MALABSORBTION VS PSEUDO-MALABSORPTION IN LEVOTHYROXINE ABSORPTION TEST

The most common causeforpersistent elevation of TSH levels in hypothyroid patients treated with levothyroxine is poor compliance. The Levothyroxine Absorption Test (LAT) is usually confirmed this phenomenon called “pseudo-malabsorption”.

Hypothyroidism is a condition of reduced production, distribution, or absence of action of thyroid hormones. Clinical diagnosis of hypothyroidism is not easily established due to the nonspecific clinical manifestations. Determination of serum TSH is the first-line test for the diagnosis of hypothyroidism. The aim of the study was to determine the presence of other endocrine disorders in patients with subclinical (TSH levels between 5 and 10 mIU/l), or clinical (TSH above 10 mIU/l) hypothyrodism. We analyzed 50 patients (35 with clinical hypothyroidism and 15 with subclinical form).
