Method of analyzing the composition of bodily fluids
First Claim
1. A system for analyzing a body fluid of a patient, said system comprising:
- a fluid passageway having a patient end configured to provide fluid communication with said body fluid in said patient;
a spectroscopic body fluid analyzer accessible via said fluid passageway, said analyzer having a sample analysis chamber, said system having a sample draw mode in which said system is operable to draw a sample of said body fluid into said sample analysis chamber via said fluid passageway; and
a source of quality control fluid accessible to said body fluid analyzer.

Abstract
A method of analyzing bodily fluids from a patient at the point of care for the patient is provided. The method comprises establishing fluid communication between an analyte detection system and a bodily fluid in the patient. A portion of the bodily fluid is drawn from the patient. The analyte detection system analyzes the bodily fluid to measure a concentration of an analyte. A test is performed on the analyte detection system according to a predetermined schedule to determine if the analyte detection system is properly calibrated. To perform the test a sample of a quality control solution is drawn into the analyte detection system and measured. The test results are compared to a reference range for the quality control solutions. If the measurements are within the reference range, the analyte detection system is permitted to resume analyzing the bodily fluids of the patient.
