For a preconception checkup, if you are usually in good health, you can do some routine tests, which usually cost 300-500 RMB. For example, routine blood tests to understand whether anemia and platelets are normal, routine urine tests to see if there are hidden infections in the urinary system, liver function tests and hepatitis B 5 tests to see if there is hepatitis or abnormal liver cell function, electrocardiograms to rule out heart disease, and ultrasound of the reproductive system to understand the thickness of the ovaries and the endometrium and whether there is tubal infection. If you are usually unhealthy and have difficulty getting pregnant after marriage, you will need to do some targeted tests, which will cost a little more, depending on the specific test items.
