Full counting statistics is a powerful tool to characterize the noise and correlations in transport through mesoscopic systems. In this work, we propose the concept of conditional spin counting statistics, i.e., the statistical fluctuations of a spin up (down) current given the observation of a given spin down (up) current. In the context of transport through a single quantum dot, it is demonstrated that a strong Coulomb interaction leads to a conditional spin counting statistics that exhibits a substantial change in comparison to that without Coulomb interaction. It thus can be served as an effective way to probe the Coulomb interactions in mesoscopic transport systems.
