Abstract:
The External Evaluation of the Quality is an important procedure for assessing the performance of a laboratory. The aim of the present study is to assess the performance of the the biochemistry laboratory of Joseph Ravoahangy Andrianavalona by the dosage of the most prescribed 4 emergency 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 4 months from January 2019 to April 2019 involving 8 samples of External Evaluation of the Quality provided by the Quality Insurance Association of the clinical Biology Laboratories in France. Serum creatinine, blood glucose, uremia and serum electrolytes were dosed on the 8 samples which carried out 32 dosages. During a period of 4 months the accuracy was 94% for the 32 carried out dosages. The precision had been 97% if the Variation Coefficient Ratio (VCR) was below 1.50. The monthly assessment of the 3 studied parameters: serum creatinine, blood glucose and uremia were always good during the 4 months. The imprecision (VCR >1.50) concerned the disease control of the sodium levels in February. The University Hospital Center Joseph Ravoahangy Andrianavalona Biochemistry laboratory was efficient during the External Evaluation of the Quality. Therefore, these results were reliable and contribute to the improvement of the diagnosis, the monitoring and the aftercare of the patients. Every laboratory for medical analysis ought to organize a periodical External Evaluation of the Quality to monitor and improve biological analysis results.
