Patent

CA 2121361

A method is provided for rapidly determining during a saliva specimen collection procedure the presence of an amount of saliva, and for verifying that the sample obtained is in fact saliva. Color indication by dye markers and/or enzymatic activation of color indicators provides an indication that at least a predetermined amount of saliva has been applied to an absorbent and the enzymatic reaction indicates that saliva is contained in the sample collected. Apparatus for collecting a human saliva sample is provided having a dye indicator for signalling the collection of a predetermined sample quantity. alternatively, the apparatus contains a chromogen capable of undergoing chemical conversion upon contact with saliva to produce a color change thereby verifying the presence of saliva as opposed to another fluid.
