It is difficult to recall a time when doctors and patients had trouble tracking the presence of glucose and other substances in urine and blood. Lack of sufficient measurement tools made it difficult to manage a host of diseases, including diabetes as well as other metabolic diseases and kidney and liver conditions. Today, self-management of these diseases is an easier process because of the development of diagnostic test strips by Alfred and Helen Free and their research team at Miles Laboratories.
