A dry mouth test is provided comprising placing a wickable test strip in the mouth of a subject to collect salivary fluid. Distance migrated by the saliva over a specific period of time correlates with the production of saliva and dryness of the mouth. A marker dye is optionally used on the strip which co-migrates with the saliva front and aids in indicating the distance saliva migrates on the strip. A graduated migration scale is printed on the strip to indicate the distance traveled by the saliva. Saliva production is measured with or without stimulation of the salivary glands.
