Abstract: At present，there is no effective drug and vaccine to control the avian leukosis，so it is very important to detect and eliminate the positive individuals to purify the breeding flocks in a short time. Therefore，it is significant to select antigen detection kits with strong specificity，high sensitivity and good stability. Due to the impact of the epidemic novel coronavirus，some foreign antigen test kits can not be imported into China，it is necessary to find domestically?made kits with great sensitivity and stability. Therefore，in order to guarantee the continuous purification work，it is necessary to look for the domestic kits with great sensitivity and stability that is closest to the imported kit. The results showed that the sensitivity and stability of the different kits for the detection of the cell supernatant were different，the positive detection rate of the four kits was B>D>C=A. Among the four Avian Leukosis antigen test kits， the kit B had the highest detection sensitivity，the kit C had the best stability and closest to the imported kits. This study provides reference and data support for the kit selection in the process of Avian Leukosis purification.
