The AMH test assesses ovarian reserve as important in determining a woman's fertility, especially in patients with early ovarian failure. When performing an AMH test, patients should note a number of points to ensure accurate results.
1. What is an AMH test?
AMH stands for Anti-mullerian hormone. It is a hormone secreted directly by the granular cells of the ovarian ovary cyst and is directly related to the number of primitive ovule cysts in the ovaries. Amh amount in which the number of young ovule follicles is present in the ovaries, also known as ovarian reserve. Ovarian reserve is one of the signs of fertility assessment.
AMH levels do not change significantly throughout the menstrual cycle and decrease with age. In healthy women and under 38 years of age, normal AMH levels range from 2.0 – 6.8ng/ml (14.28 – 48.55 pmol/L). Low AMH levels reflect reduced ovarian reserves, higher AMH levels than the above values are also observed in women with polycystic ovaries.
2. Considerations for AMH testing
AMH testing is a fairly new test, which has only been implemented in Vietnam recently. This test plays a very important role in the diagnosis and treatment of rarity, especially before performing ovarian stimulation and in vismation. When performing tests, patients understand some of the following issues:
- When should I get an AMH test? AMH concentrations will be constant, unchanged with the menstrual cycle, so it can be done on any day of the menstrual cycle. This is the advantage of AMH testing compared to previous FSH tests. Therefore, it is much more convenient for the test to assess the fertility of the ovaries. Previously, tests assessing ovarian function (FSH, LH, E2) had to be performed at the beginning of the menstrual cycle (day 2-4);
- When inferentily the patient will be given intravenous blood and can be tested on any day of the menstrual cycle. The test is carried out by the method of immuno-electrolysmization of photo-optics to ensure high accuracy;
- Factors that may affect AMH test results are age, race, smoking status, drinking, obesity, polycystic ovaries, contraceptive use, chemotherapy, radiotherapy, one or both ovaries,… Therefore, before performing an AMH test,the patient should inform the doctor of the above conditions so that the doctor has the appropriate treatment direction.
The AMH test is considered the most accurate test in evaluation of the reproduction function of the ovaries. The level of AMH in the blood of a woman is an index of ovarian reserve and useful in assessing the state of reproduction, especially in patients with early ovarian failure. Just by performing an AMH test, the doctor can estimate the fertility of the patient.
