What to know about HCG pregnancy tests
An HCG pregnancy test checks human chorionic gonadotropin (HCG) levels in the blood or urine. HCG tests can detect elevated HGC levels to determine if a person is pregnant.HCG tests can also determine if a person’s body is producing the correct levels of certain pregnancy-related hormones. Typically, HCG levels increase steadily during the first trimester, peak, then decline in the second and third trimesters as the pregnancy progresses.Doctors may order several HCG blood tests over several days to monitor how a person’s HCG levels change. This HCG trend can help doctors determine how a pregnancy is developing.
