No.  The membrane MWCO cannot be verified by the cassette integrity test.  The cassette integrity test cannot differentiate between a 10kD and 100kD membrane.  The membrane MWCO is verified by the solute passage test.  The membrane integrity test confirms if the cassette has been installed properly into the cassette holder, the torque has been applied sufficiently to activate the external seals, and there are no gross leaks on the membrane.
