Preparation of external quality assessment materials for complete blood count
Main Article Content
Abstract
External quality assessment materials play an important role in external quality assessment. The research aims to prepare external quality assessment materials for the complete blood count. Three batches of samples (24 items/lot, V = 2mL) with different levels were prepared as simulated whole blood, containing the following components: human red blood cells fixed with Glutaraldehyde 0.015%, chicken red blood cells fixed with Glutaraldehyde 0.18% (to simulate human white blood cells), human platelet cells fixed with Glutaraldehyde 0.007% and human serum supplemented with antibiotics. The final products were evaluated for quality according to ISO 13528:2015 standards based on two criteria: homogeneity and stability. Obtained results showed that all final products meet the criteria for homogeneity on 11 parameters: RBC, HGB, HCT, MCV, MCH, MCHC, RDW%, WBC, PLT, MPV, PCT; stability achieved in transport condition (transportation distance > 600km, transport time < 72h) on 10 parameters: RBC, HGB, HCT, MCV, MCH, MCHC, WBC, PLT, MPV, PCT, stability achieved in storage condition at 2 - 8oC for up to 4 weeks on 6 parameters: RBC, WBC, PLT and HGB, MCH, PCT.
