Quote – by Dr Jacob Teitelbaum – Testing for Thyroid Disease!
“Many years ago, while I was in medical school, physicians were taught to diagnose hypothyroidism, or low thyroid function, by using the newly discovered method of measuring the metabolic rate while the patient ran on a treadmill. Doctors thought this was a new test and that they finally had a way to identify patients with underactive thyroids. Doctors congratulated themselves on being so clever. But then a new test came out. The new test measured protein-bound iodide (PBI). When doctors began using the PBI test, they realized, `Oh, we missed diagnosing so many people with a low thyroid, but this new test will now pick up everybody who has a problem. The doctors patted themselves on the back and told all their newly discovered thyroid patients that it turned out that they were not crazy they just had a low thyroid. The doctors were comfortable that they could now determine with certainty when someone had a thyroid problem.
Then the T4-level thyroid test was developed and the doctors said, `Oh, that silly old PBI test. It missed so many people with a low thyroid, but this new test will find everyone. Then the T7-level test came out, and then the thyroid-stimulating hormone (TSH) test. Modern medicine is now into the fourth generation of TSH tests, and with each new test, doctors realized they missed many people with under active thyroids. You would think that we doctors would finally catch on. My impression, and the impression of many other physicians is that the current method of testing still misses many, many people with underactive thyroids. Therefore, doctors must treat the patient, not the blood test.
