[Recommended algorithms of prescription in the diagnosis of iron deficiency and overload].

In view of the recent development of new tests of biochemistry and molecular biology the assessment of iron status should be reconsidered and updated. The French Society of Clinical Biology (SFBC) and the French Society of Hematology (Cellular Hematology Group) recommend algorithms in the diagnosis of iron deficiency and iron overload bearing in mind the best efficiency and health economy. These recommendations are based on the known sensibility and specificity of each test. The analytical requirements for the determination of the tests as well as the clinical and biological signs evoking an iron deficiency or overload are recalled.
