Claim:
1. A specimen collection slide comprising: a top rigid layer having a first central opening; a middle rigid layer having a second central opening larger than the first central opening; a filtration media layer for retaining a sample residing entirely within the second central opening of the middle rigid layer, the middle rigid layer protecting said filtration media from damage thereto; a bottom rigid layer having a third central opening substantially the same size as the first central opening; one or more delineated locations on the filtration media layer that identify where one or more samples are to be deposited onto the filtration media, the first central opening of the top rigid layer and the third central opening of the bottom rigid layer exposing portions of first and second sides of the filtration media layer to expose the one or more delineated locations for deposition of said one or more samples directly onto said one or more delineated locations, an external perimeter of said filtration media layer located on said first and second sides, the external perimeter of the first side of the filtration media contacts a portion of the top rigid layer while the external perimeter of the second side of the filtration media contacts a portion of the bottom rigid layer both for securing said filtration media layer within the specimen collection slide, whereby the top, middle, and bottom rigid layers have the same external dimensions, and are securely attached together without damaging the filtration media by attaching the top rigid layer to the middle rigid layer on a first side thereof, and the middle rigid layer is attached at a second side thereof to the bottom rigid layer, said top, middle, and bottom rigid layers being bonded together or ultrasonically welded together to provide the specimen collection slide with a thickness sufficient for handling.
