Kt/V. In medicine, Kt/V is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy. In the context of hemodialysis, Kt/V is a pseudo-dimensionless number; it is dependent on the pre- and post-dialysis concentration (see below). It is not the product of K and t divided by V, as would be the case in a true dimensionless number. In peritoneal dialysis, it isn't dimensionless at all.
