The possibilities of modern automated clinical blood analysis in differentiated diagnostic of true and redistributing (functional) iron deficiency under anemic syndrome in oncologic patients
The clinical blood analysis implemented at modern hematological analyzers can be used as a foundation for primary differentiated diagnostic of anemic syndrome related to true and functional iron deficiency in oncologic patients. The normocyte normochromic anemia with normal and higher level of hemoglobin of reticulocytes (RET-HE) testifies presence in higher degree of anemia of chronic diseases which is more often combined with higher content of serum ferritin (Ferr), lower level of soluble receptors of ferritin (sTfR) and production of erythropoietin (EPO) inadequate to anemia degree. The microcyte hypochromic anemia can be present both under iron-deficient anemia and under functional iron deficiency as a result of its blocking in macrophages under anemia of chronic diseases in oncologic patients. Hence the differentiated diagnostic of these states demands additional analysis of content of serum ferritin, soluble receptors of ferritin and production of erythropoietin.
