Evaluation of suspected interference from heterophile antibodies causing a falsely elevated human chorionic gonadotropin (hCG) result


This test is not to be used for pregnancy testing.


The specimen will be evaluated for potential heterophile antibody interference in the total beta- human chorionic gonadotropin (hCG) immunoassay.


The presence of heterophile interference is not suspected when the alternate platform evaluation, dilution, and heterophile blocking tube pretreatment do not substantially alter measured beta-hCG concentrations.

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

Heterophile antibody evaluation consists of pretreatment with commercial heterophile antibody blocking reagents, testing on an alternate platform, and serial dilution of the sample.
