Hormone 6 test is a common test in gynecology and endocrinology, and the test should be performed on an empty stomach to ensure the accuracy of the test.

If the test is performed on an empty stomach, there will be no errors in the test results due to the influence of food, and it can more accurately reflect the basic functional status of the ovaries. The best time to have the hormone 6 test is 3-5 days after the menstrual period, from 9-10 am on an empty stomach, because the hormone levels are closest to the basal state during these days and the test results will be more accurate. If the patient has irregular menstruation and does not have menstruation for a long time, ultrasound examination can be performed first. If the thickness of the endometrium is around 0.2cm, blood can be drawn directly for examination; if the thickness is more than 0.2cm, medication can be used to induce menstruation under the guidance of the doctor first, and the examination can be performed after the menstruation comes.

In addition to fasting before the blood draw, care should be taken not to overexert and exercise strenuously, and the blood should be drawn after at least half an hour of rest at the hospital; 3.
