hCG, Quantitative, Serum (Human Chorionic Gonadotropin)
Fasting Required: No

Specimen: Blood

Results: 3-5 Business Days

Description:
This test can be used for the early detection of and on-going monitoring of pregnancy. Elevated hCG concentrations not associated with pregnancy are found in patients with tumors of the germ cells, ovaries, bladder, pancreas, stomach, lungs, and liver. This test may be ordered at regular intervals to monitor the effectiveness of treatment for these conditions and to detect tumor recurrence.

Methodology
Immunoassay (IA)

Limitations
Heterophilic antibodies may produce low false-positive results; urinary hCG is negative if "phantom" hCG is suspected. Pituitary secretion may be a source of low level hCG in post menopausal women

Values from different assay methods may vary. The use of this assay to monitor or to diagnose patients with cancer or any condition unrelated to pregnancy has not been cleared or approved by the FDA or the manufacturer of the assay

Clinical Significance
hCG may reach detectable limits within 7-10 days of conception. hCG is produced by the placenta and reaches a peak between the 7th and 10th week of gestation. hCG is a glycoprotein hormone produced by the syncytiotrophoblast of the placenta and secreted during normal pregnancy and with pathologic conditions such as hydatidiform mole, choriocarcinoma and testicular neoplasm. Order hCG, Total, Qualitative, Urine, if hCG serum result is inconsistent with clinical presentation.
