Abstract：Objective To verify the testing capabilities of CT in 13 participating metrology institution laboratories through dose quantity measurement comparison in Jiangsu Province. Methods The 13 laboratories participating in the comparison used their own measurement standards to measure the same sample, and gave the measurement results and uncertainty evaluation reports. Results The maximum En value of the comparison results was 0.8, and the measurement results and uncertainty evaluation of each laboratory were within the reasonable expected range. Conclusion The testing capabilities of all 13 participating laboratories meet their standard and CT dose quantity in Jiangsu Province is accurate, reliable and uniform.
