Talk about always having to have the last word I agree it is "simple" but your response does not explain the other two listed ranges nor the gaps between the ranges. The fact that a web search and my personal experience turns up Low, High and Normal control solutions DOES.

Try a web search on "Glucose Control Solution High"

My goal isn't to answer any one person's every question, Frank, but to off my 'experience' - which is what I've been 'encouraged to do more of'. Conjecture's beyond 'my experience' get me into trouble around here... I made the caveat that 'with MY company'. That's my experience.

When you keep asking a 'clarifying question' I will always have a response. That's not needing the last word. I'm glad other companies make multiple test solutions. That seems like a 'great idea'.

I understand those are measured on some kind of control solution but what do the numbers mean? Is it that the strips might measure anything from 39-68 on the same drop of blood? That can't be correct...

Typically, the way these things are figured out: They'll take a relatively known low solution. They will run it thousands of times against many different meters of the same make. They'll gather the data and crunch the numbers to come up with the range. For the low control you speak of, the mean of all the numbers of the data group would be 54. One standard deviation should be, at most, 10% of that (5.4). All control values should be within 2 standard deviations of the mean (5.4 x 2 = approximately 11). Subtract (and add) 11 from the mean to get your range = 43-65. ...Obviously, they allow for a little bit more error.
