Abstract
Thyroid dysfunction (hypothyroidism and hyperthyroidism), has been linked to dyslipidaemia with significant variations in the numbers of those suffering from these conditions in populations around the world. This present study examines 46 patients in Nofliyeen diagnostic laboratory in Tripoli, Libya with these conditions, and compares their TC and TSH levels with 58 healthy controls. 5 ml of venous blood was drawn from each participant and TC was measured using spectrometry method by Evolu-tion 3000. The COBAS e 411 (Roche, Germany) electrochemiluminescence technique was used to measure TSH. A positive correlation was found between TC and TSH in patients with hypothyroidism and a negative correlation observed between TC and TSH in patients with hyperthyroidism. TC levels were significantly higher in patients with thyroid dysfunction compared to the healthy control group.
