For a subset of 1292 specimens, which underwent exactly the same procedures in different countries, we obtained very high specificity (98%) and positive predictive value (PPV=99%), while the sensitivity was 87%, with a negative predictive value NPV=70%, Stratification of RT-PCR data showed superior sensitivity achieved with an RT-PCR cycle threshold (Ct) below 35 (97%), which decreased to 60% above 35. In this field trial, RT-LAMP appears to be a reliable assay, comparable to RT-PCR, particularly with medium-high vir
