TEST DETAILS |
|||||||||||||||||||||||||||||||
Interpretation guide: |
Males: < 2mIU/mL. Women (nonpregnant): <= 1 mIU/mL (premenopausal), <= 7 mIU/mL (postmenopausal) Beta hCG versus Gestational Age
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. |

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"). |
