ABSTRACT

Tests for glucose in urine undoubtedly are done more frequently than any other single chemical or biological urinary measurement. "Honey urine" has been known from very early times and was recognized as possessing a sweet taste and having a unique attraction for insects. Glucose is of prime importance in the human body and is a critical intermediary in microbial, plant, and animal metabolism. During fasting, the concentration of glucose in the blood is ordinarily between 65 and 80 mg/100 ml. In the process of the formation of glomerular filtrate in the kidney, the glucose concentration does not decrease. The clinical utility of urine sugar tests in screening, aiding in the diagnosis, and in monitoring the treatment of diabetes is well-recognized. Proficiency tests are useful for either laboratories, physician's office testing, or patient testing. Obviously, the proficiency test by the patient can be somewhat less formalized than that involving a laboratory.
