Abstract

1. The factors influencing blood conductivity have been noted.

2. An accurate apparatus has been designed to measure blood and plasma conductivity.

3. A new cell has been designed to measure conductivity of blood.

4. Through studies on normal blood before and after dilution, a correlation has been shown to exist between blood conductivity and the red cell count.

5. The form factor for normal human red cells has been determined to be 1.393.

6. A mathematical equation is presented relating red cell count with conductivity for normal blood.

7. The factor C on the basis of 33 determinations has been calculated to be 10.80.
