The most interesting part of this article is when they discuss the weakness of antigen testing and states that these tests can produce a False Negative if there isnt enough of the virus in the sample.Quidel antigen test produces a 20% false negative which means 1 in 5 people tested will test negative for covid but they are actually positive. Hopefully this works well in sona favor because of their low limit of detection (LOD). The limit of detection (LOD) is usually defined as the lowest quantity or concentration of a component that can be reliably detected with a given analytical method. In a recent news release sona stated:The Company received confirmation from an independent laboratory that its test achieved a positive response to a recombinant whole spike protein control reagent specific to SARS-CoV2 and matched the limit of detection (LOD) achieved in its own labs. In-house analytical testing has indicated a very high level of specificity to COVID-19, with no false positives being generated. Lower limit of detection will help reduce the False negative results in Sona test which could make it the best antigen test on the market.
