Nusal swabs are specialized nasal swabs designed for collecting specimens from the nasal cavity, often used for diagnostic purposes such as detecting respiratory infections, including COVID-19, influenza, and other viral or bacterial pathogens. These swabs are typically made of soft, flexible materials like nylon or polyester to ensure comfort and minimize irritation during sample collection. They are sterile, single-use devices with a long shaft for easy insertion and precise collection. Nusal swabs are commonly used in clinical settings and are an essential tool for accurate and non-invasive testing in healthcare. Proper handling and storage are crucial to maintain sample integrity.
