Abstract
A filtration device is disclosed for filtering debris from a biofluid sample. In at least one embodiment, the filtration device provides a collection container having a collection chamber defined by a flexible wall, a mouth fluidly communicating with the collection chamber and formed through the collection container at a top end, and a filter device defining a bottom of the collection chamber. A quantitative container has a quantitative chamber in fluid communication with the filter device with the filter device separating the collection chamber from the quantitative chamber. A biofluid sample is introduced into the collection chamber through the mouth, and when the mouth with a collection chamber cap, the flexible wall of the collection container is squeezed to reduce the volume of the collection chamber and force the biofluid sample through the filter device, the filtered biofluid sample thereafter being contained within the quantitative chamber.
