Зачастую по результатам гормонального исследования можно сделать вывод о наличии манифестного (субклинического) гипотиреоза или манифестного (субклинического) гипертиреоза. В такой ситуации трудностей в постановке диагноза и назначении лечения пациенту обычно не возникает. Однако в клинической практике можно столкнуться с ситуацией, когда результаты лабораторных исследований не соответствуют клинической картине и/или нормальному функционированию гипофизарно-тиреоидной оси по принципу логарифмической отрицательной обратной связи. В таких ситуациях достаточно часто неадекватные результаты можно объяснить лабораторными погрешностями, влиянием лекарственных препаратов или наличием генетического заболевания. Также в последнее время все больше вопросов возникает при диагностике синдрома эутиреоидной патологии. Правильный алгоритм действия в данных ситуациях будет играть ключевую роль в постановке диагноза и определении дальнейшей тактики ведения пациента. В данной работе будут рассмотрены факторы, приводящие к изменению лабораторных показателей, и структурированный подход к исследованию функционального состояния щитовидной железы, что имеет большое значение в клинической практике.</p></abstract><trans-abstract xml:lang="en"><p>In most cases, estimation of tests of the functional state of the thyroid gland does not cause difficulties. Often, according to results of hormonal research, we can conclude that there is a manifest (subclinical) hypothyroidism or a manifest (subclinical) hyperthyroidism. In these situations, difficulties in diagnosing and prescribing treatment to the patient usually do not arise. However, in clinical practice, can be a situation when the results of laboratory researches either do not correspond to clinical picture or do not correspond to the normal functioning of the pituitary-thyroid axis by the principle of log negative relationship. In such situations, quite often inadequate results can be explained by laboratory errors, effect of drugs or existence of genetic disease. Also, recently more and more questions arise in the diagnosis of the syndrome of euthyroid pathology. The correct algorithm of action in this situation will play a key role in diagnosing and identification of further tactics of patient management. In this study will be considered factors that lead to changes in laboratory researches and structured approach to assess functional state of the thyroid gland, which has big importance in clinical practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>щитовидная железа</kwd><kwd>тиреотропный гормон</kwd><kwd>синдром резистентности к тиреоидным гормонам</kwd><kwd>тесты функционального состояния щитовидной железы</kwd><kwd>тиреотропинома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thyroid gland</kwd><kwd>thyrotropin</kwd><kwd>thyroid hormone resistance syndrome</kwd><kwd>thyroid function tests</kwd><kwd>thyrotropinoma</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">donlab.ru [интернет].
