Abstract: A peritoneal function testing method of using a ratio MTACun/MTACc calculated using MTACun and MTACc as an index for a peritoneal function test. MTACun is an overall mass transfer-area coefficient for urea nitrogen and MTACc is an overall mass transfer-area coefficient for creatinine. Use of the MTACun/MTACc ratio enables examination of the future peritoneal function of a patient (a mechanism of deterioration in peritoneal function). MTACun and MTACc are obtained using a Pyle-Popovich model. The peritoneal function testing method further calculates a permeability coefficient for cell pores (LPSC) and an overall permeability coefficient (LPS) from a Three-Pore Theory model to obtain a ratio LPSC/LPS calculated using the LPSC and the LPS, and further uses the LPSC/LPS ratio and the MTACun/MTACc ratio as indexes for the peritoneal function test.
