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

Specimen: Blood

Lab: Quest Diagnostics

Results: Test run Mon-Sat; Report available in 2 business days

Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

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

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.

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

Alternative Name(s) Human Chorionic Gonadotropin (hCG), Chorionic Gonadotropin
