Abstract:
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, wherein said preventing comprises complexing said non-selected analyte so that it cannot participate in said reaction and wherein said complexing comprises interacting said non-selected analytes with a polyanion, said polyanion is an anionic polymer, and said anionic polymer has a molecular weight between 50,000 and 8,000 and the non-selected analytes include HDL analytes, VLDL (very low density lipoproteins), ILDL (intermediate density lipoproteins), and chylomicrons (big, tryglyceride-rich lipoproteins).
