Beta hCG test is considered to be better than fast test in terms of pregnancy detection time and accuracy. And this test accurately determines the concentration of Beta - hCG that the placenta secretes into the mother's blood while the pregnancy test only detects the presence of this substance in the urine.
The hCG beta test is a test to diagnose pregnancy. Based on the concentration of hCG in the blood to check the status of a pregnancy, as well as detect an abnormal pregnancy.
