Abstract
When the quantification of an analyte is based on a color change detected by a change in the amount of light transmitted or reflected, undiluted samples often saturate the detection range of the assay. Thus, very often, the sample needs to be diluted for reliable quantification. Disclosed are systems and method, including various configurations of fluidic circuits for us on an optical bio-disc, that advantageously allow the use of undiluted and/or whole blood samples for colorimetric assays on optical bio-disc is described.
