Studies with the copper sulfate specific gravity method of blood analysis: I. hemoglobin, hematocrit and plasma protein values of normal Filipino students

ABSTRACT

1. Hemoglobin, hematocrit and plasma protein values calculated from the specific gravities of plasma and whole blood determined by the copper sulfate method in 85 normal male and 30 normal female Filipino students are reported2. The mean hemoglobin is 15.78 +/- 0.97 Gm./100 ml. for males; 13.83 +/- 0.70 Gm./100 ml. for females. The mean hematocrit value is 46.63 +/- 2.84 volume % (cells) for males and 40.97 +/- 2.24 volume % (cells) for females. The mean plasma protein concentration is 7.44 +/- 0.40 Gm./100 ml. for males and 7.41 +/- 0.31 Gm./100 ml. for females, with a mean of 7.435 +/- 0.38 Gm./100 ml. for all subjects3. The values obtained in this study are compared with values previously reported for normal Filipino adults and with values given by foreign authors for normal adults of other races4. The fact that our hemoglobin and plasma protein values are higher than any reported by previous workers on Filipino adult subjects indicates the need at present for a re-evaluation of our physiologic standards.
