Key result
The RT-LAMP assay correctly detected 100% of 84 FMDV positive samples with a detection limit of 10 copies per reaction, demonstrating higher sensitivity than conventional RT-PCR and no cross-reactivity.
Population
139 viral samples including 84 FMDV, 17 CSFV, 10 SVDV, 19 PRRSV, and 9 JEV specimens, as well as FMDV strains.

RT-LAMP may aid FMDV research assays; leaves open clinical adoption without prospective field validation.
RT-LAMP provides a rapid, sensitive, and specific method for detecting FMDV RNA, outperforming conventional RT-PCR in detection limits.
Chen et al. (2011) studied Foot-and-mouth disease virus (FMDV) infection (n=139). Reverse transcription loop-mediated isothermal amplification (RT-LAMP) vs. Conventional RT-PCR was evaluated on Detection of FMDV RNA (sensitivity and specificity). The RT-LAMP assay correctly detected 100% of 84 FMDV positive samples with a detection limit of 10 copies per reaction, demonstrating higher sensitivity than conventional RT-PCR and no cross-reactivity.
