ABSTRACT:
A saliva testing device includes a sample container opened at one end, a tube, a piston, a holding reservoir and a filter. The piston is fixed to a first end of the tube on a first side of the piston and has a hole in fluid communication with the tube. The piston fits closely and slidably within the sample container. An absorbent pad is affixed to the piston on a second side thereof in fluid communication with the hole in the piston. The holding reservoir is in fluid communication with a second end of the tube. The filter is in fluid communication with a second end of the tube. The absorbent pad receives a sample of fluid to be tested. When the piston is slidably inserted into the sample container, a pressure is generated forcing the saliva of fluid into the holding reservoir through the tube.
