The influence of extraneous factors on Coulter S measurement of the mean corpuscular volume.

چکیده
Alteration in the temperature of the Isoton diluent in a Coulter model S counter over a range of possible laboratory working temperatures produced a change in the mean corpuscular volume using EDTA and dipotassium acid citrate dextrose blood and a commercial control, 4C. Contamination of the Isoton diluent with hypochlorite solution, used to clean the Coulter model S, may increase the mean corpuscular volume of EDTA blood without altering other measured parameters. Attention to both these points is required in assessing quality and calibrating the machine.

The red cell osmometer. A useful inaccuracy in measurement of mean corpuscular volume in hyperosmolar states.
The Coulter S Counter gives a value for mean corpuscular volume which does not necessarily reflect red cell size in vivo. This phenomenon may be used in early diagnosis and hence prevention of the 'hyperosmolar syndrome'.
متن کاملRed cell size as measured by the Coulter model S.
The MCV (mean corpuscular volume) was examined by the Coulter model S. It was found that the MCV measured by the Coulter S was larger than the generally accepted range 82 to 92, or 76 to 96 mu(3). The range in 500 healthy individuals was 82.2 to 100.6 mu(3). It was also found that the mean MCV became larger with increasing age. No sex difference was found. The low MCV by manual methods was gene...

متن کاملThe Response of Hematological Factors to Home-Based Exercise Rehabilitation and Center-Based Cardiac Rehabilitation in Coronary Artery Disease
Background: Hematological disorders such as increased white blood cells and platelets (elevated white blood cell and platelets) in coronary heart disease (CHD) are associated with increased mortality. Exercise could specifically influence hematologic factors. The purpose of this study was to survey the response of hematological factors to home-based exercise rehabilitation and center-based card...
متن کاملClinico-hematological profile of megaloblastic anemia.
Subject and Methods Twenty nine children (age range 3 months to 12 years) diagnosed as megaloblastic anemia over a period of three year (March 1993 to March 1996) were prospectively studied. All anemic children admitted with or without bleeding manifestations had their peripheral blood smear examined. Complete hemogram including platelet count and mean corpuscular volume (MCV) were also carried...
