Answer

However, false-positive results have been a problem, with some reports of more than 50%. Although this or a positive culture is the case definition for reporting pertussis to the CDC or the World Health Organization (WHO), some are now recommending confirmation with enzyme-linked immunosorbent assay (ELISA) before declaring an epidemic. (Many now consider serologic testing with ELISA to be the criterion standard.)
