What is Internal Quality Control?
Internal quality control (IQC) involves analysis of control material of known concentration within predefined limits. This ensures the quality of the results produced prior to reporting any patient results from the POCT device
What is External Quality Assurance?
External Quality Assurance (EQA) involves analysis of a sample of unknown value from an external, independent source. The results are scrutinised by the EQA scheme provider and allow comparison of results across multiple sites. Participation in EQA allows monitoring of performance and possible early detection of a systematic problem with analysis of patient samples.
Any site wishing to introduce a new POCT service must enrol in a recognised EQA scheme.
Audit
The POCT team will perform audit of the service and provide feedback to the service lead. The audit outcomes and any corrective and preventative action are documented in the laboratory quality management system.
