|Test||HCG, QUANTITATIVE, PREGNANCY|
NOTE: This procedure has been approved by the FDA only for the diagnosis and monitoring of pregnancy.
|Description||Human Chorionic Gonadotropin (hCG), Quantitative, (Pregnancy), is useful for the early detection of pregnancy and monitoring in vitro fertilization patients. Elevated values serve as an indication of chorionic carcinoma, hydatiform mole or multiple pregnancy. Depressed values indicate threatening or missed abortion, ectopic pregnancy, gestosis or intrauterine death.
Mildly elevated values (5 mIU/ml - 25 mIU/ml) have been observed in postmenopausal women. LH and/or FSH levels can be used for postmenopausal diagnosis.
No sample should be collected on patients receiving therapy with high biotin doses(i.e. biotin therapy for Multiple Sclerosis or oncology patients; skin, hair and nail supplements, or multivitamins containing > 5 mg/day) until at least 12 hours after the last biotin administration. If unsure, or if the clinical picture does not fit the results please contact the laboratory . We have methods to check for biotin interference as well as for any other interferences and for the accuracy of the results.
