Reproductive hormone test does not require fasting. Sex hormone test is usually performed on the 2nd to 4th day of the menstrual cycle, and the conditions can be appropriately relaxed for patients with amenorrhea. It is also important to take a short break in your seat before the test to maintain emotional stability, and it is preferable to have the blood drawn at 9:00 to 10:00 am. For patients with combined menstrual disorders, amenorrhea, and abnormal uterine bleeding, it is important to actively improve the sex hormone test in order to clarify the specific causes of the disease, so that the doctor can be guided to the next step of treatment.
