Vitamin A plays an important role in strengthening the eyesight and good performance of growth and to maintain the immune system in our bodies.

There is several methods to measure vitamin A deficiency.

The first method is called the concentration of Retinol serum, used to determine the response to treatment given to people with symptoms clinical.

The second method is known as the way to respond relative to the dose adjusted depending on the patient's oral small dose of Retinol.
