Abstract:
【Objective】 To investigate whether the current retention methods in blood stations can fully meet the traceability requirements of blood test results by analyzing the traceability of retained samples for syphilis antibody testing. 【Methods】 Thirty-four one-assay-positive deep-well plate retention samples, 68 double-assay-positive deep-well plate retention samples and 263 negative retention blood braids and corresponding deep-well plate retention samples that expired retention period for syphilis antibody testing from 2014 to 2020 in our center were collected. The TP-ELISA assays of two manufacturers were used for retesting, and the results were recorded and compared with the original results statistically. 【Results】 The concordance rate of the double-assay-positive and single-assay-positive samples with their corresponding deep-well plate samples was 98.53%(67/68) and 67.65%(23/34), respectively(P<0.05). Specific results for single-assay-positive syphilis antibody samples and their corresponding deep-well plate retention samples were as follows: 1) Single positive (reagent A): 13 out of 14 original samples were 0.65
