MỘT SỐ NGUYÊN NHÂN CHỦ YẾU DẪN ĐẾN SAI SỐ TRONG NGOẠI KIỂM TRA CHẤT LƯỢNG XÉT NGHIỆM TẠI VIỆT NAM

Abstract

External quality assessment schemes (EQAs) is a very important tool in quality control. It  is used to control test results, the external quality assessment results of each hospital reflect the majority of its quality in medical laboratory, which is one of the mandatory requirements of Ministry of Health [1],[2],[3],[4],[7]. This study analyzed the EQAs data from the medical laboratories in 2021, compared to the past period, so that we can evaluate if there are  improvements or not and find out the reasons that caused the errors. Results: The error area has been gradually narrowed through the implementation process, specifically, the Biochemistry, Hematology, Immunology, Clinical Microbiology, Urinalysis,…. The error is gradually approaching the target point (0%), particularly, PCR-HCV recorded a relatively high error in the current year (26.5%) compared to the first year of implementation (14.5%). Three major reasons causing the errors in EQAs are: (1) Unsuitable registering method, (2) Reagents don't meet the quality, (3) Range of the EQAs concentration.
