Stability of different biochemical parameters in pooled left-over sera stored for 14 days after pooling either at room temperature or at 2–10 °C

The majority of analytes in pooled leftover sera demonstrated acceptable stability, particularly under refrigerated conditions. Storage effects occurred consistently across pools, supporting reproducibility. These findings indicate that pooled sera from diagnostic leftovers represent a practical resource for EQA when analysed within defined timeframes.
