How Are Cellulitis and Abscess Diagnosed?
Published: Feb 06, 2024
Accurate diagnosis of cellulitis or abscess is key to effective treatment. Let's explore how these conditions are identified.
Contents
Clinical Examination
Diagnosis often starts with a physical exam. Doctors look for red, swollen, and warm areas on the skin. They may also check for fever and other signs of infection, which can help distinguish between cellulitis and abscess.
Laboratory Tests and Cultures
Lab tests are not always necessary for simple cases, but they can be helpful when the infection is severe. Blood cultures might be taken to identify the bacteria causing the infection, especially if the patient has underlying health issues.

Imaging Techniques
Ultrasound or MRI may be used to differentiate between cellulitis and abscess. Imaging helps visualize the pus collection in abscesses, guiding treatment decisions and procedures like drainage.
