The concentration of TSH receptor autoantibodies (TRAB) was determined by a radioreceptor assay kit (RRA) in serum collected from 30 normal adults (15 males and 15 females). The results showed that the overall mean level of TRAB is 1.360.57u/l. The mean level is 1.49+/-0.67u/l in men and is 1.22+/-0.44u/l in women. There was not significant difference between man and women in TRAB level.
