Collection Instructions:Collect sample before patient is given therapeutic iron or a blood transfusion. Blood transfusion can transiently increase in serum ferritin that peaks 24 hours post-transfusion, particularly if the blood has been stored for a longer period. (Blood 2011 Dec 15; 118(25):6675-82; Blood 1980 July;56(1):138-140).Therefore, if a patient has received blood, delay testing for several days to avoid false elevation of ferritin.
Causes for Rejection:Gross hemolysis; gross icterus
