[Diagnosis and therapy of anemia in general practice].

Anemia is a common problem in family medicine and therefore frequently investigated in general practice. Anemias are classified according to mean corpuscular volume (MCV) and reticulocyte count. An algorithm for the evaluation of the cause contains patients history and laboratory analysis including reticulocyte count, serum ferritin and CRP, serum vitamin B12, serum or erythrocyte folate and serum creatinine. Therewith most anemias in general practice can be explained. The most important types of anemia, e.g. iron deficiency anemia, are discussed as well as aspects of diagnosis and therapy. Iron deficiency anemia is often diagnosed together with other types of anemia, such as e.g. anemia of chronic disease. Particular aspects of anemia in the elderly as well as renal anemia are discussed.
