Background: Generally, HBV infection serum markers have been globally measured, and the analysis of entire an-tibody details include the affinity, total protein content and antibody activity are rarely measured between two different ethnic groups. We detected and determined the entire characteristics of anti-HBs (antibody to HBs anti-gen) among Sudanese and Chinese HBV resolved patient’s using a terminal antibody (TA) method.
Method: Serum samples of Sudanese and Chinese resolved HBV infection positive anti-HBs were collected. All se-rum samples were diluted in serial dilutions (20, 40, 80, and 160 dilutions). Anti-HB markers were measured with enzyme-linked immunosorbent assay (ELISA), antibody affinity, total protein content, and total antibody activity to anti-HBs were calculated according to the results obtained for each dilution.
Results: The antibody affinity to HBV statistically showed higher significance among Sudanese than Chinese (p < 0.05). The total antibody activity to HBV among Sudanese was higher statistically than Chinese patients (p < 0.05). Statistically, there was a high correlation between age and antibody affinity to HBV among Sudanese compared to the Chinese group (p < 0.05).
Conclusions: The measurement of the antibody affinity, total antibody activity, and protein content of anti-HBs among Sudanese and Chinese, two different ethnic groups, may predict HBV infection status among African race and Asian race, and in addition, may play an important role in a high or a low incidence of the disease between different ethnicities.
