(A) Comparison of Cq values between samples treated with or without LucigenQE and run by RT-LAMP with 1μl of sample. (B) Comparison of Cq values between RT-LAMP assays run with 1μl straight swab or 5μl of isolated and purified vRNA. vRNA copies/μl are reported for the starting sample concentration before RNA purification and concentration.
