AFP is expressed in fetal livers and in some cases of hepatocellular carcinoma, and may be included in a panel of antibodies for the latter diagnosis, including Arginase-1, HepPar1, polyclonal CEA, etc. It may also be used in the setting germ cell tumors for the identification of yolk sac tumors, though newer markers, such as SALL4, OCT3/4, and Glypican 3 may be a better choice than AFP.
