Free βhCG

Free βhCG

The Fortress Diagnostics Free Beta (β) kit is intended for the quantitative determination of Free βhCG chrorionic gonadotropin subunit concentration in human serum by a microplate chemiluminescence assay. 

Human chorionic gonadotropin (hCG) concentration increases dramatically in blood and urine during normal pregnancy. hCG is secreted by placental tissue, beginning with the primitive trophoblast, almost from the time of implantation, and serves to support the corpus luteum during the early weeks of pregnancy. hCG or hCG-similar glycoproteins can also be produced by a wide variety of trophoblastic and non-trophoblastic tumors.
