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