In order to meet the requirements of conformance to the ISO/IEC 17025:2005 standard, D. S. Bioanalytics, participates in an international inter-laboratory Proficiency Testing (PT) schedule along with an intra-laboratory PT on site.

Normalized error is a statistical evaluation used to compare proficiency testing results where the uncertainty in the measurement results is included. Typically, it is the first evaluation used to determine conformance or non-conformance in proficiency testing.

We hereby present the data found for intra-laboratory comparison and proficiency testing over the period of January-August 2017
