Traceability 29 is demanded by Schüll and Gerhold [48] as a general feature of good academic practice that should be required in futures research, too.
Some other physicochemical methods have high sensitivity, accuracy and clear metrology traceability [11], however they are still often hampered by the efficiency of the phosphodiesterase enzyme digestion.

Sugiura et al. achieved the marking of livestock information through special ear tags, which enabled the rapid acquisition of livestock information, which laid the foundation for realizing individual animal traceability [12].
The entire operation is simplified, from obtaining the image to the cycle time involved in obtaining, evaluating and storing each image with ensured traceability [4], as illustrated in Figure 2. Figure 1 Pipeline in deep water.
Several studies have applied the 2D barcode in food traceability 70, 73, 74, 75.
One of the background articles in this journal supplement provides information on key concepts and guidelines for clinical laboratory testing and how working laboratories that commonly use commercial assay kits or in-house measurement procedures can achieve traceability (5).
Furthermore, the concept of metrological traceability (15), which is essential to ensure comparability and accuracy of measurement results, is not yet established in cell counting because of a lack of reference material and reference measurement procedures.
The introduction of mandatory horse passports in 2005 was viewed as an opportunity to improve horse traceability [ 1, 2].
The technical requirements include topics such as method validation (Section 5.4), measurement traceability (Section 5.6), and reporting the results (Section 5.10).
