Questions about this test
Is the settle plate test done on patients?
No, it checks the air in a room, not a person. Hospitals and labs use it for infection control.
Why is air quality checked in IVF labs?
Embryos are very sensitive to germs and air quality. Regular checks help labs keep conditions clean.
How often are settle plates done?
It depends on the area and the hospital's infection control policy. High-risk areas such as operating theatres are checked regularly.
