A method of analyzing blood using a near infrared apparatus, in which monochromatic near infrared light in a wavelength range of 700 nm-1100 nm from the slit of the near infrared apparatus is applied to a ceramic plate through an optical fiber to measure a transmitted light intensity of the ceramic plate, which is a reference material for spectrum measurement. Next, in place of the ceramic plate, a blood collection tube containing a blood sample which has been stabilized at a predetermined temperature by a water bath has the near infrared light applied thereto. A so-called near infrared absorption spectrum in which absorbance has been plotted against wavelengths is obtained and information about object characteristics of the blood is extracted from the spectrum data using a calibration equation predetermined using the near infrared apparatus in relation to blood specimens with different, known object characteristics. |
