US 2019/0101483 A1 · METHOD FOR PREDICTING ONSET OF CEREBRAL INFARCTION, METHOD FOR DETERMINING THERAPEUTIC EFFECT OF ERYTHROPOIETIC FACTOR PREPARATION, AND METHOD FOR DETERMINING STAGE OF CHRONIC KIDNEY DISEASE

Abstract

Disclosed is a method for assisting prediction of onset of cerebral infarction, based on the number of red blood cells contained in a blood sample collected from a subject, comprising the steps of: calculating an exponent value for the prediction 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, comparing the exponent value with a reference range, and suggesting that the subject develops cerebral infarction when the exponent value is outside the reference range.

A method for assisting prediction of onset of cerebral infarction, based on the number of red blood cells contained in a blood sample collected from a subject, comprising the steps of:

calculating an exponent value for the prediction 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,
comparing the exponent value with a reference range, and
suggesting that the subject develops cerebral infarction when the exponent value is outside the reference range.

A method for assisting determination of a therapeutic effect by an erythropoietic factor preparation, comprising the steps of:

for a blood sample collected from a subject at a first time point, 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,
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
suggesting 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.
