Questions about this test
Why are staff noses swabbed?
Some people carry bacteria such as Staphylococcus aureus in the nose without being ill. Finding carriers helps prevent spread in hospitals.
Is the sterility swab test for patients?
Mostly no, it is part of hospital infection control. Some patients may be screened before surgery.
What happens if growth is found?
The area is cleaned again and retested, or staff may be given treatment to clear the germs. This is part of routine safety checks.
