Abstract
The manual, spun Packed Cell Volume (PCV, hematocrit) is a key measurement on which are based hematology instrument calibration, reference range determination and assignment of values to calibrators/controls. Until now, however, no true reference method for the PCV has existed. The International Council for Standardisation in Haematology (ICSH) which met in Montpelier, France in May 2001 has now recommended a reference method for the PCV. This reference PCV method is fully traceable to the ICSH reference method for haemoglobinometry. Using carefully defined capillary tubes, the reference PCV can be calculated as the ratio between the hemoglobin of whole blood and the hemoglobin of packed red blood cells with all plasma removed. The ICSH intends that this reference protocol be used primarily by manufacturers of capillary microhematocrit tubes, liquid calibrators and multichannel analyzers.
