Before loading the 3-well strip into the two3 device, first ensure the caps of each well are closed. Hold the top of the closed test strip firmly between your fingers and, with a whipping motion of the wrist, flick the tubes 1x. This ensures bubbles are removed from the bottom of each tube.
Note: Bubbles may remain at the top of a tube. This is acceptable. Bubbles at the bottom of a tube, however, are not acceptable.
