The present invention includes a method and apparatus for the testing the integrity of a dialyzer prior to use. The dialyzer is tested on the same hardware used for the treatment of dialysis. The dialysate and blood sides of the dialyzer are primed in the normal manner. The blood and saline lines are clamped while the venous line is vented to the atmosphere. The ultrafiltrate flow rate is increased until the blood side fluid is ultrafiltered. The dialysate side is monitored for pressure increases. If the pressure does not increase, the test fails.

[ We claim:] [6.] A method for testing a dialyzer for leaks comprising the steps of: engaging with a dialysis patient a hemodialysis delivery system having a dialysis control unit with means to test a transmembrane pressure, a dialyzer having a dialysate compartment, a blood compartment and a membrane therebetween, a venous bloodline having a first and second end, and an arterial bloodline having a first and second end; performing hemodialysis treatment on said patient; testing the dialyzer in the hemodialysis delivery system; and performing hemodialysis on a second patient using the same hemodialysis delivery system if the dialyzer passes the test; and before said testing step, priming the dialysate compartment and blood compartment with saline solution, using saline lines.
