Abstract
In one embodiment, a test strip for testing for cholesterol-related blood analytes in whole blood includes a red blood cell separation layer, the red blood cell separation layer separating red blood cells from a blood sample applied to the test strip as the blood sample flows downward through the red blood cell separation layer. The test strip further includes a reaction layer receiving the blood sample from the red blood cell separation layer, the reaction layer including POE-POP-POE block copolymer, a surfactant, and a reflectivity changing reactant, the POE-POP-POE block copolymers solubilizing essentially only non-LDL cholesterol analytes, the non-LDL cholesterol analytes reacting with the reflectivity changing reactant in order to change a reflectivity of the blood sample.
