Samples were collected in plain containers then centrifuged then the clear serum was separated and stored at 4 C⁰ until used, after that DNA was extracted by chloroform method and processed by conventional PCR using the following primers forward (5' – CCC TTG CGG ATG CCAAT -3' ) and reverse primer (5' – GGC TGA TAT GGA TGC CC - 3'). Out of 120 patients 34 (28 %) was positive for HBV DNA , 22(18.3%)were males, 98(81.7%)were females .Throughout the males population (22) only 6 samples was positive and 28 out of the females population (98) were positive .HBV DNA observed in 3 (2.5%) samples out of 40 cases and 31 (25.8%)samples from 40 suspected which was statistically significant, relying on the results hepatitis B virus its related to rheumatoid arthritis and arthritis symptoms pressed the onset of jaundice .
