We prove that a recently derived correlation equality between conserved charges and their associated conserved currents for quantum systems far from equilibrium [O.A. Castro-Alvaredo et al., Phys. Rev. X \textbf{6}, 041065 (2016)], is valid under more general conditions than assumed so far. These correlation identities, which give rise to a current symmetry somewhat reminiscent of the Onsager relation, are also shown to hold in any space dimension and to imply a symmetry of the non-equilibrium linear response functions.
