Blood cholesterol levels are directly related to the risk of cardiovascular disease. The HDL and Total Cholesterol rapid assays provide semi-quantitative determinations of high-density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) and total cholesterol levels in whole blood obtained from a finger stick. The tests have been designed in a strip format; an enzymatic color reaction from a single drop of blood produces results in approximately three minutes.

The strip contains a sandwich of membranes that perform the following functions: separation of blood cells from serum, collection of serum, reaction of serum with cholesterol oxidase and substrate and substrate color formation.

The membrane sandwich is assembled in such a way that the whole blood sample is applied to the surface of the separator membrane, and the serum produced moves vertically through the sandwich contacting the reagents in successive layers. The substrate color is formed on the bottom layer of the sandwich. The tests are packaged in kits containing finger stick devices and all other necessary accessories.
