1. A method of detecting whether a neoplastic cell having a heterogeneity index above a predetermined threshold is present in a neoplasia sample, the method comprising:
contacting the neoplasia sample with a labeled binding member specific for programmed death ligand 1 (PD-L1) to generate a labeled cell suspension;
cytometrically assaying the labeled cell suspension to obtain a per cell heterogeneity index comprising quantifying a number of PD-L1 molecules expressed per cell to detect whether a neoplastic cell that has a heterogeneity index above a predetermined threshold is present in the neoplasia sample.
