To perform the test, add 25 ul of sample into all four sample reservoirs. The reader's internal pump moves the samples to the first reagent station for mixing. The pump then moves the samples to the second station for mixing, and lastly into the optical cells of the cartridge to be read kinetically. Sensitivity EU/ml 0.1. 10 single packs of cartridges.
