Ferritin is the intracellular storage form of iron, found chiefly in the cytoplasm of the cells of
the reticuloendothelial system. 1 By means of immunoradiometric assays it can be …

CMA JOURNAL/JUNE 21, 1980/VOL. 122 1355 with iron deficiency the serum ferritin
concentration was not reliable for making the diagnosis. These results agree with those of …

Measurements of serum ferritin were correlated with other hematologic laboratory indexes in
250 hospitalized subjects with anemia or disorders in iron metabolism. A geometric mean …

The efficacy of measuring the transferrin saturation and the serum ferritin concentration to
detect iron deficiency was determined under routine conditions in a general hospital. The …

In healthy persons the plasma ferritin concentration is a sensitive index of the size of body
iron stores. It has been successfully applied to large-scale surveys of the iron status of …

We examined the relationship of serum ferritin to bone marrow iron stores in 73 anemic male
medical inpatients with liver disease, alcoholism, chronic inflammatory disease, and …

Sir, In our opinion, the above study'was flawed by the implied assumption that all serum
ferritin levels below 50 lg/l were equally valid for the diagnosis of iron deficiency. In …

While the prevalence of iron deficiency has remained relatively constant, there has been
continuing refinement in its laboratory recognition, especially with the recent introduction of …

Determination of serum ferritin is an important means of assessing body iron stores. Trace
