Erroneously high Dextrostix values caused by isopropyl alcohol.

Glucose oxidase peroxidase chromogen reagent (Dextrostix) in combination with the Eyetone colorimeter has become increasingly popular in the rapid detection of hypoglycemic states in the newborn. Although the reliability of this system is well documented, there are several factors which can compromise the accuracy of the procedure. One such problem is the glucose reading given after a blood-alcohol combination is tested. By decreasing the light reflected from the strip, the optical electrical interpretation of the Dextrostix is altered by alcohol such that there is an apparent increase in the glucose level as read by the eyetone meter.
