  We outline the evaluation of $n$-dimensional fermion traces
($n\in\mathbb{N}$) built by products of Dirac-$\gamma$ matrices suitable for a
uniform dimensional continuation. Such a continuation is needed for
calculations employing a dimensional regulator whenever intrinsically integer
dimensional tensors yield non-vanishing contributions. A prime example for such
a tensor is given by $\gamma_5$ for $n=4$. The main difference between
Dimensional Regularization (DREG) and a Dimensionally Continued Regularization
(DCREG) is that DCREG does not attempt to lift the algebra to continuous $d$
dimensions ($d\in\mathbb{R}$). As a consequence one has to properly deal with
evanescent structures in order to ensure the uniform application of the
regulator. In basic steps we identify evanescent structures in fermion traces
and show that their proper treatment is crucial for example when calculating
the $VVA$ anomaly in four dimensions. We checked that the performed
considerations enable the evaluation of Standard Model (SM) $Z$-factors within
DCREG up to including three loops.
