In studying the linear response of the dressed quark propagator in the presence of the variable external field, we derive a general expression for the vacuum susceptibility, based on the two-point external field formula in the Quantum Chromodynamical sum rule.

Then we use the expressions to calculate the renormalised axial vector, vector and tensor vacuum susceptibilities.
