Cholestech Granted U.S., European Patents for HDL Test

June 2, 2005

Cholestech announced that it has been granted a patent by the U.S. Patent Office (6,881,581) and the European Patent Office (EP 1,329,724) for a new method of measuring high density lipoprotein (HDL) in human blood. The company believes that this patent provides a very different approach than those of other existing patents describing the measurement of HDL and that this patent also permits the development of the Cholestech LDX Lipid Profile/Alanine Aminotransferase (Lipid/ALT) cassette by preventing the interference of the HDL chemistry with the ALT assay on the same cassette.
