Effect of the sequence of pull of bone marrow aspirates on plasma cell quantification in plasma cell proliferative disorders.

First pull BMA smears were of superior quality but inadequate in one-tenth of samples. Second pull smears underreported PC% and recovery of PC compartment was poorest on FCMI. Concurrent bone marrow biopsy and use of the first pull sample for FCMI along with acquisition of a higher number of cells on FCMI may enhance the quality of assessment in PCPDs.
