1. A method for assisting determination of a therapeutic effect by an erythropoietic factor preparation, comprising the steps of:
in a blood sample collected from a subject at a first time point, measuring a red blood cell count without treating red blood cells with a surfactant before measurement, measuring the red blood cell count after treating red blood cells with a surfactant, calculating a first exponent value from a first measured value indicating red blood cell count measured by electrical resistance measurement method and a second measured value indicating red blood cell count measured by optical measurement method;
administering the erythropoietic factor preparation to the subject;
for a blood sample collected from a subject at a second time point after administration of the erythropoietic factor preparation and after the first time point, calculating a second exponent value from a third measured value indicating red blood cell count measured by electrical resistance measurement method and a fourth measured value indicating red blood cell count measured by optical measurement method,
comparing the first exponent value with the second exponent value; and
determining, by a determination apparatus, that the erythropoietic factor preparation works well in the subject when the second exponent value is determined to be improved over the first exponent value.
