Orderable Test Description
Prostate specific antigen (PSA) is a glycoprotein with a molecular weight of 33-34kDa. It is restricted to the cytoplasm of acinar and ductal epithelia of normal, benign or malignant prostate tissue. Furthermore, PSA from prostatic cancers has been shown to be immunologically and biochemically similar to that of normal prostate tissue. The antibody reacts against primary and metastatic prostatic neoplasms, but not against tumors of non-prostatic origin. This antibody is useful for determining if an isolated metastasis is of prostatic origin.
