Evaluation of self‐collected nasal, urine, and saliva samples for molecular detection of SARS‐CoV‐2 using an EUA approved RT‐PCR assay and a laboratory developed LAMP SARS‐CoV‐2 test

The objective of this study was to evaluate the diagnostic accuracy of the TaqPath reverse transcription polymerase chain reaction (RT‐PCR) COVID‐19 kit in paired nasopharyngeal, saliva, and urine samples, as well as a loop‐mediated isothermal amplification (LAMP) SARS‐CoV‐2 laboratory developed test (LDT) in nasopharyngeal samples. Our findings suggest that utilizing saliva samples for RT‐PCR TaqPath and LifeGene‐Biomarks SARS‐CoV‐2 rapid colorimetric LAMP LDT holds promise as an effective alternative method for diagnosing COVID‐19.
