Pregnancy With Gestational Age (How Far Along)
The Pregnancy with Gestational Age (How Far Along) Test is a blood test that detects the presence and levels of hCG. It not only tells you if you are pregnant, but it also tells you how far along you are in the pregnancy (if you are at least 2 weeks pregnant at the time of the test).
Human chorionic gonadotropin (hCG) is a hormone produced by the placenta during pregnancy. hCG may be detectable in blood or urine around 7-11 days after conception. It reaches peak levels between the 7th and 10th week of gestation, then declines throughout the rest of the pregnancy. hCG can also be produced in other conditions, such as hydatidiform mole, choriocarcinoma, testicular neoplasm, and more.
