Abstract
A multilayer test strip that measures concentrations of multiple analytes from a single whole blood sample. The test strip includes a test matrix of several layers held together in constant contact by a test strip holder. The invention is characterized in that it has no moving parts, which is made possible by the novel use of an elongate disbursement layer that spreads blood throughout its entire length, despite having layers with known wicking properties adjacent to and in contact with it. Since the invention relies primarily on a vertical flow format, the test strip is advantageously quite compact. With a single 30-50 microliter sample of blood applied thereto, the novel test strip can provide readings of total cholesterol, HDL cholesterol and triglycerides. From these, LDL can be calculated, thereby providing a full 'lipid panel.' Other analytes such as glucose and ketones may be included in the test strip in addition to or in lieu of one or more of the other analytes.
