الملخص EN

The occurrence of thyroid abnormality and its relationship to age and gender, were studied in a total of 6334 blood samples drawn from Jordanians suspected of thyroid disorders (2873 males and 3461 females).

The patients who were referred by outpatient clinics, lived in the Great Amman District (Central Jordan), and their age ranged from 40-69 years.

The mean serum free triiodothyronine (FT3) levels were 4.30 pmol / L for the males and 3.94 pmol / L for the female population.

Abnormal FT3 values were found in 9.03 % of the males and 8.38% of the females.

Serum free thyroxin (FT4) levels were 15.33 pmol / L for males, and 15.55 pmol / L'for females.

Abnormal FT4 values was reported in 10.99 % of the males andin.9.S3 %, of the females.

TSH level averaged 2.18 mlU / L and 2.34 mlU / L for males and females, respectively, with 27.14% males and 28.56% females reporting abnormality.The authors suggest that more studies are necessary, in order to assess the prevalence of thyroidal disorders in the general population in Jordan.
