Unique identifiers can be created using various methods, ranging from simple numerical codes to sophisticated barcode systems. The choice of method often depends on the laboratory's requirements and the complexity of the study. Some common techniques include:
Numeric or Alphanumeric Codes: These are straightforward and can be easily generated using software or manually assigned. Barcodes: Barcodes provide a quick and error-free way to identify specimens. They can be scanned, reducing the time needed for manual data entry. QR Codes: These are similar to barcodes but can store more information, including links to digital records or databases. RFID Tags: Radio-frequency identification (RFID) tags are used for more advanced applications, where remote scanning of specimens is required.
