Abstract
An object of the present invention is to provide a hemoglobin measurement reagent and measurement method that allow for more accurate measurement of the amount of hemoglobin by suppressing a decrease in a measured value of hemoglobin triggered by the addition of haptoglobin. The reagent for measuring hemoglobin of the present invention includes: an insoluble carrier immobilizing an anti-hemoglobin antibody; and an insoluble carrier immobilizing an anti-haptoglobin antibody. The method for measuring hemoglobin in a specimen of the present invention includes: a step (1) of mixing a specimen with haptoglobin and forming a hemoglobin-haptoglobin complex to obtain a sample containing the hemoglobin-haptoglobin complex; and a step (2) of bringing the sample obtained in the step (1) into contact with the insoluble carrier immobilizing an anti-hemoglobin antibody and the insoluble carrier immobilizing an anti-haptoglobin antibody to cause immunoagglutination.
