Abstract
Provided are methods and devices for separating particulate analytes or aggregates of analytes from a fluid, after the separation medium of the device is saturated with the fluid. The endpoint indicating completion of the separation is determined by saturation; therefore, no precise metering of the fluid sample is necessary. The separated analyte of interest can be detected, quantitated or its migration measured in the separation medium. The measured property of the analyte can then be correlated with a parameter of interest. In some embodiments, the device can be marked to directly read the value of the parameter of interest. In one embodiment, the fluid is blood and the device includes a volumetric capillary reservoir for collecting the blood, a separation paper or indicator strip, and graduations for correlating the migration of red blood cells with hematocrit or hemoglobin concentration. The interface of red blood cells and plasma creates a readable marking that corresponds to percent hematocrit and can be read from the graduations.
