Hemoglobin sensor
First Claim
1. A device for measuring an amount of hemoglobin in a sample, the device comprising an electrochemical cell having a sensing chamber, a first electrode, a second electrode wherein the second electrode is a distance of less than about 500 microns from the first electrode, an aperture for admitting the sample into the sensing chamber, and a reagent contained within the sensing chamber wherein the reagent is capable of being reduced by hemoglobin to generate an electrical signal indicative of the amount of hemoglobin.

Abstract
The present invention relates to a device and method for measuring hemoglobin in a fluid sample. The device comprises a disposable electrochemical cell, such as a thin layer electrochemical cell, containing a reagent capable of being reduced by hemoglobin. A suitable fluid sample that may be analyzed according the present invention is whole blood. If the hemoglobin to be analyzed is present in red blood cells, a lysing agent may be added to the sample to release the hemoglobin prior to analysis.
