ABSTRACT OF THE DISCLOSURE Disclosed is an acetyltransferase activity measuring agent which contains an arylamine derivative. As the arylamine derivative, sodium p-aminohippurate can be used preferably. Use of the acetyltransferase activity measuring agent of this invention permits a simple and safe diagnosis of the progress of the pathema of nephritis, which is accompanied by a mesangial proliferative lesion, or renal insufficiency. Furthermore, the scattering of measured values is small, thereby assuring an accurate diagnosis. |
