Abstract

Pneumatic tube system (PTS) is a sample transport medium that is widely used in hospitals. Samples sent using PTS may be shaken due to the varying speed and air pressure in the PTS. The use of PTS can affect the examination of platelet counts and potassium levels. The installation of PTS at the Gadjah Mada University Academic Hospital was carried out in May 2020 in the Yudistira, Arjuna, Kresna and Nakula buildings. Delivery of laboratory samples at RSA UGM every day can be done from buildings with different distances. Every hospital that uses PTS is advised to validate PTS and investigate blood specimens for the possibility of hemolysis and laboratory results. The purpose of this study was to validate the PTS distance as a transport medium for laboratory examinations. This research is an experimental research which is a follow-up study using 30 samples. Samples were taken twice and sent with the PTS from two different distances, namely YD 2 and IGD. The statistical test will use a paired sample t-test. The data will be analyzed with the help of Prima Graph 8 Statistical Software with a significance level of 5%. The results of the analysis showed that there was no difference in the results of the examination of platelets and potassium sent from YD 2 or from the ER.

Abstract

The quality of laboratory test results is ensured by implementing quality control measures, which usually require control materials. The high cost of commercial control materials poses a challenge for laboratory quality control. Commonly, laboratory control materials are commercial control serums derived from animal serum that undergoes lyophilization during manufacturing. This study aims to assess the stability of CPDA pooled plasma that has been frozen for 60 days, using precision tests both within-run and between-day. Methods: This experimental research utilized CPDA pooled plasma samples from hematology laboratory waste at Poltekkes Kemenkes Semarang. The samples were frozen at -20℃ for 60 days. Quality control (QC) analysis was conducted using within-run and between-day precision tests without replication, to determine the standard deviation (SD) and coefficient of variation (CV). The results were then statistically analyzed using a one-way ANOVA to assess the difference in CPDA pooled plasma stability between the within-run and between-day precision tests. The QC results for within-day and between-day precision were as follows: the average for within-day was 4.066 and for between-day 3.2785; SD for within-day was 0.20 and for between-day 0.09; CV for within-day was 4.9% and for between-day 2.9%. The one-way ANOVA test showed a significance value of 0.316, indicating no significant difference between the within-day and between-day QC methods in terms of precision testing. Conclusion: CPDA pooled plasma remains stable in maintaining the precision of QC results for uric acid using the enzymatic colorimetric method (end-point) after 60-80 days of storage and can be used as an alternative to commercial control materials in uric acid QC testing.
