Dr. Barnes' Basal Temperature Test (BBTT) is a method used to assess thyroid function. It involves measuring the body's basal temperature upon waking. The test is based on the idea that low thyroid function can result in a lower body temperature. According to Dr. Broda Otto Barnes, who developed and promoted the test, a normal reading upon waking is around 97.8 °F (36.6 °C). If the basal temperature consistently deviates from this range, it might indicate an underactive thyroid.
The BBTT is performed by placing a thermometer in the armpit for 10 minutes immediately upon waking. While this test can provide indications of thyroid issues, it's not a definitive diagnostic tool and should be used alongside other assessments. If the test suggests thyroid dysfunction, consult a medical professional for further evaluation and treatment options.
