    Cell Phone Shopping? You May Be Allergic to Some

    Nov. 9, 2012 -- If you're allergic to the metals nickel or cobalt, you may want to consider that when you pick a mobile phone.

    In a new study, researchers tested new and used mobile phones for nickel and cobalt. Some people are allergic to those metals. The allergies can cause skin redness, swelling, itching, and blistering where the metal touches your skin.

    Some of the BlackBerry phones studied had nickel in them. Many of the flip-phones studied had both metals.

    None of the iPhones or Androids studied tested positive for either metal, says researcher Luz Fonacier, MD, of Winthrop University Hospital in Mineola, N.Y., and State University of New York Stony Brook.

    She says wear and tear may result in more nickel being exposed. "In those phones that looked like the keypad had a lot of wear and tear, they were more likely to test positive for nickel."

    "In the BlackBerries, the nickel was found mostly on the keypads,'' she says.

    What if you don't want to give up the model you have despite that rash? "If you really love your cell phone, use an earpiece or use a cover," Fonacier says.

    "If you are severely allergic, you should consider getting a cell phone with no nickel," she says.

    Fonacier will present her findings Monday at the American College of Allergy, Asthma & Immunology annual meeting in Anaheim, Calif.

    Industry Responds

    Research In Motion (RIM), which makes BlackBerries, reviewed the study findings. "Research In Motion takes careful steps to design all BlackBerry smartphones with no exposed nickel on the exterior surface," says Krista Seggewiss, a company spokeswoman.
