Sample validity for platelet transfusion

Recommended Posts

Hi All

If patient has 2 known historical blood group, do we still need valid group and save at time of platelet transfusion? I am trying to find out in guidelines but unable to find.  If patient is on regular platelet transfusion how often should we repeat group and save  and why?

Here we have to positively ID a patient for each admission.  This involves arm banding and at least an ABO/Rh for plasma or platelets.

Not in the UK gagpinks.  The chances of someone else needing platelets of an identical name, hospital number and date of birth are remote, as to be disappearingly likely, and, in any case, the amount of plasma involved is not likely to cause a transfusion reaction in an adult.  Lastly, if they needed HLA-matched platelets, at worst, the platelets would not last too long in the circulation, but would not cause a reaction.

Thanks Malcolm 

I just wanted be assured. 

Our SOP suggest it is good laboratory  practice to get new sample after 2 units of platelet transfusions  however i don't see any benifits if patient need regular platelet transfusions especially haem patients

Except, as been noted here on various threads over the years, it can happen that a patient becomes admitted under someone else's identity.

Also, I am pretty sure that our inspectors over here would also have a problem with D+ platelets being given to a child-bearing-age female who was actually D-!

Oh yes, we would give anti-D immunoglobulin in such a case, but, if it were a case of identity theft, and the recipient made allo-anti-D, and it went to court, the thief would not win!
