PCOS Hormonal Panel: What to Expect

PCOS (Polycystic Ovary Syndrome) affects 6–12% of women of reproductive age in the U.S., yet up to 70% of cases remain undiagnosed. Hormonal testing is a key step in diagnosing PCOS and ruling out other conditions with similar symptoms like thyroid disorders or Cushing syndrome. Here's what you need to know:

• Why Testing Matters: Identifies hormone imbalances like high androgens or an altered LH/FSH ratio, which are common in PCOS.
• When to Test: If you have irregular periods, acne, excess facial hair, or sudden weight gain, consult your doctor. Testing is best done between days 3–7 of your menstrual cycle.
• Hormones Tested: Includes LH, FSH, testosterone, SHBG, AMH, DHEAS, TSH, prolactin, and more. Elevated testosterone and AMH, low SHBG, and an LH:FSH ratio above 2:1 often indicate PCOS.
• How to Prepare: Fast 8–12 hours beforehand, avoid biotin supplements, and schedule tests in the morning for accuracy.
• Results: Elevated testosterone (>70 ng/dL), low SHBG (<30 nmol/L), or high AMH (>4 ng/mL) can point to PCOS. Your doctor will interpret these alongside symptoms for a diagnosis.

Telehealth services like Oana Health provide convenient at-home testing, result interpretation, and treatment options tailored to PCOS symptoms. Early diagnosis and proper care can improve symptoms and lower risks of long-term complications like diabetes or heart disease.

Hormones Tested in a PCOS Panel

Main Hormones Measured

A PCOS hormonal panel typically includes tests for 11 key hormones that provide insight into reproductive and metabolic health: LH, FSH, total and free testosterone, SHBG, DHEAS, AMH, estradiol, TSH, prolactin, androstenedione, and 17‑hydroxyprogesterone. Each of these hormones plays a role in confirming a PCOS diagnosis or ruling out other conditions. For instance, testosterone levels are used to identify androgen excess, while TSH screening ensures that thyroid issues aren’t causing similar symptoms.

Some labs may also include a cortisol test to rule out Cushing syndrome. The specific tests ordered often depend on your symptoms and your doctor’s clinical judgment. Below, we’ll break down how each hormone contributes to understanding PCOS.

How Each Hormone Connects to PCOS

LH and FSH are critical in regulating the menstrual cycle, and an LH:FSH ratio higher than 2:1 often points to disrupted ovulation, a common feature of PCOS. Elevated levels of total or free testosterone - present in around 60–80% of women with PCOS - are a hallmark of the condition and are linked to symptoms such as persistent acne, unwanted facial hair, and irregular menstrual cycles.

SHBG, a protein that binds hormones, often drops in women with PCOS. Lower SHBG means more free testosterone circulates in the bloodstream, intensifying its effects. Additionally, women with PCOS typically have AMH levels two to three times higher than average due to an increased number of small ovarian follicles.

Other hormones are also measured to refine the diagnosis. TSH and prolactin help rule out thyroid dysfunction and hyperprolactinemia, respectively. Testing for 17‑hydroxyprogesterone distinguishes PCOS from non‑classic congenital adrenal hyperplasia. For example, elevated testosterone paired with normal 17‑hydroxyprogesterone levels supports a PCOS diagnosis, while significantly high 17‑hydroxyprogesterone suggests non‑classic congenital adrenal hyperplasia.

Testing Standards in the US

To accurately assess hyperandrogenism and ovulatory function, US guidelines recommend measuring core hormones. Blood samples are typically collected in the morning while fasting, ideally between days 3 and 7 of your menstrual cycle, when hormone levels are most stable. If your periods are irregular or absent, testing can be done regardless of timing.

Several factors can influence test results. Hormonal contraceptives may lower testosterone, LH, FSH, and AMH levels while raising SHBG. Taking biotin supplements within eight hours of testing can interfere with certain assays, and recent illness or high stress levels might also affect hormone levels. These considerations help ensure that test results align with your clinical symptoms for an accurate diagnosis.

For convenient PCOS testing, telehealth platforms like Oana Health offer lab coordination, result interpretation, and prescription treatments tailored to PCOS symptoms. With medications delivered straight to your home, this approach makes comprehensive PCOS care more accessible across the United States.

