The Rapid IgG Screen or RIgGS test could be useful in underserved areas with limited resources to help identify children with primary antibody deficiencies (PADs) who may be at risk for acquiring and spreading polioviruses. According to the latest research by a team led by Roger B. Peck, a research scientist and senior program officer at PATH, a global nonprofit based in Seattle, published in the Journal of Clinical Immunology, RigGS is a prototype point-of-care rapid screening device that differentiates between low immunoglobulin G antibody levels associated with agammaglobulinemia and normal levels. The researchers underlined the significance of their study as there are no rapid diagnostic tests available that can screen individuals for PADs at the point of care in low-income and middle-income countries. The study highlighted that a rapid diagnostic test will equip communities with an important tool to help identify undiagnosed cases of primary immunodeficiency diseases (PID) and limit prolonged shedding of vaccine polio virus.
