摘要： An apparatus and a method are disclosed for providing point of care testing for osmolarity of a bodily fluid. An apparatus (26) is disclosed as having a sample-receiving chip (2) with a fluid pathway passing through it, for receiving and testing a sample fluid. The invention permits osmolarity testing of a sample fluid wherein the sample fluid has a volume of less than approximately 30 nL, and implements a method and device to measure fluid osmolarity in a clinical setting quickly and accurately, while also reducing evaporation of the fluid.
