A fluid sampling and analysis system. The system comprises a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid of a patient; a sample analysis chamber accessible by the fluid handling network; and a pump unit in operative engagement with the fluid handling network. The pump unit has an infusion mode in which the pump unit is operable to deliver infusion fluid to the patient through the patient end; a sample draw mode in which the pump unit is operable to draw a sample of bodily fluid from the patient through the patient end, and provide a portion of the sample to the sample analysis chamber; and an optical calibration mode in which the pump unit is operable to supply calibration fluid to the sample analysis chamber. The system further comprises a spectroscopic analyzer configured to obtain spectra of the contents of the sample analysis chamber; a processor in communication with or incorporated into the spectroscopic analyzer; and stored program instructions executable by the processor to obtain a measurement of one or more analytes in the portion of the sample from the spectra. |
