| Abstract: | Objective To prepare quality control samples with uniformity and stability those meet the requirements for proficiency testing, and verify the ability of the quality control samples for the total number of colonies. Methods The test samples were composed of 2 samples with high concentration (3×104 CFU) and low concentration (1×104 CFU). Randomly selected samples were tested the stability and uniformity. This design distributed samples by randomly grouping laboratories to prevent collusion in laboratories in proficiency testing activities. Results Totally 65 laboratories participated in this proficiency test, 80% of the laboratories with excellent results. This proficiency test could truly reflect the detection level of the participating units. Conclusion This verification samples of total number of colony can be used for quality control samples. |
