&lt;h2&gt;&lt;span style=&quot;color: #33cccc;&quot;&gt;&lt;strong&gt;Overview&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;This test is valuable for diagnosing brain metastases originating from testicular cancer or extragonadal intracerebral germ cell tumors. Human chorionic gonadotropin (hCG) is produced by various tumors including testicular, ovarian germ cell tumors, and gestational trophoblastic disease. Measurement of hCG aids in diagnosing germ cell tumors, especially when present in cerebrospinal fluid (CSF), indicating tumor presence. Different concentrations of hCG in CSF suggest specific tumor types, guiding treatment decisions and monitoring responses. The Roche Beta hCG immunoassay&#39;s specific antibodies can detect various forms of hCG, enhancing diagnostic accuracy.&lt;/span&gt;&lt;/p&gt;
