an opening, as in the probe of an electrical impedance or electron-optical cell counter, through which blood cells and other formed elements in diluting solution pass in single file.
a very stable cyanide and hemoglobin compound that results when a solution of potassium ferrocyanide is added to blood, lysing the red blood cells and releasing their hemoglobin content.
electrical impedance cell counter
an automated hematology instrument, such as the Beckman Coulter and Abbot Cell Dyn instruments, that analyze formed elements in the blood on the basis of their impedance of an electrical.
a technique that analyzes cells as they are forced through a detector system; this system could be an electric current a light or laser beam, or fluorescent dyes.
a hemotology control that is certified to be highly stable over its entire life; used to set the electronics of automated hematology instruments.
an artificial blood, containing both human and animal cells, that is used to check the stability of electronic setting of automated hematology instruments.
light scattering (optial counting) method
the method of studying formed elements in the blood that depends on their interruption of a beam of light from a laser lamp.
QBC (quantitative buffy coat) calibration check tube
the tube used with a QBC instrument to perform a daily quality control check. It gives a set of expected values and acceptable deviation values for each parameter
