title: A comparative study for the enumeration of peripheral blood white cell counts below 2.0 x 10(9)/1 using counting chambers and the Coulter Counter model "S".
abstract: Low white cell counts are performed in many laboratories by a visual method as the method of choice. In this study, the visual count has been compared to that obtained by the Coulter Model "S". The results obtained by the two methods show very close correlation, thus allowing the Coulter Model "S" to be used with confidence for all low white cell counts provided certain precautions are taken.
