Alkaline phosphatase.placental Ag

This specialized pathology test uses immunostaining to detect placental alkaline phosphatase (ALP) antigen in tissue samples. Placental ALP is an enzyme found in the placenta and is sometimes expressed in certain cancers, particularly germ cell tumors. Finding placental ALP in tumor tissue helps diagnose specific cancer types and guide treatment decisions. This test is used by pathologists during cancer diagnosis and is valuable for distinguishing between different tumor types and identifying tumors of germ cell origin.
