Abstract:

BACKGROUND: Liquid chip techniques (Luminex) is a recently rising method for detecting anti-panel reactive antibody, which is characterized by high sensitivity, and strong specificity, less interference and high flux.

OBJECTIVE: To compare the sensitivity and detection difference of panel reactive antibody in serum of kidney disease patients detected by enzyme-linked immunosorbent assay and Luminex. 

METHODS: Serum samples of 280 patients with kidney disease were selected. The enzyme-linked immunosorbent assay and Luminex methods were used to measure positive rate of panel reactive antibody. Chi-square test for fourfold table data was utilized for statistical analysis.

RESULTS AND CONCLUSION: The positive rates of panel reactive antibody were respectively 18.9% and 33.6% as detected by enzyme-linked immunosorbent assay and Luminex method. The positive rates of anti-HLA-I antibody and anti-HLA-II antibody were respectively 12.8% and 12.5%, as detected by enzyme-linked immunosorbent assay. The positive rates of anti-HLA-I antibody and anti-HLA-II antibody were respectively 25.0% and 20.7%, as detected by Luminex method. Positive detection rate was significantly higher in the Luminex group than that in the enzyme-linked immunosorbent assay group. Moreover, Luminex method could precisely detect the low-concentration antibody. Chi-square test for fourfold table data showed P < 0.01. Significant differences in the differences of panel reactive antibody of kidney disease patients were detected between the two methods. Results demonstrated that compared with enzyme-linked immunosorbent assay, Luminex method is more sensitive and accurate, and more suitable for clinical detection.
