Small enough for a physician's office and much cheaper than electronic devices that actually count erythrocytes, leukocytes, and platelets, the machine could offer real savings in the time spent between obtaining a sample and getting a report. Using a special float to spread out the buffy coat, and a fluorescent dye that stains nucleotide and leukocyte granules, the method is...References1. WARDLAWLEVINE SR.
