Abstract

Background : Internal Quality Improvement (PMI) is a preventive and monitoring activity carried out by each laboratory continuously to prevent or reduce the occurrence of errors/deviations so that correct inspection results are obtained. Quality Control on the Hematology Analyzer tool is important to carry out an analysis of accuracy, precision, and then evaluated using the Levey-Jennings chart which aims to determine any measurement deviations in the tool QC Level-N, QC Level-L, QC Level-H should be stored at 2-8°C before and after opening. If treated like this, unopened products are guaranteed to be stable until the expiry date stated on the packaging. Once opened, the product is stable for 7 days if returned immediately to the refrigator after use. Research purposes is knowing the differences in material quality control inspection results on the hematology analyzer before and after going through the open stability period.

Methods: This research uses a descriptive observational study with a cross sectional design. This research was carried out in November-December 2024.

Result: The average results of the material quality control examination on the hematology analyzer before going through the open stability period were at low level WBC 3.47, RBC 2.64, HGB 6.2, HCT 18.07, and PLT 93.29, at a normal WBC level 7.06. RBC 4.40, HGB 11.87, HCT 33.24, PLT 219.71, at high level WBC 17.24, RBC 5.29, HGB 15.91, HCT 43.87, PLT 522.14. The average results of the material quality control examination on the hematology analyzer after passing through the open stability period were at low levels WBC 3.54, RBC 2.64, HGB 6.2, HCT 18.21, and PLT 91.29, at normal levels WBC 7.13, RBC 4.42, HGB 11.89, HCT 33.54, PLT 221.57, at high WBC level 17.26, RBC 5.30, HGB 15.96, HCT 44.07, PLT 524.71.

Conclusion: There was no difference in the results of material quality control checks on the hematology analyzer before and after going through the open stability period.
