Relationship between haemoglobin concentration and packed cell volume in cattle blood samples.
A convention that has been adopted in medicine is to estimate haemoglobin (HB) concentration as a third of packed cell volume (PCV) or vice versa. The present research set out to determine whether a proportional relationship exists between PCV and Hb concentration in cattle blood samples, and to assess the validity of the convention of estimating Hb concentration as a third of PCV. A total of 4...

Gruneberg, 1942; Meyerstein, 1942; Smith, 1944; Harris, Gilding, and Smart, 1951 ; Sabine and Nickolai, 1952) and those open at both ends (Gram and Norgaard, 1923; Van Allen, 1925a and b; Guest, 1938 ; Kato, 1938 and 1940; Miller, 1939 Hamre, 1940; Benditt, Straube, and Humphreys, 1946; Shils, Sass, and Goldwater, 1952). All these tubes suffer from drawbacks either in design or method of use. A...
متن کاملDistribution of Haemoglobin Level, Packed Cell Volume, and Mean Corpuscular Haemoglobin Concentration in Women in the Community.
The definition of anaemia in most published work appears to depend upon the demonstration of either a haemoglobin level or a mean corpuscular haemoglobin concentration estimation, or both, below levels chosen in a largely arbitrary fashion with little reference to the distributions of these variates in the population. Pryce (1960) stressed that "normal" haematological values derived from series...
متن کاملSteady 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...
متن کاملDeriving 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....
