The Impact of Red Packed Cells Transfusion on the Main Biological Markers to Determine the Etiology of Anemias

The aim of this work is to study the changes of key assays useful for the understanding of anemia mechanism before and after red packed cells transfusion: iron status, vitamin assays, hemolysis markers.

The patient selection criteria are:

• age > or = 18 years
• No history of transfusion > or = 2 years
• Anemia (any etiology known or assumed)
• Decision of red packed cells transfusion for the current episode
• Transfusion performed at BEAUJON Hospital
• Agreement of patient for the study

Number of subjects required: 100 patients

Study duration and duration of participation for each patient:
