What metals are tested in a patch test?

Metals with the highest allergic patch-test reaction rates were nickel, gold, manganese, palladium, cobalt, Ticonium, mercury, beryllium, chromium, and silver. Metals causing no allergic patch-test reactions were titanium, Vitallium, and aluminum powder.

Which of the tests is recommended in suspicion of metal allergy?

At this time, the scientific literature and these authors thus favor the skin patch test as the best available test to evaluate potential metal hypersensitivity reactions, both prior to and following implantation.

Is there nickel in titanium?

While titanium is considered to be “nickel free,” and titanium alloy is commonly used as an alternative to stainless steel alloys for patients who may have nickel sensitivity, it is possible that trace amounts of impurities including nickel could be contained within these materials.

Can you be allergic to stainless steel implants?

Some people have allergies or sensitivities to metal and others may worry about developing one. These are rarely problems when it comes to implants. Hypersensitivity or allergy can occur after contact with various metals.

What are the symptoms of a metal allergy?

The result: redness, itching, swelling or a rash, with skin blistering or scaling at the site. The symptoms of metal allergy range from mild to severe. Each time you’re re-exposed to the offending metal, your skin reacts in the same way.

How do you get tested for a metal allergy?

Metal-LTT is a blood test which tests immune cell responses to different metals. Metal-LTT testing can identify which people are susceptible to metal sensitivity. Metal-LTT testing can also identify which specific metals cause sensitivity responses and which specific metals do not cause excessive immune reactions.

Is titanium OK for nickel allergy?

Avoid jewelry that contains nickel. Purchase jewelry that’s made of materials that aren’t likely to cause allergic reactions. Look for jewelry made from such metals as nickel-free stainless steel, surgical-grade stainless steel, titanium, 18-karat yellow gold, or nickel-free yellow gold and sterling silver.

Is titanium safe for nickel allergy?

Make sure your jewelry is made of surgical-grade stainless steel or either 14-, 18- or 24-karat yellow gold. White gold may contain nickel. Other nickel-free metals include pure sterling silver, copper, platinum, and titanium. Polycarbonate plastic is okay.

Can your body reject a metal implant?

‘Over time their body becomes sensitised to react to it and so when it comes to later in life and needing an implant — many of which contain nickel or metals that the body’s immune system “sees” as nickel — they reject the implant.

How do you know if your body is rejecting a metal implant?

Signs and symptoms of metal hypersensitivities can range from small and localized to more severe and generalized. Limited reactions can appear as a contact dermatitis on the skin that has been exposed to the metal. The skin may appear red, swollen, and itchy. Hives and rashes may also develop.

How long does a metal allergy test take?

The entire series of tests will take about a week to complete. You will typically have an answer on the last day of testing, although the blood tests for nickel and cobalt allergy take about 2 weeks for the results.

How do you treat metal hypersensitivity?

If the dermatitis is more significant, the doctor can also prescribe corticosteroid creams and ointments to reduce the local inflammation. The doctor can also prescribe oral antihistamines to further reduce the allergic reaction. Oral corticosteroids can also be used, but they can cause problematic side effects.
