Consultant-Led Allergy Patch Testing in Central London
Allergy Patch Testing at LSDC Healthcare is delivered by consultant dermatologists with expertise in inflammatory skin disease and occupational dermatitis.
Patch testing identifies delayed-type (Type IV) hypersensitivity reactions responsible for allergic contact dermatitis, allowing precise avoidance strategies and targeted treatment.
Testing is performed in a private, consultant-only setting in the City of London, with structured interpretation and clear, practical guidance.
What is Allergy Patch Testing?
Allergy Patch Testing is a diagnostic procedure in which small amounts of standardised allergens are applied to the skin (usually the upper back) under occlusion.
The skin is assessed over several days to identify delayed allergic reactions, which typically develop 48–96 hours after exposure.
It is the gold-standard investigation for allergic contact dermatitis.

What does allergy patch testing diagnose?
