Abstract
An assay device and method for measuring the concentration of HDL-associated cholesterol in a blood-fluid sample. The device includes a glass-fiber sieving matrix capable of separating soluble and precipitated material migrating through the matrix, and a reagent reservoir in the matrix, for releasing a reagent effective to selectively precipitate LDL and VLDL particles, while permitting soluble HDL to migrate through the matrix. The glass fibers are coated with a polymer coating to prevent binding of HDL to the fibers in the presence of the precipitating reagent.
