The routines for blood testing were changed during 2010 at the blood bank in UAS. At first, the blood test was taken before the donation and now it is taken after donation. Along with this, the blood bank increased the lowest level for allowance of blood donation with 10 g/L both for men and women. The level is now on 125 g/L and 135 g/L for women respectively men. After the increase, it was noticed that the amount of blood donors were deferred due to low Hb levels in creased. A study made in year 2013, investigated how much the Hb-levels actually was changed during a blood donation. It showed that it was lowered in means by 6 g/L and not 10 g/L as previously thought.The aim of this study was to see if the sitting position of the blood donor during waiting time and the supine position during the time of blood donation may had any effect on the difference of the Hb-level during the blood donation.Data from the 120 blood donors in the earlier study was collected. Hb values, before and after blood donation, were taken from the earlier study and registered times were taken from the database Prosang. The waiting time, time of blood donation and the difference of Hb-levels were calculated and correlated with Spearmanns correlation coefficient.The results did not show any correlation between the times and the difference in Hb-levels. One of the reasons may be that the blood donor physiology differ and thus the change in Hb-level can vary.
