Quality assurance

To improve quality control, ensure best practice and gain ISO accreditation clinical laboratories must have an effective Quality Assurance (QA) programme.

The object of QA is to ensure that the right result is provided on the right specimen at the right time, and interpreted according to the right reference data.

This process requires a combination of Internal Quality Control (IQC) of the everyday analytical process and participation in External Quality Assessment (EQA) programmes, where overall accuracy and comparability of results between centres may be determined.

Quality assurance schemes are available for most analytical processes and the DLM participates in numerous schemes including External Quality Assessment from UK NEQAS which offers participation to the UK and overseas laboratories.

UK NEQAS schemes conform to high standards of professionalism, impartiality, clinical relevance and strict financial accountability across all disciplines and specialities, so that all concerned with the quality of laboratory investigations may have confidence in the service provided.
