How different are your readings? I've never really done duplicate or triplicate readings on my tests. Hmm, I'm totally going to go check this!!

Tonight I got 340, 360, and 390. The bubbles each time were of different sizes. If your bubble is bigger one test then the next you have a different volume of solution in the syringe, right? Or am I crazy?
