RDT versus PCR
cough, fever
The sensitivity of RDT of more than 95% in patients with VL≥10There was a slight variability in performance between the three different RDTs with STANDARD Q® having a higher sensitivity (93%) than those of PanbioIn our study, the specificity of all three tests was 100%, which is impressive considering the potential for inter-observer variation in RDT test line reading. This observation implies that the assessed RDTs brands are easy to read, and that faint lines can still be easily detected. This excellent specificity, which was also shown in the other studies on high quality RDT, allows to state that there is no need to confirm a positive RDT test result by an additional PCR test.One of the strengths of our study also lies in the fact that the study population represented that of routine COVID-19 diagnostic centres, namely symptomatic outpatients with fever or cough or anosmia/ageusia or symptomatic close contacts. The study was performed at the end-user level in real-life conditions, which is in agreement with WHO recommendations for evaluating the performance of new diagnostic tests [
