Tóm tắt

An essential part of medical laboratory quality assurance is statistical quality control (SQC) which requires the laboratory to analyse quality control materials. Our research focused on lyophilized quality control material that can be produced using materials from laboratory. Plasma samples, anticoagulated by heparin, that had common clinical chemistry parameters including creatinine, total cholesterol and AST, were collected from the Department of Medical Laboratory  at the Hanoi Medical University Hospital. All parameters were within the normal reportable range. The samples were lyophilized and tested for homogeneity and stability. Homogeneity and stability testing results for lyophilized and frozen control samples for creatinine, total cholesterol and AST showed no significant difference in 20 days across six assessment time points (p > 0.05). The results also indicated that despite the acceptable stability performance within 20 days. The procedure for production of lyophilized quality control material for several clinical chemistry tests showed initial success.
