What's this test for?

This test is ideal if you're experiencing late, missed, or completely absent periods and want to understand why. It measures the pituitary hormones that control your menstrual cycle, helping identify hormonal imbalances that could be affecting your periods. Many women use this test when their cycles become irregular, they skip periods without being pregnant, or their periods stop altogether.

How should I prepare for this test?

Fasting: 10 hours

Overnight fasting is preferred for this test. This means avoiding all food and beverages except water for at least 8-10 hours before your blood draw. You can drink plain water during the fasting period, and it's best to schedule your test in the morning so fasting overnight is more convenient.

What's included in this test?

FSH LH Prolactin

This panel measures three key pituitary hormones: Prolactin, which controls milk production and can suppress periods when elevated; Follicle-Stimulating Hormone (FSH), which signals your ovaries to prepare eggs and reflects ovarian function; and Luteinizing Hormone (LH), which triggers ovulation and helps regulate your cycle. Together, these hormones reveal whether your pituitary gland is properly communicating with your ovaries, helping identify the root cause of menstrual irregularities.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your hormone levels mean for your menstrual cycle and reproductive health. These notes include personalized recommendations like lifestyle changes, stress management techniques, or whether you should follow up with a gynecologist or endocrinologist. You'll also get the standard lab report and can track your hormone levels over time using our trends feature to see how your cycle patterns change with interventions.
Who should consider getting this test?
This test is ideal for women who have missed multiple periods without being pregnant, experience irregular cycles that vary by more than a week, or have stopped menstruating altogether (amenorrhea). It's also helpful if you're experiencing symptoms like breast milk production when not nursing, difficulty getting pregnant, or symptoms of hormonal imbalance like excess hair growth or persistent acne.
What symptoms indicate I may need this test?
Common signs include missing periods for several months, cycles that are very irregular or unpredictable, unexpected breast milk production or nipple discharge, difficulty conceiving, or losing your period after previously having regular cycles. You might also experience symptoms like headaches, vision changes, low sex drive, vaginal dryness, or hot flashes that suggest hormonal issues affecting your cycle.
How can I naturally support healthy menstrual cycles?
Maintaining a healthy weight through balanced nutrition and regular exercise is crucial, as both being underweight and overweight can disrupt periods. Managing stress through yoga, meditation, or counseling helps balance hormones that affect your cycle. Getting 7-9 hours of quality sleep, limiting excessive exercise, and ensuring adequate calorie intake all support regular menstruation. Avoid crash diets and consider tracking your cycles to identify patterns.
What is prolactin and why does it matter?
Prolactin is a hormone made by your pituitary gland that primarily controls breast milk production after childbirth. When prolactin levels are too high outside of pregnancy and breastfeeding, it can suppress your menstrual cycle and prevent ovulation. High prolactin can be caused by stress, certain medications, thyroid problems, or benign pituitary tumors, and is one of the most common treatable causes of missed periods.
What does high FSH mean?
Elevated FSH levels often indicate that your ovaries aren't responding well to hormonal signals, which can happen as you approach menopause or with conditions like premature ovarian insufficiency. High FSH means your pituitary gland is working harder to stimulate your ovaries, but they're not responding as expected. This can explain irregular or absent periods and may affect fertility.
How often should I retest my hormone levels?
If you're being treated for a hormonal imbalance affecting your cycle, your doctor will typically recommend retesting every 2-3 months to monitor how well treatment is working. If initial results are normal but periods remain irregular, retesting in 3-6 months can help identify patterns or changes. Once your cycle stabilizes, annual hormone testing may be sufficient unless symptoms return or you're trying to conceive.

What this means

Your prolactin levels are elevated above the optimal range. High prolactin can suppress ovulation and disrupt your menstrual cycle, which may explain why your periods are irregular or absent. This elevation can be caused by stress, certain medications, thyroid issues, or other factors that can often be addressed.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
