Medical swabs are crucial diagnostic and clinical instruments utilized for sample collection, wound care, and infection control in various healthcare environments. Constructed from materials like cotton, foam, polyester, or nylon flocked fibers, these swabs are specifically designed to safely collect, absorb, and transport biological specimens from the human body. They are vital in diagnostic testing, especially in fields such as microbiology, molecular diagnostics, and infectious disease identification, where precise sample collection is essential for obtaining reliable test outcomes.
