Hemoglobin and thrombocytes are checked.
If poor effect of platelet transfusion, platelet value should be checked after approximately one hour. The value should have increased by approximately 30x10
9/l or more after a standard dose.

- Antigens against HLA or platelet-specific antigens. The patient must be examined in cooperation with the blood bank to find compatible donors.
