Description
Why It’s Done:
This test is often done when there is a suspicion of infection caused by anaerobic bacteria. Common scenarios include:
• Intra-abdominal infections, such as appendicitis, peritonitis, or abscesses
• Dental or oral infections, where anaerobes are common in gum and tooth abscesses
• Soft tissue infections that develop after trauma or surgery, especially when there is a deep wound or an injury involving dirt or foreign materials
• Pneumonia or other respiratory infections caused by aspiration (inhaling food, liquid, or saliva)
• Pelvic infections such as endometritis or abscesses following surgery or childbirth
Symptoms suggesting the need for this test may include:
• Fever
• Pain and swelling at an infection site
• Foul-smelling discharge from a wound or abscess
• Abdominal pain or tenderness
• Respiratory issues if the lungs or pleura are infected
Preparation:
• No special preparation is required for most patients, but preparation may vary depending on the type of sample collected.
• If the test is done using a wound swab, surgical specimen, or body fluid, the sample should be obtained before the patient starts antibiotics to ensure accurate results.
• Blood culture may need specific collection techniques, as anaerobes are sensitive to exposure to air.
• Inform your healthcare provider about any recent antibiotic use, as this could affect the growth of anaerobic bacteria.
• Avoid using antiseptics or disinfectants near the infection site just before sample collection, as they may interfere with the bacteria’s growth.
