Abstract
Current algorithms for managing patients with iodine deficiency are presented in the article, including the optimal complex of laboratory evaluation of thyroid status before prescribing therapy — determination of TSH, free T4 (and free T3), ATPO (and ATTG), in case of suspected hyperthyroidism — determination of TSH receptor stimulating antibodies. In case of nodular goiter, determination of parathormone levels, calcium Ionized, 25-hydroxyvitamin D is recommended.
The necessity to take into account the interfering factors that influence the laboratory results (concomitant conditions in the patient, medication, adherence of the patient to the preanalytic stage), including the possibility of obtaining false results if the patient takes biotin and laboratory tests are biotin-dependent.
