The haematology team have reviewed our thrombocytopenic patient.  Heparin-induced thrombocytopenia is deemed unlikely as the HIT score is low and obstetric patients are low risk according to BCSH guidelines.

One concern is the diagnosis of Post-Transfusion Purpura.  This is is a rare complication of blood transfusion and typically occurs around a week post transfusion.

Questions:

• Why is PTP now rare?
• How is it managed?
• How do you confirm the diagnosis?
