Abstract: The single-use disposable spectrophotometer described herein can measure one or more blood chemistry analytes from a drop of whole blood. A passive filtration system takes whole blood and delivers plasma along with a dissolved reporter molecule to one or more spectrophotometers which can operate with narrow band optical spectrum centered on an optical detection frequency. The spectrophotometer detects the changes in absorption of the plasma as a result of a chemistry reaction to determine the concentration or activity of one or more analytes.
