If the HCG is abnormally high in the absence of pregnancy, it is likely to be choriocarcinoma, which must be ruled out clinically and continued blood tests are recommended. If HCG continues to be elevated, it may be clinically indicative of choriocarcinoma, and it is recommended that adequate attention be paid and timely management and treatment be given. Since HCG is clinically specific, it must be related to pregnancy to cause an increase in HCG. If pregnancy is ruled out, only choriocarcinoma will cause an increase in HCG. In addition, if the HCG test is done about 20 days after the abortion, it will also be increased because the HCG will not drop to normal in a short period of time.
