| Anmerkungen | The programme provides an assessment of the analytical performance of first-line laboratories undertaking both qualitative and quantitative analysis of PBG and TUP for the investigation of an acute attack and for laboratories offering an expanded repertoire for the investigation of cutaneous porphyria which also includes EDTA plasma and faecal porphyrin. Six urine samples are distributed every 3 months, 3 each for PBG and TUP along with 3 EDTA plasma samples for plasma porphyrin. Interpretative cases are distributed twice a year with Faecal porphyrin samples dispatched annually. For this programme participants are allowed 3 weeks to return their results. Reference target value assignment, EDTA plasma patient samples, faecal samples and clinical case interpretation are kindly provided by the Cardiff Porphyria Service. The Programme assesses both laboratory and method performance, including bias and within batch imprecision. The programme also assesses the laboratory’s pre and post analytical phases through the distribution of challenging samples (too dilute or concentrated) and the interpretation of Clinical cases. Key Features: - Covers both Qualitative and Quantitative assays. - Educational exercises including interpretive comments. - Reference target value assignment, EDTA plasma patient samples, faecal samples and clinical case interpretation are provided by the Cardiff Porphyria Service. - Challenging samples at or near diagnostic cut points.
