  • Patent number: 6150178
    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 housing is moved with respect to the handle and the foam member is moved inside the housing and slid past the test membrane. In so doing, specimen is delivered to the test membrane. 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.
