Range age of the study groups was (20-40) years. In the control group: serum T3 andT4 levels were decreased slightly with increasing age respectively, while TSH levels were increased slightly with increasing age without significant difference P>0.05 and the values were within the normal range. In the hyperthyroidism which included (45) patients women , there were continuously higher in concentration levels of T3, and T4 than that in the control group, but TSH concentration decreased with highly a significant difference P<0.01.While, in hypothyroidism which included (45) patient women ,the concentrations of T3 and T4 were lower than that in the control group, but TSH increased with a highly significant difference P<0.05.
