Nickel Alert is a ready-to-use dimethylglyoxime (dmg) spot test for nickel. The nickel test is pre-mixed and pre-measured for both accuracy and convenience. This reduces mess and inaccurate test results. Nickel Alert is safe and easy to use. It will not harm metal items.

Nickel Alert (dmg spot test) is sensitive enough to detect the presence of free nickel at a level as low as 10 ppm (parts/million)—a threshold below which only individuals with the most pronounced sensitivity to nickel would experience a reaction. 

Recommended by leading dermatologists and allergists.


Squeeze 2-3 drops of Nickel Alert onto a cotton swab. With the swab, rub the metal item firmly for 15-30 seconds.. A pink-red color on the swab indicates nickel.

Do not reuse the swab.

To demonstrate a positive test, test a nickel coin. It contains 25% nickel and will turn the swab pink indicating nickel is detected.

Nickel Alert can be used to retest items coated with Nickel Guard®to verify protective barrier is in place. 

Nickel Alert should be used in well-ventilated areas.

Shipping Notice: Nickel Alert contains a flammable liquid and must be shipped via Surface Mail Only; it requires ORMD labeling to ensure it is not shipped via air. These precautions can add to delivery times.



Nickel Alert, Nickel Guard and Nickel Solution® are intended for use only on metal items; these items should be tested in an inconspicuous place.

Nickel Alert will not harm metal, even in delicate heirloom jewelry. However, if the item being tested has been coated, such as with varnish or antique finishes, the coating can be dissolved with the use of Nickel Alert.
