title: [Quality control of capillary blood measurements in clinical services: follow up by the biologist].
abstract: In Bichat-Claude Bernard Hospital, the study of capillary glucose analyzers in the aim of uniformizing the selection of glucose meters, has shown the relevance of a standardized handling in order to obtain clinically interpretable results. It has been necessary to implement a quality follow up by the biologist. In the first stage, the biochemistry laboratory, with the clinical service supervisor and the supplier, has assured the training of the medical staff habilitated to use the meters and to carry out a quality control. In the second stage, the biologist implemented a monthly control on a total blood control sample, the stability of which has been checked after the necessary addition of glucose. Dosing of that sample, which is used as an external control, is carried out in parallel by the QID Precision glucose analyzer (Abbott) and by the portable Hemocue B Glucose (Vermed), which is selected as a comparison standard. This allows a monthly control of the accuracy of the meter. The condition of the equipment, as well as the weekly control follow up, validated by the nurse, is registered on a sheet prepared by the biologist. In partnership with Vermed, we have developed a processing software of the data stored in the Hemocue, allowing the automatic issue of a report summarizing the equipment condition and the data of weekly and monthly controls follow up. This report, signed by the biologist, is sent to every Service Manager and Supervising Nurse. On the basis of our one year experience, this practice has generated an efficient collaboration between the clinical services and the biochemistry laboratory, allowing to keep the quality of the capillary glucose measurements performed in inpatients.
