  • DEVICE AND METHOD FOR BLOOD HEMOGLOBIN MEASUREMENT WITHOUT CARBOXYHEMOGLOBIN INTERFERENCE
    Publication number: 20200182778
    Abstract: A method for blood haemoglobin measurement without carboxyhaemoglobin interference comprises converting oxyhemoglobin, deoxyhemoglobin and methemoglobin into a methemoglobin derivative, i.e. Imidazole-methemoglobin. Imidazole-methemoglobin and carboxyhemoglobin are collectively quantified by the reflectance spectroscopy of the matrix at 525 nm, the isobestic point between Imidazole-methemoglobin complex and carboxyhemoglobin molecule.
    Type: Application

  • Device and method for blood hemoglobin measurement without carboxyhemoglobin interference
    Patent number: 10564094
    Abstract: The present invention provides a device and a method for blood haemoglobin measurement without carboxyhaemoglobin interference. In the present device and method, oxyhemoglobin, deoxyhemoglobin and methemoglobin are converted into a methemoglobin derivative, i.e. Imidazole-methemoglobin. Imidazole-methemoglobin and carboxyhemoglobin in the matrix are collectively quantified by the reflectance spectroscopy of the matrix at 525 nm, the isobestic point between Imidazole-methemoglobin complex and carboxyhemoglobin molecule.
