Materials and Methods: descriptive observational study method was used, which included questionnaires and serologic tests. The questionnaires contained questions on personal specifications, according which as many as ۷۶ individuals were qualified as the subjects of the study. Blood samples were taken from the subjects in order to run test on Hepatitis B by using ELISA test. Statistical analysis was done on the obtained data by using Chi-square test and Fisher’s exact test. Results and Conclusions:: According to the obtained results, ۶.۶% of the students had a negative titer, while another ۶.۶% were in borderline situation; whereas ۸۶.۸% produced a positive titer. Furthermore, the results revealed that there was an insignificance difference between Hepatitis B Antibody titer values and variables such as gender and needlestick injuries (P≥۰/۰۵); whereas, Hepatitis B Antibody titer was significantly different for pre-clinical and clinical students.
