Human chorionic gonadotropin + β subunit (hCG + β-HCG)
The test is performed to confirm and assess the progress of pregnancy, in the diagnosis of pregnancy complications such as hypertension or premature birth, to determine abnormal HCG levels which may be associated with fetal chromosomal abnormalities, and to differentiate between malignant and benign trophoblastic diseases.
