What is a Thyroid Blood Test?

Both hyperthyroidism and hypothyroidism — too much thyroid activity and too little thyroid activity, respectively — are cause for concern. Because your thyroid controls much of your metabolism, which plays a vital role in your overall health, it’s important to monitor thyroid function, as it is estimated that up to twelve percent of the population in the United States will develop thyroid disease during their lifetime. That’s almost fifteen million people who have thyroid problems that affect their metabolism and are unaware.
