Abstrakt: Objectives: The goal of this study is to assess the ability of the T2Candida platform (T2 Biosystems, Lexington, MA) to accurately identify Candida species from pediatric blood specimens with low volumes.
Methods: Whole blood from 15 children with candidemia was collected immediately following blood culture draw. The amount of blood required by the system was reduced by pipetting whole blood directly onto the T2Candida cartridge. Specimens were subsequently run on the T2Dx Instrument (T2 Biosystems).
Results: The T2Candida panel provided the appropriate result for each specimen compared with blood culture-based species identification and correctly identified 15 positive and nine negative results in 3 to 5 hours. While the time to species identification for blood culture was not reported, the T2Candida results include species data.
Conclusions: T2Candida can be used to efficiently diagnose or rule out candidemia using low-volume blood specimens from pediatric patients. This could result in improved time to appropriate antifungal therapy or reduction in unnecessary empirical antifungal therapy.
