Abstract: An adapter for test tubes is provided enabling attachment of information with identifying patient and/or test data, and which further facilitates insertion of test tubes into automated test equipment. The adapter has a cylindrical housing with two open ends into which a test tube and its attached stopper are received. In one embodiment, one end of the adapter is attached to the stopper and extends partially along the length of the test tube. In another embodiment, the adapter receives the entire test tube in a first position, and in a second position, the test tube and attached stopper are slid within the adapter housing, such that the test tube exits the housing and retains the stopper in the housing. When the assembly of the adapter and test tube is inserted into automatic test equipment, the adapter prevents the information attached to its housing associated with the sample from interfering with analysis of the sample contained in the test tube.
