Accurate diagnosis of pustular skin lesions is crucial for effective treatment. Discover the key tests that help pinpoint the cause.

Clinical Examination
A thorough clinical examination is the first step in diagnosing pustular lesions. Doctors look at the location, size, and appearance of the pustules. They also consider any accompanying symptoms like fever or joint pain to guide further testing.
Laboratory Tests
Laboratory tests can help identify whether pustules are due to infections or other causes. Common tests include skin swabs for bacteria, viral cultures, and fungal examinations. Each test targets specific pathogens to determine the right treatment path.

The Role of Biopsies
Sometimes, a skin biopsy is needed to get a closer look at the pustules. This involves taking a small sample of skin for detailed analysis. Biopsies can reveal inflammation patterns and help rule out infectious causes.
