Metal Allergy Testing.

 

Surgical implants have a wide array of therapeutic uses, most commonly in joint replacements, but also in repair of pes excavatum and spinal disorders, in cardiac devices (stents, patches, pacers, valves), in gynaecological implants, and in dentistry.

 

Many of the metals used are immunological active, as are the methacrylates and epoxies used in conjunction with several of these devices.

 

The Allergy Clinic offer a screening services to uncover allergic responses to surgical components via patch testing.

 

Metal allergies can present atypically as failure of the device, with nonspecific symptoms of localised pain, swelling, warmth, loosening, instability, itching, or burning; localised rash may also be present. 

 

By identifying a patients response to the most common metals -

 

  • Nickel,

  • Titanium

  • Cobalt,

  • Chromium

 

all of which are implicated in implant failure due to metal sensitisation; surgeons can now use this information when choosing implants for individual patients.

 

Methacrylate-based cements are also important contributors to allergies. 

Metal allergy testing is governed by Mr Paul Nicholson, carried out by The Allergy Clinic via patch testing experts.
