In this talk, I describe the uses of QCD inequalities and input from the recent lattice QCD calculations at finite isospin chemical potential to derive robust bounds on the EoS at finite baryon density. We find that the lattice data puts an upper bound on the baryon density of the symmetric nuclear matter at a given baryon chemical potential and a lower bound on the pressure as a function of the energy density. I also discuss additional constraints from perturbative calculations of the QCD EoS at high density derived in earlier work and causality to delineate robust bounds on the EoS of isospin symmetric matter at densities relevant to heavy-ion collisions.
