Checking the meter the patient is using to test their blood glucose is often beneficial, particularly:
-
Age of machine
-
Ease of use
-
Dexterity problems
-
Quality control checking
-
Frequency of testing
-
Technique used.
-
Blood monitor strips in-date
The range of meters used is extensive and patient preference is the most important factor. Ensuring that the above factors are addressed will promote accuracy and optimal testing.
Type 1 Diabetes
People with Type 1 diabetes should be encouraged to test blood sugars sufficiently often during each day to ensure optimum control according to their insulin regimen Doing a blood test before each injection should be a basic principle. Therefore testing should be four times a day for patients on a basal/bolus regime,and possibly more during dose adjustment or illness.
