Successful downstream molecular analyses of viral ribonucleic acid (RNA) in diagnostic laboratories, e.g., reverse transcription-quantitative polymerase chain reaction (RT-qPCR) or next-generation sequencing, are dependent on the quality of the RNA in the specimen. In swine specimens, preserving the integrity of RNA requires proper sample handling at the time the sample is collected on the farm, during transport, and in the laboratory until RNA extraction is performed. Options for proper handling are limited to maintaining the cold chain or using commercial specimen storage matrices. Herein, we reviewed the refereed literature for evidence that commercial specimen storage matrices can play a role in preserving swine viral RNA in clinical specimens. Refereed publications were included if they compared RNA detection in matrix-treated vs. untreated samples. At present, the small number of refereed studies and the inconsistency in reported results preclude the routine use of commercial specimen storage matrices. For example, specimen storage matrices may be useful under specific circumstances, e.g., where it is mandatory to render the virus inactive. In a broader view, statistically sound side-by-side comparisons between specimens, viral RNA targets, and storage conditions are needed to establish if, when, and how commercial specimen storage matrices could be used in diagnostic medicine.
