A system for automatically testing a fluid specimen to indicate the presence of specified chemical components in the specimen. The system utilizes an assaying device having a collection cup and a cap that carries at least one test strip. The device includes an integrated aliquot delivery mechanism actuatable to wet the test strip with an aliquot delivered from the fluid specimen. The assaying device operates in conjunction with an electronic reader device capable of actuating the aliquot delivery mechanism and reading the reaction of the test strip. A reader device defines a keyed receptacle for accommodating a complementary shaped cup housing in a particular orientation. The reader device includes a camera for capturing the image of a test strip, an actuator for actuating an aliquot delivery mechanism, and a microprocessor/controller for (1) controlling the camera and actuator and (2) processing the image.
