In order to use the patch test, get some iodine tincture and just paint a stamp sized patch on the inside part of your wrist. Wait for 24 hours and if the brown stain fades, it is an indicator that your body is not getting the required amount of iodine for thyroid gland to perform its function normally.


In the event of you taking prescribed thyroid medicine, lack of iodine in the body will foil the body from correctly using it.
