[Indication and value of erythrokinetic examinations in anemia].

As erythrokinetic studies are time consuming and costly, this technique should only be done to provide information which is unavailable through simpler tests. By means of discussion concerning the methodological procedure and obtainable information, the indications for erythrokinetic investigations with Cr 51 and Fe 59 are derived. Since the results should be interpreted together with the clinical and haematological findings, a close cooperation of the departments of nuclear medicine and haematology would be essential.
