NON-PRECIPITATING BODILY FLUID ANALYSIS SYSTEM
First Claim
Patent Images
1. A method of determining a characteristic of low density lipoprotein (LDL) from a plurality of analytes in a bodily fluid, said method comprising:
- providing said bodily fluid containing said LDL and one or more non-selected analytes;
providing a dry test strip having a well with porous layers within said well that allow said analytes to pass creating a vertical column of said analytes having a defined volume;
applying said bodily fluid to said well in said dry test strip; and
reacting said LDL in the bodily fluid with a reactant in said dry test strip to provide an indication of said characteristic while preventing said one or more non-selected analytes from participating in said reaction, without precipitating said one or more non-selected analytes.

Abstract
A bodily fluid analyzer including a dry test strip impregnated with a reagent providing a non-precipitating reaction to exclude non-desired analytes. The reagent complexes the non-desired analytes so they remain in solution but cannot participate in the test reaction. Red blood cells are removed from the detection area by slowing their vertical movement and stopping flow when the detection membrane is saturated.

22. A dry test strip for determining a characteristic of a selected analyte in blood, said dry test strip comprising:
-
a reaction layer including chemicals that will react with said blood to provide a characteristic of a selected analyte in said blood; and said dry test strip further containing a complexing chemical that complexes non-selected analytes to prevent them from participating in said reaction without precipitating them. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
