Result Interpretation

Results of the HCG-TM test cannot be interpreted as absolute evidence of the presence or absence of malignant disease. This test should not be used in determining or monitoring pregnancy; for that purpose, use the HCGQ test instead.

Newborns will have detectable levels of hCG (≤ 50 mIU/mL) at birth which decline to undetectable by the third month of age.
Peri- and post-menopausal females often have mildly elevated hCG levels (usually less than 14 mIU/mL), that are constant over time.

The HCG-TM test is performed on Roche instruments using an electrochemiluminescence immunoassay that detects intact hCG, “nicked” forms of intact hCG, the beta-core fragment and the free beta-hCG subunit. HCG concentrations obtained from different assay methods or instruments cannot be used interchangeably. The performance characteristics of this assay as a tumor marker have been evaluated by the Northwell Core Laboratory and is not FDA approved.
