Here's news for the diabetic. The CAS Trading House has begun marketing German-made gadgets that can help diabetics to keep track of their glucose count without having to visit a pathologist at every sign of discomfort. The two models currently offered are the Accu-Chek Active and Glucotrend. A self-check cannot take the place of thorough, regular examinations by professionals, but can be an efficient way to keep track of your health in between visits.
