How to Track the Iodine Patch Results
The iodine patch test needs a 24 hour window of time.
The iodine patch test measures how quickly your body absorbs iodine. The faster it absorbs it, the more likely you may need iodine. If the patch still exists 24 hours later as a pale shadow, the results are normal. If the patch disappears or mostly disappears in less than 24 hours, it may indicate some degree of deficiency. In fact, significant lightening or disappearance in under 8 hours could indicate moderate to severe iodine deficiency and suggest a need for supplemental iodine.
A few important notes about the iodine patch test… Make sure you use an iodine solution of the strength you are advised to take. It’s also important to remember that this is a home test and the results do not guarantee deficiency or adequacy of iodine levels.
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.
Iodine has many important functions in your body:
1.Stabilising of metabolism and body weight
2.Brain development in children
4.Optimization of your immune system (iodine is a potent anti-bacterial, anti-parasitic, anti-viral and anti- cancer agent).
5.Manufacture of thyroid hormones.
6.Endocrine feed back loop
7.Thyroid function= energy
9.Tendon flexibility and sensitivity
Perform test AFTER your morning shower. Do not apply skin lotions or shower gels to the test area.
Put one drop of lugols iodine on your inner arm, spread it into a patch about 3cm across. Monitor on an hourly basis. Record how long it took to be absorbed into your skin.
Note how long the test patch takes to fade away 1, 2, 3,4 hours etc.
A minimum shadow should be 8 hours, a very good reading should last 20 hours.
For some the test does not work. This may be because they have such a high burden of halides (fluoride, chloride, bromide) that all receptor sites are blocked. This can cause a false positive both on the patch test and urinary excretion tests. Try eating sea vegetables for two weeks then re do the test.
