I went to the Diabetic Clinic today and did a test involving my old one touch ultra and the new GlucoRX, the result, which was limited to one test, was fairly surprising.
I purposely tried to get my blood sugar a bit higher than I would usually have it to give a wider possible variance.
The hospital result using their specialist test machine where a sizeable blood sample is taken from the thumb into a fairly large sample tube which does HbA1c, blood fat and current blood glucose. This hospital result was not tested using a common (cheap) blood test meter so should be fairly reliable.
Hospital result of 9.6 mmol/l
One Touch Ultra 9.0 mmol/l
GlucoRx 9.2 mmol/l
By my calculation (which could be wrong) GlucoRx has a 4.2% difference
One Touch Ultra has a 6.3% difference
this means that GlucoRx Nexus is as accurate as the hospital meter
this also means that one touch is always low
