Abstract
A fluid sample collection unit may include a pod configured to receive a plurality of assay pads and a metering stack. The metering stack defines a channel extending longitudinally between an inlet end and dispensing portions. In some instances, the dispensing portions are movable relative to the assay pads, but a support feature within the pod vertically spaces apart the dispensing portions from the assay pads when less than a threshold vertical pressure is applied. In one instance, the pod defines a collection volume, a dispensing volume, and a passage portion, the passage portion connecting the collection and dispensing volumes. The metering stack is at least partially received within the pod, with the inlet end being positioned at the collection volume, the dispensing portions positioned within the dispensing volume above the assay pads, and an air gap being formed within the passage portion around the metering stack.
