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 a porous membrane with a skin side which enables separation of whole blood and visually reading the indicator without removing the red blood cell portion of the blood from the membrane. The devices also enable visual reading of the indicator by use of a cellulose fiber glass composite matrix which provides separation of whole blood in a lateral flow of the blood through the matrix from the input area to a test area of the matrix. Another aspect of the device provides a determination of hematocrit level in whole blood by measuring flow rate through a restricted passageway in the device.
