RESUMO
A preliminary study was carried out to observe the levels of thyroid hormones among the normal elderly men and to observe the variation from the levels exhibited by men of younger age. The hormonal levels were measured using Abbott IMX system. Total T3, Total T4 and TSH were evaluated among 47 elderly men [mean age 53.23 +/- 1.00]. Data were analyzed using t-test. It was found that the normal levels of Total T3 and Total T4 did not vary significantly [p>0.05] from that of a younger group of men [28.6 +/- 0.02 years], however, TSH levels among the older men were significantly higher [p<0.001], although well within the permissible levels. It seems to indicate that a slight significant increase [p<0.001] in normal levels of TSH, and a non-significant decrease [p>0.05] in levels of T3 and T4, with age, takes place
