A T4 level of greater than 75 mcg/dL warrants close follow-up such as daily assessment for signs and symptoms of thyroid hormone excess.Symptoms are usually mild and consist of adrenergic excess: tachycardia, hypertension, fever.Treatment is symptomatic and may include beta-blocking agents and antipyretics.
