Impetigo diagnosis is based on hx and appearance of the lesion. This approach is best described as:

• A. Laboratory confirmation
• B. Clinical evaluation
• C. Radiographic assessment
• D. Genetic testing

Answer: (B)

Diagnosing impetigo from the history and how the lesion looks showcases the value of clinical evaluation in dermatology. When the presentation is typical—contagious spread with honey-colored crusts after vesicles rupture, often around the mouth or nose, and with little systemic illness—turther testing isn’t needed to start effective treatment and infection control can begin right away. Laboratory confirmation, like Gram stain or culture, is useful only if the diagnosis is uncertain, the presentation is atypical, the infection isn’t responding to standard therapy, or there’s an outbreak where precise identification matters. Radiographic assessment and genetic testing don’t play roles in diagnosing impetigo.
