title: High-resolution particle analysis--its application to platelet counting and suggestions for further application in blood cell analysis.
abstract: The characteristics of an instrument for high-resolution particle analysis in flow are discussed. It employs a combination of hydrodynamic focusing, fluid resistors, and electronic techniques to achieve precision and ease of use heretofore unobtainable in a moderate-cost clinical instrument. Its application to whole blood platelet counting is discussed, and suggestions are made for its possible application to a wide variety of blood cell measurements.
