Following this, the laboratory investigations revealed that the tumor marker CA-125 value was 23.16 U/mL, lactate dehydrogenase, which is used as a marker for tissue damage, lay in the normal range with a value of 150 U/L, alpha-fetoprotein (AFP) tumor marker value 8.28 ng/mL was found to be within normal limits, and beta-human chorionic gonadotropin (B-HCG) levels were within normal limits < 2 mIU/mL indicating negative pregnancy test but the elevated level of inhibin B of 500 pg/mL confirmed the diagnosis of GCT. Here, AFP is linked to neoplasm.
