The treatment of diabetes begins with knowing what to look for and how to evaluate the information gleaned through testing. When properly administered and interpreted, this information can protect against the adverse effects that diabetic symptoms can cause such as blindness, kidney failure, amputation, and the development of heart disease. Equally the opposite, a misinterpretation of test readings can lead to the loss of valuable time needed to treat symptoms (if the signs are not seen) or the administration of treatment when it is not required. This can cause shock and severe side effects as a result. Accuracy in interpretive analysis is important for everyone concerned with diabetes. It is a life saver, to be sure.