Reading Your Test Results

Test Results That Point to PCOS

When it comes to diagnosing PCOS, certain hormone patterns stand out. One of the most telling signs is elevated testosterone levels. Women with PCOS often have total testosterone levels above 70 ng/dL, while the normal range is between 15–70 ng/dL. Similarly, free testosterone levels - normally between 0.3–3.5 pg/mL - tend to exceed this range in PCOS cases.

Another important clue is low SHBG (sex hormone-binding globulin) levels. If SHBG drops below 30 nmol/L, more testosterone circulates freely in the bloodstream. This can worsen symptoms like acne, excess facial hair, and scalp hair loss. This link between low SHBG and elevated free testosterone is a key factor in understanding why some women experience more pronounced symptoms than others.

The LH (luteinizing hormone) to FSH (follicle-stimulating hormone) ratio is another marker. In PCOS, this ratio is often greater than 2:1, with LH levels exceeding 10 IU/L during the follicular phase. This imbalance can disrupt ovulation, leading to irregular menstrual cycles. However, it’s worth noting that not all women with PCOS have an abnormal LH:FSH ratio, which is why doctors evaluate multiple markers rather than relying on just one.

AMH (anti-Müllerian hormone) levels are also frequently elevated in PCOS, often measuring above 4 ng/mL, compared to the normal range of 1–4 ng/mL. This reflects an increased number of small ovarian follicles, a hallmark of PCOS that can also be observed on an ultrasound.

To summarize these findings, the table below highlights the differences between normal and PCOS-related hormone levels.

Normal vs PCOS Hormone Levels

Comparing your results to standard ranges can provide clarity on whether PCOS might be impacting your hormones. The table below outlines key differences in hormone levels.

Keep in mind that lab reference ranges may vary slightly, so your doctor will interpret your results based on the specific ranges provided by the testing facility. What matters most is identifying patterns rather than focusing on single abnormal values.

For instance, consider a 28-year-old woman with irregular periods and acne. Her test results might show total testosterone at 110 ng/dL, LH at 15 IU/L, FSH at 6 IU/L (resulting in an LH:FSH ratio of 2.5:1), and SHBG at 20 nmol/L. These findings - elevated testosterone, high LH, low SHBG, and an LH:FSH ratio above 2:1 - alongside her symptoms, strongly suggest PCOS.

Doctors also account for factors like medications and supplements that can skew hormone levels. For example, hormonal contraceptives and biotin may affect test accuracy. Timing is another consideration; blood tests are most reliable when done on days 3–7 of the menstrual cycle. If cycles are irregular or absent, testing can proceed at any time. Your provider will take all these variables into account when diagnosing PCOS and planning treatment.

Understanding your results is a crucial step toward managing PCOS effectively. For personalized care and treatment options, telehealth platforms like Oana Health provide expert support, including prescription-based solutions delivered straight to your home. This approach makes managing PCOS more accessible and tailored to your unique hormone profile.

The Testing Process Step by Step

How to Prepare for Your Test

To get the most accurate results, plan to fast for 8–12 hours before your blood draw and, if possible, schedule your test between days 3 and 7 of your menstrual cycle. For those with irregular cycles, testing on any weekday works, and your healthcare provider will interpret the results accordingly.

Make sure to list all medications and supplements you’re currently taking. This step is essential because some substances can interfere with hormone levels. Hormonal contraception and biotin supplements, in particular, can affect results and should be disclosed to your provider. Some experts recommend stopping biotin at least 8 hours before the test to avoid inaccuracies.

It’s also best to schedule your test in the morning, as hormone levels tend to be more stable earlier in the day. Choose an early appointment time and wear a top with sleeves that can easily be rolled up to simplify the blood draw.

Once you’ve prepared, here’s what to expect during the actual blood draw.

What Happens During Blood Draw

The blood collection process is quick and straightforward. A trained phlebotomist will clean your arm, insert a small needle into a vein (usually in the inner elbow), and collect several vials of blood. The entire procedure typically takes less than 10 minutes, with the actual blood collection lasting just a few minutes.

You might feel a brief pinch, but serious discomfort is rare. Multiple vials are usually collected to test for a range of hormones, including FSH, LH, total and free testosterone, SHBG, DHEA-S, estradiol, and sometimes AMH.

Once the blood draw is complete, a bandage will be applied, and you can resume your normal activities immediately. If you feel a little lightheaded afterward - especially if you’ve been fasting - have a snack and drink some water to recover.

