Autoimmune Pulmonary Alveolar Proteinosis, or aPAP, is a rare life-threatening lung disorder that occurs in about seven out of every one million people in the general population. It occurs when an oily substance that is normally present in the air sacs of the lungs builds up and causes a feeling of breathlessness that can worsen over time. The diagnosis of aPAP is challenging because the symptoms are nonspecific and similar to other more common pulmonary diseases. Ask your pulmonologist to confirm or rule out aPAP at no cost with the help of aPAP ClearPath™, a simple, accurate, and noninvasive autoantibody blood test.
