&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 multiple purposes, including monitoring patients for retained products of conception and aiding in the diagnosis of various conditions such as gestational trophoblastic disease, testicular tumors, ovarian germ cell tumors, teratomas, and other hCG-secreting tumors. It involves serial measurement of hCG levels to monitor therapeutic response and detect persistent or recurrent GTD or hCG-secreting tumors, but it is not intended for pregnancy detection or monitoring. Outside of pregnancy, abnormal germ cell, placental, or embryonal tissues may secrete hCG, indicating conditions like testicular tumors, ovarian germ cell tumors, and GTD. Successful treatment of hCG-producing tumors should result in a decline in hCG levels, eventually returning to the reference range.&lt;/span&gt;&lt;/p&gt;
