Systems and methods for measuring multiple analytes in a sample
First Claim
1. A patient monitoring system for analyzing multiple analytes in a fluid sample, the patient monitoring system comprising:
- a fluid handling system configured to draw a fluid sample from a patient;
a fluid analyzer comprising a sample cell configured to receive at least a portion of the fluid sample from the fluid handling system;
a controller comprising one or more computer processors; and
a non-transitory computer-readable medium encoded with instructions executable by the one or more processors to cause the fluid analyzer to;
measure a first analyte in at least a portion of the fluid sample while the at least a portion of the fluid sample is in the sample cell;
separate the at least a portion of the fluid sample into a plurality of components while the at least a portion of the fluid sample is in the sample cell after measuring the first analyte; and
measure a second analyte in one of the plurality of components while the one of the plurality of components is in the sample cell.

Abstract
Systems and methods for analyzing multiple components of a fluid sample are provided. In certain embodiments, a system can include an analyte detection system configured to measure first analyte data in a first component of a fluid sample received from a patient and measure second analyte data in a second component of a fluid sample. In some embodiments, one or more portions of an optical system is movable with respect to other portions of the system in order to optically and/or electrochemically analyze multiple components of a fluid sample. In other embodiments, optical and/or electrochemical analysis can be performed simultaneously on multiple components of a fluid sample. In some embodiments, a first analyte can be measured in a sample (e.g., whole blood) before the sample is separated into its components (e.g., plasma, red blood cells, etc.), and a second analyte can be measured in a component of the sample after separation.
