Anti-Mullerian Hormone

Measures a hormone used as one of the markers of ovarian reserve.

As one component of ovarian reserve assessment in the appropriate clinical context.

1. Check in advance whether the time of day, the day of your menstrual cycle or other timing matters.
2. AMH can often be drawn on any day of the cycle, although hormone treatment and clinical circumstances can affect interpretation.
3. Tell your doctor about hormone preparations and dietary supplements; do not change your treatment on your own.
4. Stay calm before the blood draw and keep to the time agreed with you.

Fasting is often not necessary for this test alone. If other tests have also been ordered, or your doctor has prescribed specific preparation, follow the agreed rules.

A specific time is generally not required. If your doctor has set a different time, follow those instructions.

• Hormone preparations and supplements
• Blood draw time or cycle phase, when relevant
• Immunoassay interference, including biotin on some platforms

Venous blood — serum or plasma, depending on the method

The blood sample is collected by a qualified staff member. The tube type, required volume, and processing and storage conditions are set by the laboratory's specific method. You do not need to store the sample yourself.

AMH is one of the markers for assessing ovarian reserve; on its own it cannot predict the chance of pregnancy. The meaning of a high or low result depends on age, symptoms, the method used and the reference interval.

If you are pregnant or have severe abdominal pain, unusual bleeding or significant hormonal symptoms, see a gynecologist/endocrinologist; with emergency signs, seek care immediately.

Do not stop treatment on your own. Confirm the final test conditions with the laboratory.
