One-third of all testis tumors secrete HCG which can be detected in the serum by radioimmunoassay. beta-HCG levels can be used for diagnosis and follow-up of testis tumors. Seminomas with elevated serum beta-HCG levels probably have nonseminomatous metastases.
所有睾丸肿瘤中有三分之一会分泌人绒毛膜促性腺激素（HCG），可通过放射免疫测定法在血清中检测到。β-HCG水平可用于睾丸肿瘤的诊断和随访。血清β-HCG水平升高的精原细胞瘤可能有非精原细胞瘤转移。
