Serological distribution of the RVF PT panel sera according to the two commercial kits (a) ID Screen® Rift Valley Fever Competition Multi-species and (b) INgezim FVR Compac.
The star * or. indicate the sera N°8 to 10, corresponding to the repeatability criteria.

Dose-response relationship using the commercial ID Screen® Rift Valley Fever Competition multi-species kit (ID.Vet, France).
(a) ID Screen® Rift Valley Fever Competition Multi-species and (b) INgezim FVR Compac. CP stands for competition percentage, IP for Inhibition percentage. Dash lines correspond to the positive threshold.
Table 3.
Repeatability assessed with either the ID Screen® Rift Valley Fever Competition Multi-species or the INgezim FVR Compac kits, based on the 3 sera included in the panel specifically for that purpose.
Fig 4.
Assessment of the inter-repeatability based on the 3 sera included in the panel specifically for that purpose.
Distribution of the Competitition Percentage (CP, %) or Inhibition Percentage (IP, %), depending on the test used, either ID Screen® Rift Valley Fever Competition Multi-species (a) or INgezim FVR Compac (b). White boxes correspond to inter-repeatability for each of the 3 sera whereas the dotted box corresponds to the global inter-repeatability.
