Human Chorionic Gonadotropin (HCG)
How To Prepare
If a blood sample is collected, you do not need to do anything before you have this test.
If a urine test is done, the first urine of the day is generally the best to use because it has the highest level of hCG. A urine sample collected at least four hours after the last urination will also have high amounts of hCG.
