An iodine test on the skin is performed by painting a patch of iodine solution on the skin, such as the inner arm, and observing how quickly it disappears to estimate iodine levels. If the patch disappears within a few hours, it may indicate an iodine deficiency, while a patch that takes longer to disappear suggests adequate iodine levels. *Not medical advice #iodine #health #thyroid #thyroidcancerawareness #hashimotos #wellness #healing #diy #remedy #naturalremedies #holistichealth #didyouknow
