The document summarizes a scheme for distributing monthly liquid samples for external quality assessment. It includes mainline chemistry analytes distributed in 3.5ml and 1ml aliquots. The material is human serum manufactured to high specifications and sterilized to maintain integrity and commutability. Reference target values are assigned for key analytes to assess traceability. Performance reports identify components of imprecision and inaccuracy, and provide group reporting in graphical and tabular form to manage performance across sites. The scheme also includes samples for assessing linearity, validating new equipment and methods, and challenging laboratories.

Please note: Violet = Reference method accredited to ISO 17025 & 15195 Mainline Chemistry EQA Scheme Material Off the clot Human serum manufactured to a high specification to maintain integrity and commutability of the base material. Filtered to 0.2袖m and gentamicin added to maintain sterility. NO PRESERVATIVES ARE ADDED. ISO 15189 Compliance- WEQAS can help! Linearity Linearly related serum samples covering the pathological range to assess your method linearity. Metrological Traceability EQA material with Reference Target values assigned for: Na, K, Li, Mg, Ca, AST, LDH, GGT, ALT, Creatinine, Glucose and UA. Equipment Validation/Method Verification panels A range of samples with full metrological traceability for validation of new equipment and methods available. Performance Management Reports EQA performance report identifies components of both imprecision and inaccuracy, with uncertainty of the target value provided. Group / Regional reporting Includes per distribution and long term managers summary reports in graphical and tabular form. Managing Multi-sites/Sections? Challenging EQA samples distributed to assess both analytical performance and current laboratory practice.
