Will Antigen Testing Remain Relevant in the Point-of-Care Testing Environment?

Abstract

Before the molecular age, cell culture was the gold standard for confirmatory diagnosis of viral and atypical infectious diseases. Typical cell culture methodologies are costly, require days (or weeks) for results, and require significant technical expertise. As a result, cell culture is impractical for timely diagnostic testing in most of the health care environments. Traditional bacterial culture methods, also have disadvantages due to the need for incubation, subsequent identification of pathogens, and significant technical expertise. This article discusses the general considerations of antigen and molecular assays and the merits and factors to consider when implementing diagnostic assays for several common pathogens.

Keywords: Antigen assay; Diagnostic infectious diease assay; Molecular assay; Pathogen detection; Point-of-care; Waived testing.
