Do You Need a Referral for a Skin Biopsy?

A skin biopsy removes a small sample of skin for examination. A dermatologist may recommend it when a spot, lump, rash, or changing lesion cannot be identified confidently from an examination alone. The sampling method can vary: a shave biopsy takes a superficial portion, while a punch biopsy removes a small, round, deeper sample. The clinician chooses the method according to the lesion and the question being investigated.

A referral is an access step, not a diagnosis. The clinician who refers you may describe the concern, but the biopsy decision and consent discussion take place with the treating team.

Ask the clinic whether you can self-book or need a referral from a primary-care clinician or another specialist. Check whether your health plan has its own pathway. Before the appointment, note when the lesion appeared and any changes in size, shape, colour, surface, bleeding, crusting, itching, or tenderness. Bring a list of medicines, especially blood-thinning medicines, and mention allergies, bleeding problems, immune conditions, or previous reactions to local anaesthetic.

Do not remove a scab or apply strong treatments to the area just before assessment unless a clinician tells you to. Clear photographs showing change over time can also help explain the concern.

Seek prompt medical assessment for a spot that is changing, repeatedly bleeding, not healing, developing a persistent crust, or becoming an unusual dark or uneven lesion. Rapid change, a new firm growth, or a sore that keeps returning also deserves timely review. These features do not establish a diagnosis, but they should not be delayed while waiting for a routine cosmetic appointment.

Ask: Do I need a referral for this clinic? Why are you recommending a biopsy? Which biopsy method fits the lesion? How will the area be numbed and closed? How should I care for the wound, and when will the result be discussed?