For added convenience, services like Oana Health offer in-home blood draws. A trained professional can visit your home to perform the same procedure, providing privacy and flexibility.

After your blood is drawn, the next step is reviewing your results.

Getting Your Results

You can expect your results within 2–7 business days, depending on the complexity of the tests and the lab’s processing time. Results are often shared through secure online portals, over the phone, or during a follow-up consultation.

Your healthcare provider will go over the results, explaining what your hormone levels indicate about PCOS and outlining the next steps. This might include additional testing, such as a pelvic ultrasound, or developing a treatment plan tailored to your hormonal profile.

Telehealth services have made this process more convenient. Providers like Oana Health offer virtual consultations to review results and discuss personalized treatment options. This eliminates the need for extra in-person visits and can help you move from testing to treatment more quickly.

If you’re unsure about any part of your results, don’t hesitate to ask your provider. Understanding your hormone levels is a key part of managing PCOS effectively.

What Comes After Your Test

Working with Your Doctor on Results

Once your hormonal panel is complete, your doctor will evaluate your hormone levels against standard ranges and diagnostic criteria for PCOS. They’ll also factor in your symptoms, menstrual history, and any ultrasound findings. This helps pinpoint your specific PCOS type while ruling out other conditions with overlapping symptoms, like thyroid disorders or congenital adrenal hyperplasia.

This thorough evaluation helps shape a treatment plan tailored to your needs. Since hormone patterns over time often reveal more than a single test result, your doctor might suggest ongoing monitoring to track changes and assess how well treatments are working.

If your initial results lean toward PCOS but aren’t definitive, additional testing may be recommended. This could include a pelvic ultrasound to check for polycystic ovarian morphology or further blood work, such as thyroid function tests, prolactin levels, or 17-hydroxyprogesterone to rule out nonclassic congenital adrenal hyperplasia. Tests like glucose tolerance assessments and lipid panels may also be ordered to evaluate metabolic health, as PCOS increases the risk of insulin resistance and cardiovascular issues. Regular monitoring of blood pressure, glucose levels, cholesterol, and triglycerides might also become part of your ongoing care plan. These steps provide a foundation for personalized and targeted treatment.

PCOS Treatment Options

Your treatment plan will be designed to address both hormonal imbalances and metabolic challenges. PCOS treatment is highly individualized and may include lifestyle changes, medications to regulate hormones, insulin sensitizers, or weight management strategies. The choice of treatment depends on your specific symptoms, reproductive goals, and overall health.

Since insulin resistance affects up to 70% of women with PCOS, medications like metformin often play a central role. Hormonal contraceptives are commonly prescribed to regulate menstrual cycles, while anti-androgen medications can help manage symptoms such as acne and excess hair growth.

For added convenience, telehealth services like Oana Health offer access to licensed medical professionals who can provide customized care. They also deliver medications directly to your home, making it easier to stay on top of your treatment plan.

Interestingly, studies indicate that up to 70% of women with PCOS remain undiagnosed. Those who receive regular follow-up care often experience better outcomes, including improved symptom management, enhanced fertility, and better metabolic health. Routine check-ins can help identify and address complications early, such as insulin resistance or cardiovascular risks.

Lifestyle Changes That Help

Managing PCOS isn’t just about medications - it also involves meaningful lifestyle changes. Incorporating a balanced diet filled with whole grains, lean proteins, and healthy fats, along with regular physical activity, can make a big difference. Stress management techniques like mindfulness or yoga can also help improve insulin sensitivity, support weight management, and reduce the severity of symptoms.

Even modest weight loss - just 5% of your body weight - can significantly improve both symptoms and metabolic health for women with PCOS. Cardio exercises like brisk walking, swimming, or cycling are especially effective for weight loss and enhancing insulin sensitivity. Adding strength training to your routine can further boost metabolism, build lean muscle, and improve insulin function.

Stress management is another key component. Chronic stress can worsen hormonal imbalances, so practices like meditation, deep breathing, or yoga can help lower cortisol levels and promote overall well-being.

Experts recommend a comprehensive approach that combines medical treatments with lifestyle adjustments and emotional support. Regular monitoring, individualized care, and patient education play a vital role in helping women with PCOS take control of their condition. Lifestyle changes work best when paired with medical treatments, offering a well-rounded strategy to manage symptoms and reduce long-term health risks.
