Reference standard for packed cell volume.

Determination of packed cell volume by centrifugation.

Plasma proteins, packed-cell volume and requirements for alcuronium.

The relationship between alcuronium requirements and the plasma concentration of albumin and total globulin was investigated in 50 adult patients undergoing elective upper abdominal surgery. No significant correlation was obtained with the plasma proteins (g/100 ml plasma). A significant positive correlation between alcuronium requirements and plasma albumin X (1-PCV), especially in anaemic pat...

International Council for Standardization in Haematology (ICSH) recommendations for "surrogate reference" method for the packed cell volume.

The 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. In 2001, the International Council for Standardization in Haematology (ICSH) recommended a Reference PCV method, which is fully traceable to the ICSH reference hemoglobin method. Because of its c...

Steady state hemoglobin concentration and packed cell volume in homozygous sickle cell disease patients in Lagos, Nigeria

Background: Sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. The purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. Methods: A cross-sectional study was conducted among the sickle cell patients atte...

Deriving a useful packed cell volume estimate from haemoglobin analysis.

A method is described whereby the packed cell volume (PCV) of a blood sample can be estimated from the haemoglobin concentration. The method defines the relation existing between haemoglobin concentration and the PCV of blood samples and uses the mathematical formula thus obtained to estimate an unknown PCV value for a sample by extrapolation from the known haemoglobin value of the same sample....
