背景介紹：
前列腺特異性抗原(PSA)是一種由前列腺上皮細胞分泌的33 kDa糖蛋白。在人血清中，前列腺特異性抗原主要與α-1-抗糜蛋白酶結(jié)合，但與其他血清蛋白結(jié)合的程度較小。只有一小部分PSA以自由形式存在(自由PSA)。男性血清總PSA的正常值低于4 ng/mL。PSA濃度升高表明前列腺病理改變，包括良性前列腺增生和前列腺癌。
Prostate specific antigen (PSA) is a 33-kDa glycoprotein secreted by epithelial cells of the prostate gland. In human serum, PSA is primarily complexed with α1-antichymotrypsin, and to a lesser extent with other serum proteins. Only a small portion of PSA is present as the free form (free PSA). The expected normal level of total PSA in male serum is lower than 4 ng/mL. A rise in the concentration of PSA indicates prostate pathology, including benign prostatic hyperplasia and prostate cancer.
