A test method determines at least one status parameter of an individual undergoing peritoneal dialysis. The status parameter(s) may include a transport property of the peritoneum, a tonicity, or a residual volume. The test method includes receiving first data indicative of a flow rate as a function of time of a treatment fluid into and out of a peritoneal cavity during a test procedure, and second data comprising measured data samples representing a concentration of one or more solutes in the treatment fluid at time points during the test procedure. The test method also includes computing, based on the first data and by use of a transport model for a peritoneal membrane, estimated data samples representing the concentration of the one or more solutes in the treatment fluid at the time points and determining the status parameter(s) as a function of the measured data samples and the estimated data samples.
