[Reference values of clinical donor blood analysis].

Basic hemogram parameters were analyzed in 835 blood donors (421 men and 414 women) aged 18 to 67 years) on an ADVIA 120 hematology analyzer. Reference ranges were calculated for each parameter in relation to their distribution (as X mean +/- 2alpha for normally distributed data and 2.5-97.5 per thousand for others). The findings suggest that the normal range should be extended for platelets, red blood cells, hemoglobin, and packed cell volume as compared with the earlier unified normal values, which must be taken into account when deciding whether a subject may be allowed to donate blood.
