TysonBio test strips of different model can not be used interchangeably. It is possible that different model test strip might appear the same in design, color, and dimension, but because of the different reaction mechanism that is internally formulated into different test strip models, thus it is an absolute must to only use the test strip and glucose meter/device of the same model for an accurate testing result. TysonBio does not warrant or guarantee the accuracy of the testing result if different model test strip and glucose meter/device were use interchangeably.

Stating accuracy in a Blood Glucose Monitoring system differs to that of an actual dictionary meaning i.e. "Free from mistakes" or "Exactness". As a common human being, we would take being accurate for literally as if a meter showing a result of 120 mg/dl and this being our blood glucose level is exactly at 120 mg/dl. Whereas in fact a blood glucose meters for home use purpose does not mean it is exact that accurate or the value of testimony showing on the meter is what exactly our blood glucose level is. Various Diabetic Association including American Diabetes Association recommends a meter of those manufacturers where the total error margin of blood glucose level is less than 10%. That means e.g. a blood glucose reading of 70 mg/dl on your meter could actually range anywhere from 63 mg/dl to 77 mg/dl and your meter is still considered accurate. To be sure of your meter is under conformity on accuracy level can best be judged in comparing the result to that of laboratory test.

In terms of Accuracy for a Blood Glucose Monitoring system which is not exact to what it shows as a result but is still considered Accurate as long as it's lower than 10% of total error, Precision is another equally important factor to check if the meter is good enough for use i.e. to see if the meter is able to give same result consistently. As a common rule manufacturer usually test the same blood sample several times to see the variation in result before conforming as a precise meter. In all a meter will be considered good for use if being Precise while also being tested for accuracy level when compared to that of Laboratory results.

As explained accuracy definition of home use Blood Glucose Meters differ from the literal dictionary meaning of "Accuracy". Hence reputed Diabetic Associations as well as different agency's that regulates drugs and medical devices have setup standards to actually determine what type of meters are acceptable and should be acceptable as long as these are under the relevant errors explained in those limitations. For home use meters which have dramatically been improved from old time technology however whatever perfection we try to put in our techniques there is always some errors which do exist. Keeping such things in mind we should try to judge our meters with those under conformity of Standards determined by various organizations like FDA, ADA, CE etc.

There's a lot to consider when discussing the accuracy of blood glucose readings. To secure accurate readings, half of the burden falls on you and half on the manufacturer. It can be frustrating to realize that blood glucose readings aren't always correct. But the bottom line is that it is possible to secure readings that are accurate enough to guide your self-management decisions.

1) Inadequate Blood Samples
Always use fresh capillary whole blood

2) Soiled Meter
DON'T drop or squeeze harshly upon your meter

3) Inproper storage of test strip
Strip should be stored in desiccant vial with cap tightly closed. Temperature and humidity is extremely sensitive to test strip. Always keep strip vial tightly cap in room temperature.

4) Heat or Cold
Appropriate Operating temperature is within 10 to 40°C (50 to 104°F)

5) Defective Strips
If you have doubts about your testing result, always use control solution to verify strip condition. If control test fall out of indicated control range printed on strip vial label, means your strip is defect.

6) Other circumstance
- Insufficient blood lead lower result,
- contaminant on finger causes inaccurate reading.
