Abstract

A sample collection assembly provides for the simultaneous collection of a bulk sample and a drop sample. The assembly includes a specimen collection container for collection of the bulk sample from an insertable probe. A drop sample substrate is positioned across an open end of the container or the closure that is in the open end of the container. The drop sample substrate is puncturable by the probe upon probe insertion. The drop sample substrate includes a drop sample retaining surface for retaining the drop sample upon withdrawal of the probe from the container.

Claims

1. An assembly for collection of a drop sample comprising:

a sample collection container having an opening and a container interior for collection of a bulk sample from a probe withdrawably insertable through said opening; and

a drop sample substrate positioned across said opening and being puncturable by said probe, said substrate including a drop sample retaining surface facing said container interior for retaining said drop sample upon withdrawal of said probe from said container.

2. The assembly of claim 1, wherein said container includes an interior and exterior wall surface and wherein said substrate is an elongate strip having a first portion attached to said exterior wall surface of said container and a second portion positioned across said opening.

3. The assembly of claim 1, wherein said second portion of said strip is removable from said first portion.

4. The assembly of claim 3, wherein said first and second portions are separated by a perforation.

5. The assembly of claim 1, wherein said substrate further includes a specimen impervious surface opposite said sample retaining surface.

6. The assembly of claim 1, wherein said drop sample retaining surface includes specimen retaining liner.

7. The assembly of claim 6, wherein said liner includes a pre-treated filter paper.

8. The assembly of claim 3, wherein said elongate strip includes indicia bearing locations on said first and second portions for providing coordinated identification of said bulk sample and said drop sample.

9. The assembly of claim 1, further including a container closure positionable in sealed relationship within said opening, said closure being puncturable by said probe and said drop sample substrate being positionable over said closure.

10. The assembly of claim 9, wherein said closure includes an upper surface and a central well area, said well area defining a puncturable portion of said closure.

11. The assembly of claim 10, wherein said drop sample substrate is adhered to said upper surface of said closure.

12. An assembly for the simultaneous collection of a bulk specimen sample and a drop specimen sample comprising:

an open ended collection container for accommodating said bulk specimen deposited by a probe inserted through said open end; and

a drop specimen collection substrate positioned across said open end for engagement with said probe so as to collect said drop specimen upon withdrawal of said probe from said container.

13. The assembly of claim 12, wherein said drop specimen collection substrate includes a drop specimen retaining surface.

14. The assembly of claim 13, wherein said drop specimen collection substrate includes a strip, said strip having a first portion attached to said container and a second portion secured across said open end of said container.

15. The assembly of claim 14, wherein said second portion of said strip is detachable from said first portion of said strip.

16. The assembly of claim 15, wherein said first and second portions of said strip include coordinated identifying indicia.
