A method is provided that includes introducing a fluid sample () into a fluid container () of a filtration assembly () and passing the fluid sample () through a porous filter () by distally advancing a plunger () within the fluid container (), thereby capturing, on or within the porous filter () at least a portion of any particulate present in the fluid sample (). Thereafter, a cavity () is created within the fluid container () between a distal end of the plunger and a distal end () of the fluid container () by proximally partially withdrawing the plunger () within the fluid container (), while one or more vacuum-prevention openings () are open. An extraction liquid () is prepared by introducing one or more extraction reagents () into the cavity () and bathing the porous filter (). The extraction liquid () is tested for the presence of a biological target. Other embodiments are also described.

Testing devices

A testing device () is provided for testing for the presence of particulate in a liquid (). The testing device () includes a liquid container () for containing the liquid (); a filter (), disposed in or downstream of the liquid container (); a liquid-pressure source (), which is arranged to apply pressure to drive the liquid () contained in the liquid container () through the filter (); and a filter chamber () that is (a) disposed downstream of the liquid container (), (b) shaped so as to define an inlet (), and (c) in fluid communication with the filter (). Other embodiments are also described.
