  1. Platelets contain a few red cells. Therefore a Rh negative baby receiving platelets from a Rh positive donor will need Anti-D 0.5ml (about 62ug) subcutaneously within 72 hours (usually straight away) after the platelets to prevent baby producing own Anti-D.
  2. The usual infections risk of blood transfusion apply also to platelets, e.g. HIV, HBV, HCV and NANB hepatitis, CMV, Syphilis, Malaria, etc or bacterial contamination of the products.


  1. Keep at Room Temperature: Mix well. Use platelets as soon as they arrive on ward.
