Immunodeficiency is a condition in which the body has difficulty fighting off infections and diseases due to a weakened immune system. If your child is showing signs of frequent infections, particularly those that do not respond to antibiotics, they may have an immunodeficiency disorder. Other signs to watch for include poor growth, frequent or recurring infections, or frequent bouts of fever. If you are concerned your child may have an immunodeficiency disorder, it is important to speak to your doctor for further testing and evaluation.

How do you test a child’s immune system?

Testing a child’s immune system typically involves a series of tests to measure the level of antibodies and other immune system components present in their blood. This can include tests such as a complete blood count (CBC), a white blood cell count (WBC), and a lymphocyte count. Depending on the results of these tests, further tests may be recommended to identify any potential issues with the child’s immune system. In some cases, a skin test, such as a tuberculin test, may be used to assess the body’s response to a particular antigen.

How do I know if my child has an immune deficiency?

If your child is frequently sick and has difficulty fighting off infections, they may have an immune deficiency. Signs of an immune deficiency can include frequent ear infections, sinus infections, pneumonia, and bronchitis. Additionally, they may have difficulty recovering from colds or viruses, and may develop allergies to substances they were previously not allergic to. If you suspect that your child has an immune deficiency, it is important to make an appointment with your pediatrician or a specialist to discuss your concerns and get a proper diagnosis.
