We compared a nephelometric method and a radial immunodiffusion (RID) assay for the measurement of retinol-binding protein in samples of serum from children with malignancies. The mean (+/- standard deviation) retinol-binding protein concentration as measured by the Behring Nephelometer was 31.0 +/- 15.6 mg/l; the mean by RID was 31.2 +/- 15.7 mg/l. This difference was not statistically significant by Student's t test (P = 0.6), and the correlation coefficient (r) was 0.87. Thus, the Behring Nephelometer method measures retinol-binding protein rapidly and as accurately as radial immunodiffusion.

UI MeSH Term Description Entries
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.

D009391 Nephelometry and Turbidimetry Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering. In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured. In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam. Turbidimetry,Nephelometry,Turbidimetry and Nephelometry
