Sinus culture
A sinus culture is a medical test used to identify bacteria, fungi, or other microorganisms causing sinus infections. It involves taking a small sample of mucus or tissue from the sinuses, usually through a nasal swab or fluid drainage. The sample is then sent to a lab, where it’s cultivated to see what microbes grow. This helps doctors determine the specific cause of the infection and select the most effective treatment, such as antibiotics or antifungal medications. Sinus cultures are especially useful when infections are persistent or resistant to initial treatments.
