<p>PROBLEM TO BE SOLVED: To provide a system for measuring a plasma component of a mammal rapidly and inexpensively without using an analytical reagent and without discharging harmful drain. SOLUTION: This rapid measuring method of a plasma component of a mammal by spectrum information in a visual and near-infrared region is characterized by measuring an absorbance in the visual and near-infrared region having a wavelength of 400-2,500 nm by using a near-infrared spectrophotometer relative to separated plasma in measuring the plasma component of the mammal, calculating a primary differential and a secondary differential of the absorbance, using the absorbance, and the primary differential and the secondary differential of the absorbance in the visual and near- infrared region as independent variables, selecting independent variables to the number of two to ten having high explanation power from among the independent variables, predicting neutral fat, inorganic phosphorus, potassium, lactate dehydrogenase and an albumin-globulin ratio in the plasma from the information on the independent variables having high explanation power, and realizing measurement based on the predicted values.</p> |
