Abstract:
Objective To evaluate the consistency of testing results for various items in the compound allergen program by conducting external quality assessment scheme.Methods The feedback results of external quality assessment for the compound allergen program performed by Shanghai Center for Clinical Laboratory(SCCL)during 2022 and 2023,including house dust mite,dust mite,cat hair,mugwort,terraced grass,milk,hazelnut,and peanut,were collected and analyzed.Results The compound allergen program was conducted four times,with 104,107,124,and 122 participating laboratories,and the qualification rates were 99.04%,99.07%,99.19%,and 100%,respectively.The specified values of the house dust mite,dust mite,and mugwort items were the same in each group,and the consistency of the results for different reagent groups was relatively high.There was inconsistency in the specified values(negative or positive)of cat hair and milk items between different reagent groups.The consistency of the results among the other rea-gent groups was high,except for the reagent used for detecting compound targets by which the terraced grass,hazelnut,and peanut al-lergens could not be detected.Conclusion The number of participating laboratories in the compound allergen program is gradually in-creasing,and the external quality assessment results of the 8 items covered are good.The overall qualification rate is high,and the con-sistency of reagents from different manufacturers is good.
