1. A method of measuring biomedical data using an apparatus for measuring biomedical data, comprising:

  • inserting a measurement strip into the apparatus for measuring the biomedical data;

    applying blood to a reactive portion of the measurement strip on which enzyme material for measuring cholesterol is provided;

    detecting color change of the reactive portion of measurement strip in a predetermined period of measurement as a result of the biochemical reaction between the blood and the enzyme material on the reactive portion;

    determining reflectance of the reactive portion of the measurement strip in the predetermined period of measurement based on the color change;

    detecting a point of time at which a current average variation is a value which is equal to or less than a value obtained by multiplying the average variation of the dertermined reflectance in the predetermined period of measurement by a determination constant;

    determining reaction termination time according to the point of time;

    generating a correction value by calculating a difference between a measured value at a start of the predetermined period of measurement and a measured value at an end of the predetermined period of measurement;

    obtaining a final measured value by adding the correction value to a value of the reflectance measured at the determined reaction termination time; and

    converting the final measured value into the biomedical data.
