A component such as cholesterol contained in a specific lipoprotein fraction in a biological sample is quantitatively analyzed by agglutinating the specific lipoprotein fraction, leading a component, which is contained in lipoprotein fractions other than the specific lipoprotein fraction and is the same as the component to be analyzed, to a different reaction system which does not take part in the quantitative analysis; dissolving the once agglutinated specific lipoprotein fraction, subjecting the specific lipoprotein fraction to a quantitative reaction, and measuring a degree of a change caused by the quantitative reaction to determine an amount of the component in the specific lipoprotein fraction. |
