Measuring the conserved charge fluctuations in the matter created by heavy ion collisions is an essential way to learn about the degrees of freedom that carry the charge. It also plays key role in the search for a possible critical end point. Such fluctuations can be charactered by the corresponding susceptibilities that can be computed by models and lattice QCD methods. We discuss what we can learn from these susceptibilities. In particular we examine the viability of describing these susceptibilities in the 1~2Tc regime by using models that are either weakly coupled (as per quasi-particle models) or strongly coupled (as per holographic models) .
