iodine loading test/reliability of skin test for iodine sufficiency

http://www.breastcancerchoices.org/loading.html
Dr. Guy Abraham and his colleagues have found the 24 Hour Iodine Loading test helpful in gauging a patient's iodine sufficiency. The principle is, if the body's level of iodine is adequate, most of the iodine ingested during the test will be excreted in the urine. If the body is deficient in iodine, a significant portion will be retained by the body.

Is the application of iodine to the skin an acceptable way to supplement iodine?
Many 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. In order to regenerate iodine on the skin, one needs to apply an oxidant such as hydrogen peroxide, complicating the test further. The evaporation of iodine from the skin increases with increased ambient temperatures and decreased atmospheric pressure due to weather conditions and altitude. For example, the yellow color of iodine will disappear much faster in Denver, Colorado at 5,000 feet above sea level then Los Angeles, California at sea level, irrespective of the amount of bioavailable iodine. The iodine/iodide loading test (4) is much more accurate and it is now available from two laboratories: Tweet
