Note: In cases of severe hypotension or peripheral circulatory failure, glucose measure-
ment from capillary samples may be misleading. In such circumstances it is recommen-
ded that venous or arterial whole blood be used.

1.  After start-up, the cuvette holder should be in the loading position. The display will  
 

show “READY” and three flashing dashes.

2.  Make sure the patient’s hand is warm and relaxed. Use only the middle or ring    
 

finger for sampling. Avoid fingers with rings on.

3.  Clean with disinfectant and allow to dry or wipe off with a dry, lint free tissue.
4.  Using your thumb, lightly press the finger from the top knuckle towards the tip. 
 

This stimulates the blood flow towards the sampling point.
