I'm confused...I think I need to go to bed.

Anyways, when I fill the syringe up with #3 I am lining the bottom of the plunger up with the 1ml mark. Is this incorrect? Should I be lining up the liquid with the 1ml level?

It just seems like if I line it up with the plunger and I do the test 3 times I get three different numbers. While I may be using the same amount of fluid each time, the air bubble throws off where the plunger is, which if I read the instructions correctly, is the number you use to get your result. Yes? No?
