For type 1 diabetics who use blood glucose readings to determine insulin dosing, an accurate blood glucose meter is essential. But, accurate blood glucose meters don't exist. The American Diabetic Association is pushing the FDA for tighter standards.

Th current FDA standards as of 4/19/13 are:

For results at or above 75 mg/dl: 95 percent of meter test results must be within plus or minus 20 percent of the actual blood glucose level.

Example: An actual blood glucose result of 180 mg/dl could show on a meter as any value from 144 mg/dl to 216 mg/dl and meet the standard.

For results below 75 mg/dl: 95 percent of test results must be within plus or minus 15 points of the actual blood glucose level.

Example: An actual blood glucose result of 70 mg/dl could show on a meter as any value from 55 mg/dl to 85 mg/dl and meet the standard.

I just completed a study of 5 glucose meters. I cannot give you the reference because my website is commercial and I will be banned from this website. But, take my word on the results. The inaccuracy problems that exist are mainly due to interference from various chemicals like ibuprophen, vitamin c, etc. In my study I found the Abbott FreeStyle Lite to have the least amount of interference and greatest accuracy.
