Cuba has its own blood-glucose monitoring system SUMA SENSOR SXT. For obtaining the Sanitary Register it was necessary evaluate the performance of the system in lay users. This was aimed to demonstrate the capability of these people to use the system, arriving to accurate results after teaching of healthcare professional and having the instructions of the system.

The evaluation was performed according to the ISO 15197:2003(E) conceived for this sort of studies. Diabetic children were tested by their parents and the results were correlated with those ones obtained for the healthcare professionals. Likewise the Control Solution, included in the system, was also proved. The information was collected using an inquiry for arriving to conclusions.

The statistical parameters had an expected behaviour, the correlation coefficients for the blood samples and the Control Solution were 0,995 and 0,980 respectively and the curve slopes were 0,994 and 1,003. These results demonstrated a good correlation among the test by parents and healthcare professionals, with blood samples and with the Control Solution.

Summarizing, once proved a good correlation among the results by lay users and by healthcare professional, we have concluded that the system can be handled by lay users, thus, it can be used as a self-testing with all security.
