Abstract

The Asian Network for Clinical Laboratory Standardization (ANCLS) decided to start her First Inter-laboratory Quality Assurance survey at the business meeting during the Second Asian Colloquium on October 21-22, 2000 in Kobe, Japan. The first survey materials of Asian Quality Assurance Survey (AQuAS) were distributed in July 2001 to 21 hospitals in the field of chemistry and 22 hospitals in the field of hematology among total 24 participating laboratories from seven Asian countries: Indonesia, Japan, Korea, Malaysia, Philippines, Singapore and Thailand. The survey methods in chemistry and in hematology were somewhat different. In chemistry the survey material was considered as unknown but handled similarly to the sample from the patient. Nineteen routine tests were performed only once. The hematology samples were considered as unknown but handled similarly to control or calibration material. Five parameters were tested five times repetitively and their average for each parameter was calculated. All the results were supposed to be sent back to the office within two weeks. Although it took more than two weeks, the return rate was 100%. The analysis was performed in several ways such as all the results together, by instruments and by methods. Mean, standard deviation (SD), standard deviation index (SDI), coefficient of variation (CV) and variance index score (VIS) were to be calculated in chemistry, and in hematology the same parameter were to be calculated except CV and VIS. In the first survey, the CV in chemistry was not calculated and the analysis by instrument or by methodology was also not attempted since there were not enough participating hospitals to do such analysis. In hematology the analysis was done by instrument only. The survey process was carried out successfully though there were some difficulties in communication tools, transportation methods and handling of specimens due to different weather conditions, and returning the report in the correct unit and to the correct place. The submitted data were acceptable for analysis. There were some differences in the units of measurement in different countries or laboratories. It was necessary to convert some of the units. Some laboratories apparently do not perform certain tests such as calcium, potasium and γ-glutamyltransferase (γ-GT) The γ GT is the most frequently not performed test. With the experience of this first survey, all the members involved in the survey have been trained well to do future surveys.
