Abstract

A sample collection device for a fluid includes: a substantially disk-shaped body having a periphery; a capillary channel extending through the body and bounded by the periphery, having a first end and a second end, wherein the first end is adapted to draw the fluid into the channel by capillary action; a sample collection well located in the vicinity of the second end and in fluid communication with the capillary channel; and an axis of rotation extending through the center of the disk and which is substantially perpendicular to the major surface of the disk-shaped body. In a preferred embodiment, the sample collection device is adapted to rotate about the axis of rotation within a cartridge having a housing comprising an air vent in fluid communication with the capillary channel when the disk is rotated in a first position.
