Hcg beta subunit serum

WebDuring pregnancy, free β-hCG appears in the maternal serum earlier than the A subunit, peaking at 9–12 weeks of gestation (later than all hCG). The level of hCG increases rapidly after fertilization, reaches its peak by the end of the 1st trimester, and subsequently decreases to reach a stable level in approximately 20th week of pregnancy. 4 , 8 , 9 WebSerum hCG-beta levels of POD 12 and 14 and the fold increase of hCG-beta levels from POD 12 to 14 significantly predict pregnancy outcomes after fresh and frozen cycles. ...
