[Experiences with intranasal and parenteral use of 1-desamino-8-D-arginine vasopressin (DDAVP). Use in a simple test of renal concentrating ability].

The possibility of the use of 1-desamino-8-arginine-vasopressin (DDAVP) in a functional test of the renal concentration ability was controlled. In accordance with the data in literature the results allow to propose the DDAVP concentration test as screening method for this renal function. Essential advantages are the short duration and the small laboratory-technical expenditure. A standardized approach including propositions for a critical valuation of the results is represented and its control in patients is described. If the results should be confirmed by a control in other institutions, the test might be recommended for practice.
