Marker for testicular tumor is

Tumor markers of Germ cell tumors of the testis Beta HCG Alpha feto protein (AFP) LDH Beta HCG - concentration is increased in both seminoma & non-seminoma AFP - concentration is increased in only non-seminoma LDH - is increased in both, it is not as specific as either of AFP or Beta HCG. So both b hCG and AFP are markers for testicular Ca, but if we have to choose one option, we would go for b hCG as its seen in both seminomas as well as non-seminoma Some other tumor markers for testicular Ca (but not imp.) are Placental alkaline phosphates (PLAP) Gamma-glutamyl transpeptidase (GGT)
