How to Perform the Iodine Patch Test
Video Length: 2 minutes
What is the Iodine Patch Test?
The iodine patch test supposedly measures how quickly your body absorbs iodine. Again, this isn’t a proper substitute for a clinically-performed test that will actually measure your iodine levels accurately. Despite the popularity of the iodine patch test, no research supports its ability to measure iodine levels. That being said, here are the steps to perform it:
- Get a solution or tincture of iodine (the orange solution, not the clear one.
- 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.
Proponents of the test believe that the thing to pay attention to is how long it takes for the iodine patch to disappear. If the patch still exists 24 hours later, the results are normal. If the patch disappears or mostly disappears in less than 24 hours, it is supposed to indicate some degree of deficiency. In fact, significant lightening or disappearance in less than 18 hours is said to indicate moderate to severe iodine deficiency and suggest a need for supplemental iodine.
Is the Iodine Patch Test Actually Reliable?
Although several recent studies have demonstrated increases in iodine levels through skin absorption suggesting the result of this test may reflect a deficiency or adequacy of iodine, a lot of other factors suggest otherwise.

A number of factors play a role in the disappearance of the yellow color of iodine from the surface of the skin. For example, if iodine is reduced to iodide by the skin, the yellow color of iodine will disappear because iodide is white. The evaporation of iodine can also be affected by ambient temperatures and atmospheric pressure. If you’re looking for a way to test your iodine status, the loading test is much more accurate.
