There are several clinical methods to detect pregnancy quickly: firstly, blood HCG test, if the blood HCG is >10mIU/ml, it indicates pregnancy. Secondly, urine HCG test can be done by urine. In clinical practice, if the morning urine test is done after 35 days of menopause, it can also be done quickly to find out whether pregnancy is present or not. The fastest is the urine HCG test, which will give results in a few minutes; the blood HCG test, which will give results at 3:30 pm the same day if blood is drawn at 9 am; and the ultrasound, which will also give results in a few minutes.
