Abstract
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.
