Overview
Impetigo is primarily diagnosed clinically. Some laboratory tests can also be used to confirm the involved pathogen and to focus the treatment on that pathogen in particular. These include gram stain and culture and senstivity.[1][2]
Laboratory Findings
Impetigo is usually diagnosed clinically. Some laboratory tests can also be used to confirm the involved pathogen and to focus the treatment on that pathogen in particular. Various laboratory tests that are used in the diagnosis of impetigo, include:[1][3]
- Gram stain
- Culture and sesntivity[4]
- Anti-DNA-ase B Test[5]
- Serological anti-DNA-ase B test can be performed to show past group A streptococcal infections.
- Biopsy[3]
- It is rarely done in case of recurrence of impetigo.
