What is it?
A skin biopsy is a minor procedure to take a small sample of skin so it can be examined under a microscope. It helps reach an accurate diagnosis when a lesion needs further investigation.
Who is it for?
People with a skin lesion or rash where a precise diagnosis is needed to guide treatment.
Benefits
- Accurate diagnosis from laboratory analysis
- Guides the right treatment plan
- Quick procedure under local anaesthetic
The procedure
The area is numbed with local anaesthetic. A small sample of skin is taken using the technique best suited to the lesion — such as a punch or shave biopsy — and the site is dressed. The sample is sent for laboratory analysis.
