Immunoassay device with improved sample closure
First Claim
1. A device configured to receive whole-blood, comprising:
- a housing comprising an orifice that is in fluid communication with a conduit that terminates at an internal capillary stop; and
a pump configured to displace the whole-blood throughout the device,wherein at least a portion of the conduit is corona-treated and at least a portion of the conduit is coated with a dry reagent mixture comprising at least a water-soluble protein and a polymer containing hydroxyl groups, whereby individual drops of the whole-blood form a contiguous segment of the whole-blood in the conduit.

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.
