Abstract

A specimen collecting and testing device has a housing containing a test membrane. An elongated handle having a foam member is slidably received in the housing. Once the foam member obtains a specimen, the specimen is expelled from the foam member and delivered to a fluid chamber positioned along the test membrane. The device is then positioned horizontally and specimen that collects in the fluid chamber passes through an aperture in the fluid chamber and onto the test membrane located beneath the aperture. The test membrane may then be observed for optical changes in the case of an instant-type test, or removed for further processing. The device is particularly useful for collecting samples of urine or oral fluid for use in drug testing, pregnancy testing and the like; for testing of specimen for any of a variety of analytes such as HIV, hepatitis B, hepatitis C, etc.; and, for collecting samples of DNA for PCR testing.
