Thyroid Stimulating Hormone (TSH) 5.46 µIU/mL is generally normal, and the range of reference values may vary slightly from hospital to hospital. The normal value of serum thyroid stimulating hormone (TSH) ranges from 0.35 to 5.5 µIU/mL, and the range of reference values may vary slightly from hospital to hospital. 5.46 µIU/mL is generally normal and not a cause for concern. TSH abnormalities can be seen in hyperthyroidism, hypothyroidism, pituitary disease and other diseases. If necessary, thyroid hormone levels, thyroid autoantibodies (TPOAb, TRAb, TgAb), neck ultrasound and other related tests can be performed to rule out diseases. The specific interpretation of thyroid stimulating hormone also needs to refer to the patient’s condition and requires consultation with a doctor.
