Ear drainage culture
Ear Drainage Culture
An ear drainage culture is a lab test performed to detect infections caused by bacteria or fungi. It typically involves taking a sample from the ear and collecting it in a sterile container for laboratory analysis. By identifying the source of the infection, doctors can treat it with antibiotics or antifungals.
Preparations
Most ear drainage cultures are done on an outpatient basis. Therefore, no major preparations are required. Before collecting the sample, the doctor may clean the area around your ear to move any wax or dirt that might be present.
Procedure
During the procedure, the doctor will:
- Clean the outside of the ear with a sterile cloth.
- Using a sterile cotton swab, collect a sample of drainage from the ear.
- Place the sample in a sterile container.
- Send the container to the laboratory for analysis.
Types
Ear drainage cultures are most commonly used to diagnose and treat infections of the middle ear, such as otitis media. They may also be used to diagnose infections in the outer ear or ear canal.
Risks
Ear drainage cultures are generally safe and pose no risks. However, if the procedure is not performed properly, infection of the ear can occur.
Why It's Done
Ear drainage cultures are done to identify the cause of infections in the ear. This helps doctors determine the type of microbes or fungi causing the infection and then use the appropriate antibiotics or antifungals to treat it.
When To Do It
An ear drainage culture should be done if a doctor suspects an infection in the ear. Common symptoms include pain, itching, swelling, redness, and discharge. Ear infections can also cause hearing loss and dizziness.
