#SEROscience: Decoding Troponin I & CA 15-3 Biomarkers

Harmonization and standardization of laboratory measurement techniques aim for equivalent measurement results to correctly interpret test results and give the correct medical advice independent of time and place of analysis. However, harmonization of immunoassay measurement techniques is largely lacking since internationally recognized reference materials and measurement procedures are missing, also because the measureand itself is often poorly defined.

Here, we assess the comparability and reproducibility of measurement results using different sources of the breast cancer marker CA 15-3 (Figure 1) and the cardiac marker Troponin I (Figure 2) on commercially available immunoassay platforms.
