Abstract
Devices and methods for utilizing dry chemistry dye indicator systems for body fluid analysis such as glucose level in whole blood are provided by incorporating an indicator in a bibulous matrix contained inside a hollow fiber capillary tube adapted to wick the fluid sample into the tube to wet the matrix and indicator system. The devices also enable visual or meter reading of the indicator by positioning the hollow fiber capillary tube in a housing having an optical opening adapted for receiving light form a source and directing the light to the capillary tube and for directing the light reflected therefrom to a detector. An advantage for the individual user is the small fluid, e.g., blood sample required, which enables the user to avoid using finger tip sticks for samples. Another aspect of the device provides a determination of and correction for hematocrit level in whole blood in combination with indicator indication of analyte concentration. The devices provided are low cost due to efficient manufacturing.
