Swabs
Swabs are small pieces of cotton on a stick, often used for medical applications. They are used to collect bacteria, viruses, and other cells from a surface and can be used to prepare specimens for culture and other tests. Swabs may also be used to take samples from a person’s body, such as blood and secretions like mucus and saliva. After taking a sample, the swab is sent to a laboratory for analysis. Swabs are often used in laboratories to check for organisms that may cause infections and other medical conditions.
