Barcodes have been a long-standing auto identification and data capture technology in the clinical chemistry market, routinely used on test tubes, cartridges, vials, pipettes, and cuvettes. In typical diagnostic applications, tracking the patient specimen is critical. Barcode identification has been used to ensure that a unique identifier associates the specimen with each of the diagnostic processing steps, resulting in a secure sample chain of custody. The process typically includes automated steps and system redundancy to ensure patient safety and accurate diagnosis.
In today’s rapidly changing medical testing environment, laboratory processes are becoming more efficient through the use of sophisticated diagnostic instruments, increased automation, and other commercially available technology. Over the past ten years, Radio Frequency Identification (RFID) technology has become widely available, and today it is routinely used in a variety of diagnostic applications.
