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?

No no you're totally right the first time, you line up the plunger not the liquid and then you read where the plunger is. The air bubble shouldn't throw off where the plunger should be at all.

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!!
