Abstract
To ensure proper specimen handling for detecting pathogens, like Enterovirus D68 (EV-D68), from home- and self-collection, alternative techniques are needed to ensure safe transport and reliable testing. PrimeStore® Molecular Transport Medium (MTM) may be an option since it does not require cold storage and inactivates virus while preserving RNA for detection. The purpose of this validation study was to demonstrate the ability to detect EV-D68 via rRT-PCR in MTM. Using a quantified EV-D68 positive control standard, MTM limit of detection for EV-D68 RNA is 104 cp/mL and RNA remains stable up to 30 days unfrozen. Positive and negative residual respiratory specimens from the 2018 EV-D68 outbreak were used for clinical testing. There was an 80% positive and 100% negative agreement with samples in MTM compared to reference. This study demonstrates the feasibility of EV-D68 detection from respiratory specimens collected and stored in PrimeStore® MTM, with implications for home- and self-collection.
