description The LHCb experiment at the Large Hadron Collider specialises in high-precision measurements of flavour physics with hadrons containing $b$ and $c$ quarks. Lepton flavour universality tests provide an accurate and clear approach to scrutinising the Standard Model of particle physics. These proceedings report recent lepton flavour universality tests performed by the LHCb collaboration. For $b \to c \ell \nu$ transitions, it includes the first simultaneous measurement of $R_{D^*}$ and $R_{D^{0}}$ at a hadron collider, an updated $R_{D^{*}}$ measurement with hadronic $\tau$ decays using 2015-2016 data, and recent measurements of $R_{J/\psi}$ and $R_{\Lambda_c}$. In $b \to s \ell^+ \ell^-$ transitions, the most recent measurements of $R_{pK}$, $R_{K^{*+}}$, and $R_{K^0_{\mathrm{S}}}$ ratios are presented. Moreover, the simultaneous measurement of $R_K$ and $R_{K^*}$ is reported.
