We rely on our immune system to fight harmful bacteria or viruses—either on its own or with the help of antibiotics or antivirals—every day. Most of us recover quickly from infectious illnesses, and our immune system helps protect us from repeat infections in the future.
People with primary immune deficiency diseases (PIDDs), however, have an inborn defect in one or more parts of their immune system. They often cannot overcome infections, even with the aid of medicine.
If you answered “yes” to any of these questions, you may be at risk for PIDD. Consult with your doctor to get tested for an immune deficiency.
To diagnose a potential immune deficiency, your doctor will need to take a blood sample and ssend it to a lab for an initial screening test. If that test shows that you may be at risk for a PIDD, you'll need additional testing.
