Re: Glucose monitor options
Thought I'd post this caution about alternate site testing...doesn't mean you can't ever use it, but important to know when NOT to use it:
Blood sugar results can vary depending on when and where you test your blood. For example, if you get a sample of blood from a testing site on your thigh and your blood sugar is going up significantly at the time, you may get a delayed result. In other words, the result you receive may be what your blood sugar was 20 to 30 minutes ago but it is not accurate for the present moment. You might be able to speed up the process slightly by rubbing the area until it is warm to increase blood flow to that site.
This doesn’t mean you shouldn’t use alternative test sites but they may not give an accurate result when glucose levels are apt to change rapidly, such as after a meal, after taking insulin, during exercise or when you are sick or experiencing stress. When you need an immediate, present-moment result, such as when you suspect low blood sugar, always use a finger test site.
When Not to Use Alternative Site Testing
There are circumstances when alternative testing is not recommended. These include:
•When you have just taken insulin
•During or after exercise
•If you feel you might be experiencing low blood sugar
•When you are preparing to drive
•When you are or suspect that you are ill
Some people with diabetes also have difficulty sensing the bodily signals of low blood sugar. Their hypoglycemic awareness has been blunted over time and they may not be able to accurately assess when blood sugar is going low. Though blood sugar testing is the only way to know for certain whether glucose levels are dropping, alternative site testing is not recommended for people who struggle with hypoglycemic awareness.
