The US Preventive Services Task Force (USPSTF) said that it cannot say with 100% assurance whether or not blood test should be done for thyroid dysfunction in adults without symptoms

The US government-backed panel said that more clinical trials and scientific evidence is needed to come up with a better solution. The USPSTF said, "The Task Force concludes that current evidence is insufficient to assess the balance of benefits and harms of screening for thyroid dysfunction in nonpregnant, asymptomatic adults".

The task force has warned about the potential risks involving screening of asymptomatic individuals. If by chance, false positive results report comes then it could result into potential physical harms from overtreatment.

It shall, however, be noted that these recommendations are absolutely not for people who have symptoms including weight gain, weight loss, palpitations, fatigue, or skin changes. People who are facing symptoms and laboratory-confirmed hypothyroidism, levothyroxine can be recommended by a medical provider to lessen the symptoms.

Thyroid is a gland in the neck that produces hormones that severely affect many body processes like metabolism and growth. If the condition is not treated then thyroid dysfunction can lead to disastrous results, including death or a number of conditions, like heart disease and cancer.

A blood test can reveal whether the person has thyroid problem. In the blood test, thyroid-stimulating hormone (TSH) will be checked. The hormone makes the thyroid to produce its own hormones.

The USPSTF suggested that abnormal tests should be confirmed with repeat testing over three to six months. As per a data, a quarter of US adults are screened for thyroid dysfunction annually. Experts suggested that it all depends on whether thyroid is over-reactive or underactive and on that basis, its treatment is based.
