The quantitative efficiency of the spleen colony assay in mice is discussed in the light of recent findings on the kinetics of colony forming cells. Arguments are presented showing that the f factor, the 2 hr CFU recovery fraction in the spleen, markedly over‐estimates the assay efficiency which is the ratio of the numbers of colony forming units and colony forming cells.
