Iodine test (semi-quantitative determination)

Preparing the patient for a urine iodine test It is necessary to perform a hygienic toilet of the external genitalia beforehand. Collect morning urine in a clean container and deliver it to the laboratory no later than 2 hours after collection.

Urine is an important biological fluid that reflects the functioning of the kidneys and the general condition of the body. One of the diagnostic methods using urine is the iodine test or iodine sample. This test allows you to assess the concentration of urea in the urine, which is an important indicator of the condition of the kidneys and metabolic processes in the body.

What is an iodine test? An iodine test, or iodine test, is a simple and affordable method for assessing the concentration of urea in urine. It is based on the interaction of iodine with urea, which is expressed in the form of a reaction in which the urine changes its color. Usually, a 5% iodine solution is used, which is added to the collected morning portion of urine. Depending on the concentration of urea, urine can take on different colors from yellow-green to dark blue.

How is an iodine test performed? To perform an iodine test, you will need the following materials and tools:

1. Morning urine sample (about 30-50 ml).
2. 5% iodine solution.
3. A clean plastic or glass container for urine.
4. Mixing stick.

Instructions for conducting an iodine test:

1. Collect your morning urine in a clean container. It is important to use the first urine sample after waking up.
2. Add a few drops of 5% iodine solution to the urine. The total amount of iodine can range from 2 to 5 drops depending on your needs.
3. Completely dissolve the iodine in the urine using a stick or spoon, gently stirring the liquid.
4. Watch for a change in the color of the urine within the first few minutes after adding the iodine. The reaction usually occurs very quickly.

Interpretation of results:

• If your urine turns purple, it indicates a high concentration of urea in your body. This may indicate kidney or metabolic problems.
• A pink or purple hue can also be the result of taking certain medications or dietary supplements.
• If the urine remains yellow or yellow-green, then the urea concentration is normal.

It is important to remember that the iodine test is not an accurate method of determining urea concentration and cannot replace professional medical advice and examination. This test can only serve as a guideline for checking the general condition of the kidneys and metabolic processes in the body. In case of any doubts or suspicions of kidney problems, be sure to consult a doctor for a more accurate diagnosis and treatment.
