Child Growth Immunization

The Right Age for Children to Get an Immunity Test

At a young age, children are still experiencing growth and development. Not only physical condition, but the body’s immunity continues to be improved to be able to provide protection from all dangers that enter and want to attack the body. That is, it is necessary to do a child’s immunity test to find out how the condition of his immune system is.

Immunity test or called immunoglobulin test is done to measure the level of certain immunoglobulins or antibodies in the blood. Antibodies are protein compounds created by the immune system to fight bad antigens, such as bacteria, viruses, and germs that cause disease.

Basically, the body makes different immunoglobulins to fight different antigens. Simply put, the antibodies that are created to fight chickenpox are certainly not the same as the antibodies that are made to treat mononucleosis. In some cases, the body accidentally creates antibodies against the body by fighting off healthy organs such as damaged organs. This condition is called an autoimmune disorder.

Understanding the Function of a Must-Know Immunity Test

Type of Antibody

Normally, the body has 5 (five) sub-classes of antibodies, namely:

  • Immunoglobulin A or IgA is found in mucous membranes in very high amounts, especially those lining the respiratory tract, digestive tract, saliva, and eyes.

  • Immunoglobulin G or IgG is a type of antibody that is abundant because it is found in all body fluids. These antibodies help protect the body from viral and bacterial infections.

  • Immunoglobulin M or IgM found in blood and lymph fluids. These antibodies are formed by the body first to fight new infections.

  • Immunoglobulin E or IgE is most associated with allergic reactions. These antibodies are found in the lungs, skin, and mucous membranes.

  • Immunoglobulin D or IgD in small amounts in the blood. These antibodies are the least in number.

When Should a Child Immunity Test Be Done?

Not a few mothers ask, when should the child’s immunity test be carried out. This condition is more common in mothers who have just had their first child. Naturally, because the mother’s experience in child growth and development is still minimal. Then, when is the best time to do this immunity test on children?

In fact, children have been given immunizations since they were born and then continue until they turn 18 years of age. At this age, it can be said that by the age of 18, the child’s immunity is fully developed and is able to protect the body from the threat of various diseases. The interval of giving for each type varies, with the number of repetitions that are not the same. Simply put, the immunity test is done depending on the indication, when the child is mature and in good health.
