University of Rochester (Rochester, NY) researchers developed a technique, using a laser, white light, and a reflective tube, that in 60 seconds or less measures multiple chemicals in body fluids. The technique tests urine and blood serum for common chemicals important to monitoring and treatment of diabetes and cardio- vascular, kidney, urinary diseases, and lends itself to the development of fast batch testing in hospitals and other clinical settings.

The Rochester team measured 11 chemicals in blood serum, including total protein, cholesterol, LDL and HDL levels, glucose, triglyceride, albumin, bilirubin, blood urea nitrogen, globulin, and CO2. In urine, they identified urea nitrogen and creatinine.
