Question

Quizplus · Accepted Answer

Culture and sensitivity testing is recommended to identify the causative organism of external otitis (otitis externa). This involves taking a sample from the affected area and growing it on a culture plate, which can help identify the specific bacteria or fungus causing the infection. Sensitivity testing can also be performed to determine which antibiotics or antifungal agents would be most effective in treating the infection. DNA probe testing and Pap tests are not typically used to diagnose external otitis, and a hematocrit test is used to measure the percentage of red blood cells in the blood and would not be useful for diagnosing an external ear infection.
