The results obtained showed that 97% viable cells were obtained using the three concentrations of the Ficoll/Hypaque. For purity, 12% Ficoll concentration separated cells were contaminated with others blood cells, while 9 and 10% separated cells were pure. When cells count was applied for the pure isolated cells, the cells isolated on 10% Ficoll/Hypaque concentration showed the best highest count compared to 9% with p = 0.003. Cells isolated using 10% Ficoll/Hypaque well proliferated when stimulated with Phytohaemaggglutnin (PHA) mitogen. Keywords: Ficoll/Hypaque;viable cells;peripheral blood;PHA;monocytes
