RESULTS
-
HBsAg positivity of blood donors
Eight hundred and sixty nine cases out of 11,197 blood donors were positive for HBsAg, which gives 7.76% in HBsAg positivity of blood donors (Table 1). -
HBsAg positivity in age
The HBsAg positivity of 16–20 year old age group had the highest frequency (9.05%), 21–25 year old age group 8.23 %, 26–30 year old age group 5.72 %, 31–35 year old age group 5.76%, 36–40 year old age group 5.85%, 41–45 year old age group 4.76%, and 46–50 year old age group 3.7%. HBsAg positivity had a decreasing tendency of frequency by increasing age age (Table 2). -
HBsAg positivity in sex
The HBsAg positivity of male was 8.36% and female 6.0%, males had a slightly higher positivity than females (Table 1). -
HBsAg positivity in occupation
HBsAg positivity of the merchant group had the highest frequency (10.26%), and the next, the unemployed, salary man, student, soldier, in order of frequency (Table 3). -
HBsAg positivity in blood type
Type A had the highest frequency in HBsAg positivity with 8.07%, type B 7.83%, type O 7.49% and type AB 7.26%. Consequently there was no significant difference between the blood groups (Table 4). -
HBsAg positivity in past history
The HBsAg positivity is 5.06% in past history of hepatitis with jaundice, 1.04% in hepatitis without jaundice, 2.42% in blood transfusion, 12.54% in the liver disease among family, 3.57% in the cases admitted due to other disease, 75.37% in nospecific past history (Table 5). -
Results from liver function tests in HBsAg positive blood donors.
In 869 cases the level of SGPT was elevated in 93 cases (10.7%), which showed the highest frequency, SGOT in 67 cases (7.71%), total serum bilirubin in 46 cases (5.29%) and either one of SGPT, SGOT, and total serum bilirubin were elevated in 165 cases (Table 6).
