Basal Temperature Test (Thyroid Testing)
Take your temperature using a thermometer under your arm first thing in the morning. Thermometers that scan the forehead or body are not accurate enough. Record your temperature for 5 days in a row. An under-functioning thyroid will show as less than 97.6º F.
An iodine patch test is supposed to measure the absorption rate of iodine by your body which will theoretically let you know if you are deficient or otherwise.
- Paint a 3-inch by 3-inch square on your abdomen, inner thigh or inner forearm.
- Allow it to dry before touching anything, as it will stain.
- Monitor the patch over the next 24 hours for color changes.
Your iodine test should last up to 18–24 hours.
