External Evaluation of the Quality of the Seven Biochemical Parameters in Antananarivo in 2020

The aim of the present study is to assess the performance of the biochemistry laboratory of Joseph Ravoahangy Andrianavalona by the dosage of the most prescribed 7 biochemical parameters. It is a retrospective evaluative study of the performance of the biochemistry laboratory of Joseph Ravoahangy Andrianavalona University Hospital Center on a period of 6 months from January 2020 to June 2020 involving 12 samples of External Evaluation of the Quality provided by the Quality Insurance Association of the clinical Biology Laboratories in France. Uremia, Serum creatinine, blood glucose, natremia, kaliemia, chlorure and were dosed on the 12 samples which carried out 84 dosages. During a period of 6 months the accuracy was 97.61%. The precision had been 100% if the Variation Coefficient Ratio (VCR) was below 1.50. This participation in the External Evaluation of the Quality program can then improve the quality of the laboratory. It is a step towards the accreditation process.
