The United States Preventive Services Task Force — the only believable resource for guidance on screenings — says screening for thyroid disease lacks a scientific basis. Specifically, they said: “The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for thyroid dysfunction in nonpregnant, asymptomatic adults. (I statement)” In other words, no one has studied this sufficiently to know whether it’s a good idea or not. The lack of evidence is not carte blanche to go ahead and do it anyway, but that’s never stopped wellness vendors before. The lack of evidence means to pause and take a deep breath before telling people to do “just in case.” You buckle your seatbelt “just in case,” you don’t submit to metabolic testing for the same reason.
How long do you suppose it will take the wellness industry to get this message? We’re betting three years or more.
