This study was designed to find the frequency of different abnormalities that can be observed in the results of thyroid function tests in patients with chronic renal failure, who are on hemodialysis, to assess the effect of having chronic renal failure on these frequencies, and to assess effect of age, duration of chronic renal failure, total serum protein level and serum albumin level of the results of thyroid function tests in patients with chronic renal failure, who are on hemodialysis. So that 35 patients with chronic renal failure and on hemodialysis had been randomly selected from those who attended the hemodialysis unit at Al-Yarmouk Teaching Hospital during the period from July 2016 to February 2017, Age and sex matched control had been selected randomly (35 patients). Detailed questionnaire had been applied containing information about the personal information and risk factors. 2 investigated for thyroid function tests and total serum protein and serum albumin levels. This study had shown there is general tendency of all thyroid function tests to be low but with the normal range, this tendency had been shown according to age, duration of chronic renal failure, level of serum albumin and total serum protein. Lower T3 levels are associated statistically with older age, and lower serum albumin levels. Lower TSH is associated with older age and higher total serum protein levels.

All of the patients investigated for thyroid function tests and total serum protein and serum albumin levels.
