If the results of thyroid hormone test are not the same in two days, it is recommended to do further detailed examination to clarify the cause of the disease and follow the doctor’s instructions for treatment. The normal value of thyroid stimulating hormone ranges from 0.35 to 5.5μIU/ml, and there are many reasons for the different results, such as diet, medication, hyperthyroidism, hypercortisolism, Hashimoto’s thyroiditis and so on. Therefore, for those who have different results of thyroid stimulating hormone in two days, it is recommended to do further detailed examination to clarify the cause of the disease. It is worth noting that thyroid stimulating hormone secretion has a circadian rhythm, generally the value is higher in the morning from 2 to 4 a.m. and lower in the afternoon, so it is recommended that the testing time should be consistent as much as possible. If the symptoms are caused by diet or medication, they can be improved by adjusting the diet and stopping the medication as prescribed by the doctor. If the test is caused by disease, it is necessary to follow the doctor’s advice to treat the cause of the disease so that the thyroid hormone can return to normal. It is recommended that people whose thyroid stimulating hormone test results are different in two days should actively cooperate with doctors for treatment, and should not indiscriminately use drugs or prescriptions on their own to prevent further abnormalities of thyroid stimulating hormone.
