1. A fluid sample collection device, comprising:
- a housing comprising at least one substantially planar surface and at least one slidable sealing element,wherein said sealing element comprises prongs separated by a gap permitting slidable movement of said sealing element relative the substantially planar surface,wherein said substantially planar surface has an orifice that is in fluid communication with an internal fluid sample holding chamber which terminates at an internal capillary stop, andwherein said slidable sealing element is slidably movable over the orifice of the fluid sample collection device prior to insertion into a reader and over at least a portion of the substantially planar surface in a way that displaces any excess fluid sample away from the orifice, seals the fluid sample within the holding chamber, and inhibits the fluid sample from prematurely breaking through the capillary stop to an analysis location, wherein the device is configured to expel a metered portion of the sample through the capillary stop.

Abstract
An apparatus and method for sealing a fluid sample collection device, comprising loading a fluid sample collection device with a fluid sample, said device comprising a housing having at least one substantially planar surface that includes an orifice in fluid communication with an internal fluid sample holding chamber which terminates at an internal capillary stop; and slidably moving a sealing element over at least a portion of said substantially planar surface in a way that displaces any excess fluid sample away from the orifice, seals the fluid sample within said holding chamber, and inhibits the fluid sample from prematurely breaking through the internal capillary stop.
