Abstract
The result obtained with the macrophage electrophoretic migration (MEM) test depends upon selection of the macrophages used for measurement. From the wide spectrum of cells present in a guinea-pig peritoneal exudate, cells which just fill a square in the eyepiece grid of the Zeiss cytopherometer and contain clear liquid paraffin droplets are best suited for migration time measurement.
