Diagnosis of Thiamin Deficiency
Physical examination Relief of symptoms when thiamin supplements are taken The diagnosis of thiamin deficiency is based on symptoms and the results of a physical examination, with emphasis on examination of the heart and nervous system. Tests to confirm the diagnosis are not readily available. Blood tests to measure electrolyte levels are usually done to exclude other possible causes. The diagnosis is confirmed if thiamin supplements relieve symptoms.
