In stable, nonbleeding adults, what Hb threshold is commonly used as a red blood cell transfusion trigger?

Transfusion decisions in stable, nonbleeding adults aim to balance improving oxygen delivery with avoiding unnecessary risks from transfusions. The evidence supports a restrictive approach, using a hemoglobin threshold around 70 g/L (7 g/dL) as the trigger for transfusion. This default threshold reduces exposure to blood products without harming outcomes, as shown in major trials and reflected in common guidelines. Transfusing at higher levels (like 100 g/L) would lead to more transfusions without clear added benefit, while waiting until 50 g/L is typically too permissive for many stable patients. In some individuals with heart disease or notable symptoms from anemia, clinicians may individualize and consider a higher threshold, but 70 g/L is the standard starting point for routine cases.
