against infection, and immunology is the study of the immune system. If your child's immune system doesn't work properly, it can cause problems like severe, frequent or unusual infections and autoimmune disorders. That's why Cook Children's Immunology team is here.</p> <h2>What we do</h2> <p>Our immunology team evaluates, diagnoses and treats children who were born with errors in their immunity system, also known as primary immune deficiency disorders (PIDDs). There are more than 450 of these conditions. These patients are at risk to serious infections and illnesses. Some of these conditions can run in families and be passed from generation to generation.</p> <h2>Services</h2> <p>As a patient of our Immunology program, your child will receive an evaluation and treatment by our board-certified doctor in immunology. Our team provides consultation for the management of:</p> <ul> <li>Primary immune disorders</li> <li>Immune dysregulation disorders</li> <li>Hematopoietic stem cell transplantation</li> <li>Abnormal newborn screen</li> </ul></div> </div> </div> </div> </div> </div> </div> </main> <script defer="defer" src="/Util/Find/epi-util/find.js"></script> <script>
