Learnings from five years of External Quality Assessment (EQA) for porphyrias

The aim of the POR EQA is to assess the entire genetic diagnostic pipeline of a laboratory, including sample receipt and processing, genotyping,
and reporting (biological and clinical interpretation of the test result) in the context of mock clinical referrals as well as reporting clarity, content
and clerical accuracy. Through assessment and feedback in individual laboratory reports and summary scheme reports, laboratories are able to
improve their practices.
