Performing Iodine Skin Test; At Brief

By Olive Pate


One of the major building blocks used by the thyroid in hormone production for use in metabolic processes is iodine. If it is not enough, several derangements happens hypothyroidism being one of them. Among the popular methods of testing for the deficiency is iodine skin test.

It theoretically measures how fast the iodin is absorbed into the body via the skin. It is not perfectly reliable because it does not give the levels of iodine concentration in the body as would a test carried out by the doctor. It just gives the speed of absorption. It cannot therefore used as a substitute to the usual laboratory tests.

It is done using a solution of iodine of tincture. The normal color of the solution is yellow. A three by three inch patch of skin is painted with the solution. The preferred sites are the abdomen, inner forearm or the inner thigh. It should be allowed to dry completely before you touch anything as staining can happen. The spot is observed for the following 24 hours for changes in the color.

What one should be keen about is the time taken for the spot to fade in color. If it is still present 24 hours after the painting, then the results are within the normal ranges but if disappearance takes place before 24 hours are over, then some deficiency is present. In addition, if significant lightening occurs within 18 hours, this is an indication of sever to moderate deficiency. Supplementation may have to be considered.

Several factors interact together to cause the color disappearance. Iodide is the component which results when iodin is reduced by the human skin. It is white and that is why the original color disappears. Evaporation is affected by the room temperatures and also the atmospheric pressure. Loading test is a better choice when reliability and validity of the results is desired.

Thyroid dysfunction may be the cause of low levels. Iodin is required by the gland for several purposes including maintaining of a positive attitude mentally, providing energy, keeping the menstrual cycles ordered, muscle growth enhancement, weight control, stabilizing cholesterol levels, regulation of heartbeats and hormone balancing.

About two thirds of the iodin found in the human body is kept in thyroid gland. Taking seaweed vegetables is a sure way of boosting the iodine content in the body. One spoon a day of this is enough to regain the normal levels. Seafood of even fish can also help out. Other food types containing iodin are eggs and also dairy products. Goitrogens are foods which hinder utilization of iodin in the body. They are food like cabbage, kale, soy flour, peanuts, cauliflower, Brussels sprouts, turnips and kohlrabi.

To revitalize the gland, selenium, copper, zinc, iodine and tyrosine are needed. Ensure you include foods high in this minerals are incorporated in the diet. For those with Hashimoto thyroiditis, iodin supplements should not be added because they may worsen the condition. You need to consult with your doctor before any steps are taken.
