The term “tsh” generally refers to thyroid stimulating hormone (TSH), and the normal range of thyroid stimulating hormone is 0.35 to 5.5 μIU/ml, so a value of 10 μIU/ml of thyroid stimulating hormone is elevated. Due to different examination methods and reagents, the reference indexes are different in each hospital and need to be analyzed specifically. Common causes of high thyrotropin include primary hypothyroidism, Hashimoto’s disease with hypothyroidism, exogenous thyrotropin-secreting tumors (e.g., lungs, mammary glands), and recovery from subacute thyroiditis. In addition, ingestion of lithium metal, potassium iodide, and thyrotropin-releasing hormone can increase thyrotropin. If an abnormally high value of thyroid stimulating hormone is detected, it is recommended to seek prompt medical attention under the guidance of a specialized physician.
