Abstract: The present invention provides a method comprising a step of estimating the kidney function of an arbitrary subject by a regression analysis which employs the amount of a D, L-amino acid in a biological sample from the arbitrary subject as an explanatory variable and employs the amount of filtrated glomeruli in the arbitrary subject as an object variable, by employing a previously determined formula (I): Y=a1·X1+a2·X2+ . . . +an·Xn+b (I) [wherein a1 to an independently represent a constant obtained by the regression analysis; X1 to Xn independently represent a variable of the amount of the D,L-amino acid which is selected by the regression analysis; and b represents a constant obtained by the regression analysis] on the basis of the Y value calculated from the amount of the D, L-amino acid in the biological sample from the object to be evaluated. Also provided is a system for carrying out the method.

Abstract: The present invention provides a method for determining glomerular filtration ability on the basis of the amount of D-serine in the blood. The present invention provides a blood analysis system which includes a storage unit, an analysis measurement unit, a data processing unit and a glomerular filtration ability output unit, wherein: the storage unit stores the correlation equation between the amount of D-serine in the blood and glomerular filtration ability; the analysis measurement unit separates and quantifies the amount of D-serine in the blood; the data processing unit calculates glomerular filtration ability by inputting the D-serine amount into the correlation equation stored in the storage unit; and a pathology information output unit outputs glomerular filtration ability information.

Abstract: The purpose of the present invention is to provide: a method for predicting the prognosis for kidney disease for a subject on the basis of the amount of D- and L-amino acids, from a blood sample; and an analysis system that determines prognosis predictions. This purpose is achieved by using at least one amino acid to predict the prognosis for kidney disease, said amino acid being selected from the group consisting of D-serine, D-asparagine, D-proline, D-alanine, D-leucine, D-lysine, D-allo-isoleucine, L-glutamic acid, L-alanine, L-tryptophan, and L-asparagine.
