Human Respiratory Syncytial Virus is responsible for a majority of lower respiratory tract infections among infants between the ages of 6 months to 2 years and the elderly, with weakened immune systems. It is considered the most common cause for bronchiolitis and pneumonia in children below one year. Symptoms of RSV are mild, often indistinguishable from a common cold. But in some cases, RSV may cause severe bronchiolitis and require medical attention. There are multiple methods to detect RSV in the human body, like Rapid RSV antigen test, RSV RC-PTR molecular test or by using viral cultures. The most common Rapid RSV antigen is based on detection of antigens by secretion of IgM and IgA antibodies.
