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; and
a fluid analyzer configured to receive at least a portion of the fluid sample from the fluid handling system, the fluid analyzer further configured to;
measure a first analyte in at least a portion of the fluid sample;
separate the at least a portion of the fluid sample into a plurality of components; and
measure a second analyte in one of the plurality of components;
wherein the at least a portion of the fluid sample that is separated is the same portion of the fluid sample that is used to measure the first analyte and is used to measure the second analyte.

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.
