Who should consider testing?

  • Before a joint replacement or implant: orthopedic and dental surgeons often refer patients for metal allergy evaluation before implanting hardware containing nickel, cobalt or chromium alloys
  • Persistent skin rashes: Recurring eczema or contact dermatitis on the wrists, earlobes or abdomen is a common sign of metal contact sensitivity
  • Reactions to dental work: oral symptoms, gum irritation, or skin rections following dental procedures may indicate sensitivity to metals used in crowns, braces, or fillings
  • Reactions to everyday items: Redness or itching where jewelry, watch bands, eyeglass frames or clothing hardware touches the skin is hallmark of metal hypersensitivity

How does patch testing work?

  1. Application (day 1): Small adhesive panels containing metal allergens are placed on your back. They stay in place for 48 hours during which you'll need to keep the area dry.
  2. Removal and first read (day 3): The panels are removed and an initial reading is performed. Early reactions help us assess what your immune system is responding to.
  3. Final reading (day 4-7): A follow-up visit allows us to capture delayed reactions that develop over several days which is important for accurate, complete results.
  4. Results and guidance: We review your results together and provide a written list of metals and products to avoid, and safe alternatives where relevant.
