New CC #11: Positive HCG in the Non-OB/Non-Gyn CA Patient

HCG is a heterodimeric glycoprotein typically produced by trophoblastic tissue. However, there are occasions where a serum HCG is obtained that remains low level POSITIVE, yet the patient is not pregnant, nor does she have a gynecologic malignancy. Why dose this happen. Not all these instances can be explained by the “PHANTOM” HCG. In this episode, we will review a new Clinical Consensus guideline from the ACOG officially being released in Feb 2026. Like the finding of an aberrant aneuploidy on cell-free DNA testing in pregnancy (NIPT) where the child is found to NOT be affected, where that abnormal result may signal a hidden malignancy, a persistent low level positive HCG that cannot be explained by pregnancy or a gyn cancer may signal a hidden malignancy elsewhere. Listen in for details. 1. ACOG CC #11, February 2026
