Haemoglobin/platelet level for transfusion

Posted by

Hello Caroline

Another question, not sure if it is too specific. Is there a standard threshold level of platelets/haemoglobin when they advise having a transfusion. I was told it was 20 for platelets, but I'm not sure if that is patient specific or depends on illness. I have relapsed AML. Two weeks ago I had HB of 93 and told no transfusion. A week later at 85 I had one unit, as non-urgent 3 days later. Last test Friday I was 93 again but nurse thought I would need transfusion on Monday. 

Thanks, Tessa

Hi Tessa, 

Generally platelets are given  if they are below 20, some units below 10 or if bleeding.

Again generally we give blood if Hb is below 90, or if patient is symptomatic. Every patients tolerance is different though and rather than Hb going up and down like a yo yo, I prefer to anticipate a drop and give blood to prevent this.
