High-density lipoprotein assay device and method
First Claim
Patent Images
1. An assay device for measuring serum cholesterol associated with high-density lipoproteins (HDL) in a blood fluid sample also containing low density lipoproteins (LDL) or very low density lipoproteins (VLDL), the device comprising:
- a. a sample distribution matrix for distributing the blood fluid sample in said assay device;
b. a reagent pad containing a reagent effective to selectively remove non-HDL lipoproteins from the fluid sample; and
c. an HDL assay element in which HDL concentration can be assayed, in direct contact with said reagent pad;
wherein said reagent pad may be brought into fluid communication with said sample distribution matrix.

Abstract
An assay device and method for measuring the concentration of HDL-associated cholesterol in a blood-fluid sample are described. The assay design is such that removal of non-HDL lipoproteins from a sample and assay of HDL cholesterol in the sample occur without interruption of the assay. The device also prevents interference by reagents used for the HDL assay with other assays carried out on the same sample.

8. A method of measuring serum cholesterol associated with high-density lipoproteins (HDL) in a blood fluid sample also containing low density lipoproteins (LDL) or very low density lipoproteins (VLDL), the method comprising:
-
a. applying said blood fluid sample to a sample distribution matrix; b. transferring said blood fluid sample from said matrix to a reagent pad containing a reagent effective to selectively remove non-HDL lipoproteins from the sample; c. transferring said sample to an HDL assay element, which is in direct contact with said reagent pad, and in which HDL concentration can be assayed; and d. determining the content of HDL lipoproteins in said sample; wherein fluid communication is selectively establishable between said sample distribution matrix and said reagent pad. - View Dependent Claims (9, 10, 11, 12, 13, 14)
