[The calculation of hemoglobin concentration from blood and plasma densities, measured by the mechanical oscillator technique (author's transl)]. 1979

H Hinghofer-Szalkay, and H Holzer

Blood samples from patients were taken for the measurement of blood and plasma densities by the mechanical oscillator technique, and the hematocrit value and the hemoglobin content of the blood. The values for blood and plasma density permit the precise calculation of blood hemoglobin concentration and hematocrit. Thus, in addition to the calculation of total protein concentration of plasma (Holzer et al (1978) J. Clin. Chem, Clin. Biochem. 16, 391--395), measurement of the blood density yields two further relevant parameters. In total, only 3 ml of blood are needed for the measurements.

D006400	Hematocrit	The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
