Buy a female hormone test and check for hormonal imbalance

A female hormone test gives you a snapshot of how your reproductive hormones interact right now. Because these hormones influence each other, the pattern across several values often says more than any single reading.

Symptoms such as an irregular cycle, mood shifts or fatigue can relate to a change in your hormonal balance. A test like this can help make that question more concrete, although the result is not a diagnosis. For busy women, it can be an efficient first step towards understanding what you are noticing, together with a doctor.

This test may suit women who:

• experience an irregular, absent or unusually heavy period
• want to map their hormonal balance as a preventive measure
• have symptoms such as mood shifts, skin changes or fatigue that could relate to hormones
• want to record their cycle-related hormone values as a baseline

You arrange this blood test without a referral online, so there is no need to see your GP first.

This panel measures five hormonal markers in your blood:

• FSH (follicle-stimulating hormone): stimulates follicle growth in your ovaries; the value varies by cycle phase.
• LH (luteinising hormone): triggers ovulation; the ratio between LH and FSH can add context.
• Estradiol (E2): the main form of estrogen, involved in follicle maturation and the buildup of your uterine lining.
• Progesterone: rises after ovulation; the value in the second half of the cycle can suggest whether you have ovulated.
• Prolactin: made by your pituitary gland; elevated values can accompany cycle irregularities.

You can read more on the pages about estradiol (E2), FSH and progesterone.

The result depends heavily on where you are in your cycle at the moment of the blood draw. FSH, LH and estradiol in the early follicular phase (cycle days 2 to 5) can reflect your baseline hormonal activity. As an estrogen test, estradiol focuses on the form of estrogen that helps steer your cycle.

Progesterone around day 21 can suggest whether ovulation has likely occurred, and a consistently elevated prolactin may warrant further investigation. Because these hormones are interconnected, the overall pattern is often more informative than a single value. A doctor can help interpret it in the context of your cycle and symptoms.

For this test, blood is drawn at a certified sample point. There are 700+ locations across the Netherlands, which you choose yourself after ordering, at a time that suits you.

A trained phlebotomist performs the blood draw, which usually takes only a few minutes. Your blood is analysed in a certified lab and your results are typically available within a few working days.

This test can be useful when:

• you have an irregular, heavy or absent period
• you want to understand your hormone profile in relation to your cycle
• you have symptoms such as acne, mood changes or fatigue that could relate to your hormonal balance
• you want to record baseline hormone values for future reference

A female hormone test does not replace a consultation, but it can be a concrete starting point for a conversation with your doctor.

Each marker appears with your own value and the reference range for the relevant cycle phase. Because hormone values change considerably through the cycle, knowing which cycle day your blood was drawn matters; only then is a careful interpretation possible.

Many women want to know what their values actually mean. A number on its own says little: only a doctor can properly interpret your result in the context of your cycle and your symptoms.

Timing is the most important preparation for this test. For FSH, LH and estradiol, measuring on cycle days 2 to 5 is recommended (day 1 is the first day of your period). For progesterone, measuring around day 21 usually gives the most informative result.

If your cycle is irregular, the blood can still be drawn; note the cycle day for your doctor. Do you use hormonal contraception or other hormones? Then discuss with your doctor whether and when measuring makes sense, as this can affect your values.

Your results are available online within a few working days. You see your values with the corresponding cycle-phase reference ranges and a plain-language explanation. If a value falls outside the expected range for that phase, this is highlighted.

Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
