Studies with the copper sulfate specific gravity method of blood analsis: II. comparison with a standard method and a micro method of hemoglobin determination

ABSTRACT

1. Hemoglobin values obtained on 60 blood samples with the CuSO(4) specific gravity method showed no significant difference from parallel determinations using Ponders a of Wongs standard method2. Evelyns micro method of hemoglobin determination gave significantly higher results than those obtained by the CuSO(4) specific gravity method and the modified Wongs method3. The nomogram devised by Van Slyke et al. is applicable to the Filipino subjects in this study. (Conclusions)
