    摘要: Disclosed is an integrated device for faeces sampling and occult blood detection, which has functions of quantitative collection, dissolution, filtration, detection with immune test strips of the faecal sample, and is convenient to carry and operate, and the device does not leak any liquid during storage, transportation and detection. The device can accurately collect a constant sample with no pollution and leakage, and can quickly determine results of occult blood without the aid of other items. The device can detect faecal occult blood at any time and at any place, can help to overcome the problem of low rate of inspection due to the inconvenience of faeces submission and inspection, further promote the detection of faecal occult blood, and can improve the early diagnosis and screening rate of colorectal cancer of the population.

    摘要: A method is provided for measuring glycated hemoglobin in a hemoglobin-containing sample which comprises reacting glycated hemoglobin in the hemoglobin-containing sample with an enzyme that catalyzes a reaction of oxidizing the glycated hemoglobin to generate hydrogen peroxide, in the presence of at least one anionic surfactant selected from the group consisting of N-acyl taurine in which a hydrogen atom of the amino group may be substituted with a substituent, alkyl sulfoacetic acid, polyoxyethylene alkyl ether acetic acid, N-acyl amino acid in which a hydrogen atom of the amino group may be substituted with a substituent, polyoxyethylene alkyl ether phosphoric acid, polyoxyethylene polycyclic phenyl ether phosphoric acid, alkyl phosphoric acid, and salts thereof, to generate hydrogen peroxide, and measuring the generated hydrogen peroxide.
