS is a clinical diagnosis, made by a physician. The widely used Rotterdam criteria require at least two of three features — irregular or absent ovulation, clinical or biochemical signs of high androgens, and polycystic ovaries on ultrasound — after other conditions have been ruled out. No single at-home test can make that call.
So where does hormone testing fit? It adds biochemical detail: how high the androgens are, which androgens are elevated, how they're being metabolized, and what the cortisol picture looks like. That detail is valuable context to bring to the provider who is making or managing the diagnosis — a complement to the clinical workup, not a replacement for it.
A wellness tool, not a verdict
The DUTCH™ test can show that androgens are elevated and suggest where they're coming from — but it cannot, by itself, tell you that you have PCOS. Think of it as a detailed map you hand to your physician, who combines it with your history, exam, and other tests to reach a diagnosis and plan.
Testosterone- vs. DHEA-driven patterns
One of the most useful distinctions in PCOS is where the excess androgens originate, because it points toward different contributing factors:
- Ovarian, testosterone-driven. The ovaries are the main source; testosterone and its potent metabolite DHT are elevated. This is the most common pattern and often connects to insulin dynamics.
- Adrenal, DHEA-driven. The adrenal glands contribute more of the load, and DHEA-S runs high. This pattern is sometimes called "adrenal PCOS" and ties into the stress system.
The DUTCH™ test reports ovarian androgens and adrenal DHEA-S separately, along with their downstream metabolites — including the 5-alpha reductase pathway that produces DHT and drives skin and hair symptoms. Seeing that breakdown helps a practitioner understand whether testosterone, DHT, or DHEA is the more prominent player, which pure serum testosterone alone can obscure.
The cortisol and adrenal connection
Here's a link that's easy to miss: the adrenal glands make both cortisol and DHEA. That shared origin means the stress system and the androgen system are wired together. In an adrenal-driven pattern, chronic stress and HPA-axis dysfunction can push adrenal androgen output up alongside a disrupted cortisol rhythm.
Because the DUTCH™ test maps the daily cortisol curve in the same collection that measures androgens, it lets a practitioner view stress and androgens together. That combined view is genuinely hard to assemble from separate blood tests taken on different days, and it can change how the pattern is interpreted.
What the DUTCH™ test adds
For someone exploring a PCOS-type pattern, the DUTCH™ Complete ($499) is the natural fit: it reports sex hormones and their metabolites, ovarian and adrenal androgens, the androgen metabolite pathways, and the cortisol curve in a single at-home collection. New to the format? See what the DUTCH™ test is for how dried-urine testing works.
Because cycles in PCOS are often irregular, timing a single sample can be tricky. In some cases a practitioner may prefer Cycle Mapping, which tracks estrogen and progesterone across many days to characterize whether and when ovulation occurs. Either way, results are typically ready about 2–3 weeks after the lab receives your samples.

Because PCOS is a clinical diagnosis with meaningful long-term health implications, the results of any hormone test should be reviewed with a qualified provider who can place them in the context of your symptoms, exam, and other labs such as insulin and glucose. The DUTCH™ report is designed to make that conversation richer — showing not just whether androgens are high, but which ones and from where.
If you've already been diagnosed, the same detail can help track how a pattern shifts over time as you and your provider adjust your approach. Testing gives you a baseline and a way to see change, rather than relying on symptoms alone.
Frequently asked questions
No. PCOS is a clinical diagnosis made by a physician using the Rotterdam criteria, which combine irregular ovulation, signs of high androgens, and ultrasound findings, after ruling out other conditions. The DUTCH™ test is a wellness tool that adds detail about androgen levels, their metabolites, and the cortisol picture — useful information to bring to your provider, not a substitute for medical diagnosis.
PCOS is characterized by androgen excess — most often testosterone and its potent metabolite DHT, and sometimes DHEA-S from the adrenal glands. Irregular or absent ovulation also lowers progesterone, which can leave estrogen relatively unopposed. Insulin and cortisol frequently play a role too, which is why a fuller hormone picture is helpful.
In testosterone-driven patterns, the excess androgens come mainly from the ovaries, and testosterone and DHT are elevated. In DHEA-driven patterns, the adrenal glands are the larger source, and DHEA-S runs high. The DUTCH™ test reports both ovarian and adrenal androgens plus their metabolites, which can help a practitioner see which source is more prominent.
The adrenal glands produce both cortisol and DHEA, so chronic stress and HPA-axis dysfunction can contribute to an adrenal-driven androgen pattern sometimes called adrenal PCOS. Because the DUTCH™ test maps the daily cortisol curve alongside androgens, it lets a practitioner see the stress and androgen picture together rather than in isolation.
