The Estrogen VI test is performed on the 2nd-5th day of menstruation, on an empty stomach. Sit still for half an hour as much as possible during the blood test to avoid excessive walking and straining that may affect the Estrogen VI results. At the same time, when you have your blood drawn for the estrogen test, try to have it done between 9 and 11 pm, as this will increase the accuracy of the estrogen test. There are some women who have not had their periods for a long time and have no way to resume normal menstruation due to endocrine hormone disruption. After the test results come out, you must make a detailed judgment with the reference range, and according to the situation, symptomatic medication can be administered.
