Scientific Notation LODIn the news release they incorrectly state the LOD. If anyone not of a science type or forgot .
limit of detection (LOD) of 2.1 by 102 TCID50 . Does not = 2.1 or 2.1 x 102
This actually mean 2.1 x 10 ^ 2 = 2.1 x 100 = 210
10^2 means 10 to the power of 2 = 100
Sona Nanotech Inc.'s rapid detection, COVID-19 antigen test's laboratory validation studies of performance levels have resulted in a test sensitivity of 96 per cent, test specificity of 96 per cent and a limit of detection (LOD) of 2.1 by 102 TCID50. Sales of the tests will now be permitted under a research-use-only label until full regulatory authority is granted, in relevant territories, at which time the research-use-only label requirement would be lifted, as discussed herein.
