Donna... you did the right thing. Any time you get a "wierd" reading (i.e. somehow may not jive with how you're feeling or waaaay off base from where it should be based on carb/exercise calculations), you should retest. Although getting better and better, the meters we use aren't perfect and "off" readings can happen. Some never have problems with their meters but, an unfortunate few get lemons (just like any other "consumer goods" we buy).
Because I test so often, I was able to immediately see when my meter was giving me problems. I called the OneTouch folks and, after a few tests and questions over the phone, I got a new meter the next day. You may want to call 'em anyway and see what they say?
Sorry to correct your mg/dL to mmol/L conversion calculations, Jeannie, but for those who may want to know...
150's are 8.3-8.8 mmol/L
180's are 10.0-10.4 mmol/L
300's are 16.6+ (not in the 6's,7's, and 10's as mentioned).
To get the equivalent mmol/L, you can multiply the mg/dL glucose value by the conversion factor of 0.05551.
example: 110 mg/dL x 0.05551 = 6.66 mmol/L
Or the less precise way by dividing the md/dL value by 18 to get the equivalent number in mmol/L.
example: 110 mg/dL divided by 18 = 6.1 mmol/L
A good "conversion" info page you may want to check out (has lipid conversions, too):
