Background

Concomitant reactions to palladium chloride (PdCl2), sodium tetrachloropalladate (Na2PdCl4), and nickel hexahydrate sulphate (NiSO4·6H2O) are very common during patch testing and have mainly been explained by cross-sensitisation. Whether there is variation in reactivity to palladium or covariation to nickel and palladium is not known.
