Eurofins Excels in Shrimp Matrix Testing - Achieving Satisfactory Z-Scores in inter laboratory comparison testing.
At Eurofins, we take immense pride in delivering accurate and reliable food and feed testing services that meet and exceed global standards. Today, we are thrilled to share our latest achievement — a Satisfactory Z-Score in the inter laboratory comparison testing (ILC) round for Shrimp Matrix, conducted by The Marine Products Export Development Authority (MPEDA). This accomplishment underscores our commitment to quality, accuracy, and the highest levels of scientific integrity.
Understanding inter laboratory comparison testing (ILC): Why It Matters
Inter laboratory comparison testing is a critical quality assurance tool used by laboratories worldwide. It involves analyzing a specific sample (in this case, shrimp matrix) and comparing the laboratory's results against assigned values from a nodal testing authority. The main objective is to ensure that the participating laboratory consistently produces accurate and reproducible results under standardized conditions.
The performance of a laboratory in ILC is often evaluated using the Z-Score, a statistical measure that indicates the level of deviation from the assigned value. A Z-Score within the acceptable range demonstrates the laboratory's ability to produce valid and reliable results, reinforcing customer confidence in its testing capabilities.
Eurofins’ Performance in the Shrimp Matrix ILC Round
The ILC round was conducted by MPEDA under their programme MPEDA/BHM/ILC-01/2023. Eurofins participated in this round, which required testing specific parameters in shrimp matrix samples, including pesticides and polychlorinated biphenyls (PCBs). Our performance across all parameters resulted in satisfactory Z-Scores, which are summarized below:

Interpretation of Results
- Z-Score of 0.00 (HCB): Perfect alignment with the assigned value, indicating impeccable accuracy.
- Z-Score within ±0.5 (DDT & PCB-52): Satisfactory results, demonstrating strong analytical capabilities.
- Z-Score of -0.47 (PCB-153): Still within acceptable limits, validating our testing precision.
Each of these results demonstrates the reliability of Eurofins’ testing protocols, methodologies, and analytical expertise.
