A donation interval of 4 months is appropriate in terms of RBC recovery, but may not be appropriate in terms of iron store regeneration. The tendency to shorten the donation interval should be reconsidered in light of the measurements of iron storage. The use of ferritin levels is recommended as a preselection criterion for allogeneic 2-unit RBC apheresis.

The glaucoma program Gl is widely employed by Octopus users. In addition to a specific distribution of test locations, its main advantages are the quick comparison of results with normal values and an easy follow-up. The program, however, is relatively time consuming and, therefore, tiring for some patients. For this reason, the program was modified to ‘G1X’. This program is interruptable at any time and provides information, including statistical analysis based on the available data. The test sequence is rearranged in accordance with the importance of the information. The available information, including the confidence limits, is continuously calculated and presented on the screen of the Octopus 1-2-3 during the test procedure. This provides the possibility of adapting the measurement to the patients and their state of health. The principal features as well as clinical applications are described.
