MIAO Renhua, ZHUANG Xingxing, ZHANG Peng. Establishment of Internal Quality Control Method for Blood Concentration of Theophylline. [J]. 21(4):441-443(2021)
OBJECTIVE: To establish an internal quality control method for the blood concentration of theophylline by enzyme-linked immunosorbent assay( ELISA) using Westgard multiple rules theory. METHODS: 5. 0 μg/ml
10. 0 μg/ml and 20. 0 μg/ml of quality control serum of theophylline were prepared
after 20 consecutive working days of monitoring on low
medium and high concentration of quality control serum
Levey-Jennings quality control charts and Z-score quality control charts were plotted
and Westgard multiple rule was used for its quality assessment.RESULTS: The precision
stability and recovery test results of the low
medium and high concentration of quality control serum of theophylline were all in accordance with the requirements; both the Levey-Jennings method and Westgard multiple rule control method suggested no uncontrolled situations. CONCLUSIONS: Using the internal quality control assessment system to conduct evaluation on blood concentration monitoring data of theophylline can ensure the accuracy and reliability of blood concentration determination
thus providing accurate information for clinical rational drug administration.
