Are Allertest Ni results accurate?
Positive tests (red color) are very accurate for the presence of nickel. The dimethylglyoxime test is considered the standard test method for nickel and is used worldwide. However, occasionally a negative Allertest Ni result can be false. This may occur if other metals or contaminants interfere with the test. Some individuals are more sensitive to nickel than dimethylglyoxime tests can measure. If you have been diagnosed with a nickel allergy and the Allertest Ni test results are negative, but your skin reacts to a metal object you should discuss this with your physician. You may be allergic to other non-nickel substances in the object. Until the problem is resolved you should avoid exposure to the object. Contacting the product manufacturer may help determine if the metal object is manufactured with nickel.
