Abstract:
The purpose of this study was to determine whether the fully automated ORTHO AutoVue Innova system, which based on the microcolumn glass sphere technology, is accurate enough to meet immunohematology testing needs at blood banks. 16 IgM anti-C, anti-c, anti-D, anti-E and anti-e dilution series were tested respectively, with corresponding antigen positive red blood cell solutions, by ORTHO AutoVue Innova system and saline medium test. 16 IgG anti-D dilution series were tested respectively with RhD positive red blood cell solutions by ORTHO AutoVue Innova system, polybrene test and antiglobulin test. The accuracies of microcolumn glass sphere technology were analysed, by comparing to the reference assays. The results showed that the sensitivities of the ORTHO AutoVue Innova tests were 1:69.8, 1:33.4, 1:1448.1, 1:139.6 and 1:32.0 for IgM anti-C, anti-c, anti-D, anti-E and anti-e respectively; the corresponding value of saline medium tests were 1:16.7, 1:16.6, 1:430.5, 1:34.9 and 1:9.9. There were statistically significant differences between the groups of each tests (t values were 14.38, 5.48, 10.25, 12.65 and 9.59 for IgM anti-C, anti-c, anti-D, anti-E and anti-e respectively, p < 0.05). For IgG anti-D, the sensitivities of the ORTHO AutoVue Innova test, polybrene test and antiglobulin test were 1:980.6, 1:181.0 and 1:304.4 respectively. There was statistically significant difference among the 3 groups (F = 51.15, p < 0.01). It is concluded the use of ORTHO AutoVue Innova system for blood group compatibility test can obtain more accurate results than traditional tube tests, it is reliable and safe for routine tests performed in immunohematology laboratories.
