Hemoglobinometry: evaluation of a new method with a stable primary standard

Pathology, 1988
Using purified chlorohemin as a stable standard, a newly described hemoglobinometry method was evaluated. All blood samples as well as chlorohemin gave identical absorption spectra in an alkaline-detergent solution with a broad peak at 575 nm. Both the reagent mixture and the chlorohemin standard were stable for at least 250 days when stored between 8 ...

[42] Hemoglobinometry in human blood

open access: closed, 1981
Publisher Summary This chapter discusses hemoglobimetry in human blood. The hemoglobin concentration in whole blood is a highly expressive parameter in clinical and preventive medicine; therefore the standardization of an assay method with high precision and accuracy has been considered a problem of primary importance in clinical chemistry. A problem

Stable hemoglobin compounds in concentrated solution as reference for hemoglobinometry

Clinica Chimica Acta, 1969
Abstract Concentrated reference solutions of stable hemoglobin compounds (cyanmethemoglobin and azide-methemoglobin) can be prepared by adding a small volume of a concentrated reagent to washed red blood cells. Hemolysis is obtained by shaking with carbon tetrachloride; red blood cell stromata are removed by centrifugation and suction.

The calibration of automated instruments for accuracy in hemoglobinometry.

open access: closedAmerican journal of clinical pathology, 1977
The surveys of the College of American Pathologists indicate a consistent bias between the manual "reference" method for hemoglobin determinations and the Coulter S measurements. The Coulter S hemoglobin values are invariably lower; the difference averages 0.3 g/dl. The commonly used calibration methods for the Coulter appear to be subobtimal.
