Generate a step-by-step 96-hour patch test protocol for tattoo inks and body jewellery materials before a procedure.
Important: Patch testing does not guarantee a procedure will be reaction-free. Some reactions
only present at the full procedural dose. If you have a history of severe allergic reactions (anaphylaxis),
consult a dermatologist or allergist before any patch testing. This protocol is not a substitute for
professional allergy testing.
