Redundant Identification for Sample Tracking on a Diagnostic Device

Abstract:

A sample-containing device configured to be placed into a sample processing instrument for performing a process on a sample contained in the device includes redundant identification features, such as machine-readable tags. A first machine-readable information tag is read before the device is placed in the instrument, and a second machine-readable information tag is read after the device is in the instrument. Information read from the two tags is compared to determine if there is proper correspondence between the information read from the tags to ensure that the correct sample processing device was placed in the instrument.
