Overview
Elevated serum human chorionic gonadotropin is diagnostic of choriocarcinoma.[1][2]
Laboratory Findings
Quantitative serum HCG
- Human chorionic gonadotropin (HCG or b-HCG) is the most common tumor marker test used to diagnose GTD[1]
- HCG is markedly elevated (usu. >10,000 IU)[2]
- HCG is a very sensitive test for diagnosing most gestational trophoblastic tumors. HCG is usually measured in the blood, but it can also be measured in the urine
- HCG levels are much higher in women with complete hydatidiform moles and gestational choriocarcinoma compared to HCG levels in women with a normal pregnancy
- With partial moles, the HCG level is higher than normal, but it is not as high as with other types of GTD
- With placental site tumors, the HCG level may be slightly higher than normal, but it is not considered a good marker for this type of tumor
- An HCG test can help find GTD after pregnancy or miscarriage as this hormone should not be present in the blood or urine soon afterward
Human placental lactogen (hPL)
- Human placental lactogen (hPL) is a tumor marker that may be used to follow women with placental site trophoblastic tumors. High hPL levels are found in women with some types of GTD.
Complete blood count
- Complete blood count can check for anemia from long-term (chronic) vaginal bleeding.
Kidney function tests
Liver function tests
