How do you test a glucometer to make sure its giving the right reading of blood glucose levels?
We got a note from our school nurse today saying she needs to test out the meter every week. But we have no idea onm how to do it!
All standard glucometers or finger stick blood glucose machines have what are called controls. The controls are reagents for high levels and low levels. The process is called point of care testing. This is important to note because in some states only certain qualified personnel can perform point of care testing. Before the glucometer can be used to check the blood glucose of a real patient these controls should be run on the machine. For example, this procedure should be done first thing in the morning after the physician's office opens or at the beginning of a shift in a hospital setting. The low control is ran first with the low control reagent, then the step is repeated with the high control reagent. The reagents (chemicals) test the device to make sure it is functioning properly.
