Abstract
A lab-on-a-chip cartridge includes a housing defining four separate chambers. A fluid (such as whole blood) flows through one of the chambers and into another one of the chambers, which includes a filter membrane. The filter membrane is rotated to separate a first fluid component (such as plasma) from a second fluid component (such as red blood cells), with the first fluid component passing through the filter membrane and the second fluid component not passing through the filter membrane. The separated first and second fluid components each flow into a different one of the remaining chambers, with the first fluid component contacting a lab-on-a-chip device for analyzing the first fluid component.
