ANALYSIS OF QUALITY INDICATORS IN THE PREANALYTICAL PHASE OF LABORATORY DIAGNOSTICS AT THE CLINICAL DIAGNOSTIC LABORATORY OF THE «NATIONAL RESEARCH ONCOLOGY CENTER», ASTANA, KAZAKHSTAN

Abstract

Background. The primary focus of the clinical diagnostic laboratory is to ensure the attainment of high-quality results for
patient laboratory analyses.
Aim: This study aims to evaluate the effectiveness of employing quality indicators during the preanalytical phase in the
"NROC LLP" laboratory through a comparative analysis of the first and second quarters of 2022. By examining this aspect,
valuable insights can be gained to enhance the overall efficiency and reliability of laboratory procedures.
Results. The preanalytical phase encompasses a complex set of processes and actions that occur from the moment
laboratory tests are prescribed to the initiation of analytical measurements (such as sample loading into analyzers, etc.). This
stage involves not only laboratory staff but also the entire medical personnel of the departments. By implementing quality
indicators during the preanalytical phase, the functioning of the procedural unit, blood sampling techniques, and proficiency
in handling documentation can be assessed. Additionally, this study shed light on the organization of work within the
laboratory during this stage. The research methods employed were derived from "Quality Indicators in Laboratory Medicine"
proposed by the IFCC Working Group under the guidance of M. Plebani, as well as the current regulations of the Ministry of
Health of the Republic of Kazakhstan.
Conclusions. Based on our research, quality indicators tend to improve when regular work is conducted with laboratory
staff and the average medical personnel of our Center. Quality performance during this stage enables accurate diagnosis
and facilitates appropriate patient treatment.
