The basic difference between CNS 2 and CNS 3 status in the definition, is the presence of > 5 WBC/ microL in CNS 3 and the presence of fewer WBCs in CNS 2 status ( along with the presence of blasts in both CNS 2 and 3 status). How does this difference of WBCs in cytospin impact the risk to classify them as a different CNS status ?
