What is the normal variability for a blood glucose meter? I recently bought a meter of low blood glucose (the TrueTrack Smart System "kit) on the internet to check my blood glucose levels after a report was diagnosed with type 2 diabetes. Since I have no symptoms and 'm not overweight I am expecting to be reassured, but I found my 8 am fasting blood glucose over several days seemed to range of 98-124 indicating potential prediabetes. However, this morning, I became confused about obtaining a reading of 144 despite not having eaten for more than 12 hours. I decided to do several tests in a row and the results were: 144 130 117 111 126 110 104. I am sure my fingers were very clean and dry and of course use new strips and lancets every time. The meter does not come with a solution of glucose control, but does have a test card that you can insert into wearing a band that reads, "OK". My question is, what is the normal range of reproducibility you can expect to readings from a meter, and do I consider these results and throw?
The FDA allows the house meters vary up to 20%.
Even the best meters give a fairly high variation in tests of this kind.
Also, remember that the blood sugar is a moving target, so that even a few seconds later, your level may be different.
I have a OneTouch Ultra2 blood glucose that comes with the control solution. But you have a wide range of acceptable test results of control, something like 100-140. The FDA requires that the accuracy of + / - 20%. My reading of control solution is 120, but what do you say? Flag
You must contact the company for the answer to that percentage. However, a true reading of blood glucose is done after 14 hours of fasting. when you wake up, do not test your blood right away. wash your face, dress, and then do your blood test. This allows your muscles to be moved shortly before the test. lower your blood sugar, carbohydrates and starch, atlest of brisk walking 30 minutes a day. The best way to test your blood sugar is to go to a doctor and ask for hemoglobin A1c test. This will show you how blood glucose levels were made for 90-120 days.
Dodge Sounds to me, if you invest in these utensils, so you can get a good start with. In Australia, our blood glucose measurement percentile between 5 and therefore is allowed six years, six to seven is a gray area, more than seven, you are probably diabetic.
You can not expect a cheap meter to be absolutely right on. They usually demand somewhere on the way the meter is accurate.
But a range of 104-144! It's pretty useless! If you can not measure your BG unless there is not much interest to the test! I brought him back to the shop or call the manufacturer and ask them to replace it.
Well, I do not worry about not having control solutions and your range is rather wide (104-144) after fasting for 12 hours you should be below 110 or more, depending on your monitor. Another consideration is, some machines nowadays do you remove the first drop of blood, then use the second as it will give you a more trustworthy result. This could explain the results of your eractic. one more point I want to do .... if you have not received a diagnosis of diabetes and no symptoms, I would not be obsessed by your blood sugar daily. But I want to go see a doctor and ask his opinion. Hope this helps.
