Antibiotic Sensitivity Test

Top of the page

Topic Overview

An antibiotic sensitivity (or susceptibility) test is done to help choose the antibiotic that will be most effective against the specific types of bacteria or fungus infecting an individual person.

Some types of bacteria or fungus are resistant to certain antibiotics because of differences in their genetic material (genes). Infections caused by resistant bacteria or fungi are not cured by treatment with those antibiotics.
