Abstract:
1. A vertical flow test strip for use in the direct detection of cholesterol produced from low density lipoprotiens in a whole blood, plasma or serum sample, the test strip comprising: a) a red blood cell blocking membrane for blocking or slowing the progress of red blood cells through the test strip; b) a cholesterol detection membrane for providing a color change in the presence of cholesterol; and c) in said test strip between said red blood cell membrane and said cholesterol detection membrane, a supply of combination of reagents that can bind with non-LDL lipoproteins to block the cholesterol in said non-LDL lipoprotiens fromb eing measured in said chloesterol detection membrane while selectively permitting low density lipoprotein cholesterol (LDL-C) to be directly measured.
