title: Development of a Dual Path Platform (DPP®) immunoassay for rapid detection of Candida albicans in human whole blood and serum.
abstract: Candida albicans is an opportunistic pathogen which can lead to Candidiasis and blood-stream infections, resulting in a mortality rate near 40%. Given its high fatality and emerging pathogenicity, there is a strong need for the development of a rapid C. albicans diagnostic assay. Point-of-care devices, specifically lateral flow assays, are an attractive and often employed diagnostic modality for C. albicans detection. However, they lack the required performance characteristics needed for accurate pathogen detection and subsequent treatment options. Thus, we describe herein the utility of the Dual Path Platform (DPP®) device as an immunochromatographic Point-of-care assay for C. albicans. The limit of detection for hyphal and budding C. albicans in DPP® tests are reported to be as low as 7.94 × 10(5) whole cells/mL in human serum. C. albicans cells were detected with up to a 3.9 fold increase in sensitivity on DPP® when compared to conventional lateral flow modalities.
