Reference: Roche BHCG Package Insert

hCG can serve as a screening assay for pregnancy. However, early pregnancy may not give a positive hCG test result. In addition, some non-pregnant women may have a hCG result slightly higher than the reference limit. Careful interpretation of the hCG with clinical history is required to determine whether the patient may be pregnant.

Additional information:
HAMA (human anti-mouse antibodies) interfere with this test. Patients who have been treated with mouse monoclonal antibodies should not be tested with this procedure.

Test includes:
Beta human gonadotropin (BhCG), quantitative.
Methodology:
Electrochemiluminescence Immunoassay
Synonyms:
Beta sub, Quantitative Pregnancy, Beta HCG, HCG, Pregnancy Test
HCG BETA,SERUM; BHCG
BETA HUMAN CHORIONIC GONADOTROPIN, TOTAL
Clinical significance:
hCG is a placental hormone which is secreted to detectable levels during the first two weeks of pregnancy.

Neoplasms such as hydatidiform mole and choriocarcinoma may produce hCG ectopically. The test detects the entire hCG molecule ("total beta hCG").
