The key is to define your T cell populations of interest with correct gating strategies and to back up your T cell subset findings with functional analysis of these subsets. Distinct T cell subsets, or differentiation states, can be identified based on the cell surface markers expressed and/or the effector . CD3, a T cell specific marker, is necessary to differentiate T cells from other populations, simply because CD4 and CD8 can be expressed by other cell types. The PBMC cell type I have the most experience with characterizing is T cells.
