Impact of sanitizers on quality of Lipase and Triglyceride analytes in clinical laboratory

Abstract

Use of sanitizers in diagnostic centres causes derangement in quality control values of lipase and triglycerides (TG) analytes during COVID-19. Our study provides a practical insight into the type of sanitizers to be used in a laboratory. Performance Verifier (PV) and reagents (lipase and TG) were contaminated with sanitizer and 70% isopropyl alcohol. Groups formed were- PVNet (G1), PV with Sanitizer (G2), PV with 70% Alcohol (G3), Sanitizer contaminated reagent (G4). Controls PV-1 and PV-2 were run. ANOVA and Tukey’s test among groups and between groups were compared. Significant difference in mean PV-1and PV-2 values of TG [PV-1, PV-2 (<em>P </em><0.0001)] and lipase TG [PV-1 <em>P </em><0.0001) PV-2 <em>P </em><0.001] among all tested groups were observed. Between-group analysis showed significantly higher PV-1 and PV-2 values in sanitizer contaminated PV group (<em>P </em><0.001) compared to Neat PVs (<em>P </em><0.001), and PVs contaminated with 70% alcohol (<em>P </em><0.001). sanitizer contaminated PV-1 values were significantly higher when compared to Neat PV-1 (<em>P </em><0.001)for lipase. It is advised that isopropyl alcohol (70%) should be preferred over glycerol containing sanitizers to reduce pre-analytical errors for lipase and TG estimation.
