Pitfalls of Thyroid Stimulating Hormone Measurement in Two Cases with Hypertriglyceridemia

Abstract

Thyroid function tests (TFTs) are among the most commonly requested tests by physicians. Since the diagnosis of thyroid dysfunction requires long term treatment correct diagnosis and decision to treatment is important for the patient. In most patients the assessment of TFTs is quite easy but in a small subgroup test results are inconsistent. In our two patients who have hypertriglyceridemia descrepancy between their Thyroid-Stimulating Hormone (TSH) levels and clinical status detected. TSH levels decreased after treatment for hypertriglyceridemia. In this report, we would like  to emphasize the impotance of TSH pitfalls and interferences.
