The assumption of a Friedmann-Lema^itre-Roberton-Walker (FLRW) Universe is
one of the fundamental pillars of modern Cosmology. It is crucial to confront
it against cosmological observations in order to confirm (or rule out) the
validity of the $Lambda$CDM paradigm. We perform a consistency test of the
FLRW metric using measurements of both radial and transversal modes of Baryonic
Acoustic Oscillations in a model-independent fashion, finding null evidence for
a departure of such hypothesis at a $2sigma$ confidence level.
