[Are hematologic reference values applicable to the healthy elderly?]
In the healthy elderly (65-90 years; 80 men, 75 women) the variability of haematological findings was examined and compared with the reference range. In the men, the ranges for haemoglobin valves (7.4-10.5 mmol/l) and erythrocyte counts (3.8-5.5 x 10(12)/l) proved to be lower than the reference intervals (8.5-10.9 mmol/l and 4.4-6.0 x 10(12)/l respectively). For the women no discrepancies were found. The question arises whether the reference limits for haemoglobin and erythrocytes should be lowered for elderly men.
