xed serum samples for these 4 items were tested throughout the
study. The results of electronic quality control，liquid quality control and mixed serum samples were analyzed. Results
Each result of electronic quality control passed in 2 phases. The liquid quality control results were within control when
they were assessed adopting Westgard sigma rules in different phases. The coefficient of variation （CV）of the mixed
serum sample results for 4 items were all <1/3 allowable total error （TEa）. Conclusions When microfluidic chip
POCT is used to test K，Na，Cl and Glu，under the condition of stable determination personnel and environment，
the same batch of reagents，the use of daily electronic quality control with weekly liquid quality control can ensure the
quality of analysis.
