When is elevated testosterone not testosterone? When it is an immunoassay interfering antibody
Abstract
A discrepancy between clinical findings and a markedly elevated testosterone (T) level stimulated search to explain this inconsistency. The cause of the falsely elevated T level was determined to be heterophile antibodies from a polyclonal gammopathy in a subject with acute myelogenous leukemia.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
