Do hyperthyroidism tests require fasting?

Hyperthyroidism test is generally recommended fasting. For

example, liver function test, which is one of the most common tests for hyperthyroidism patients, fasting can ensure the accuracy of test results. If the test is performed after eating, some components in the blood may change, interfering with the judgment of liver function indicators. Moreover, although thyroid function test such as thyroid hormone level usually does not require strict fasting, fasting can reduce the potential interference of other factors, making the results more reliable.

In addition, fasting can exclude the influence of food digestion and absorption process on blood components and metabolism, so that doctors can focus more on the analysis and diagnosis of hyperthyroidism itself. In

order to obtain more accurate and reliable test results, it is recommended that patients keep fasting state as far as possible during hyperthyroidism test. However, if the patient cannot fast due to special circumstances, the doctor should inform the doctor in advance so that the doctor can comprehensively evaluate the accuracy and reference value of test results.
