In this study peripheral and marrow reticulocytes were counted by using the automated reticulocyte analyzer Sysmex R-3000 with the quick and accurate function of reticulocyte classification dependent on reticulocyte maturation. The correlation of reticulocyte count of the R-3000 to that of visual reticulocyte counting method was r = 0.926, y = 0.88x + 0.305 and r = 0.933, y = 1.32x + 0.328 for peripheral blood and bone marrow, respectively. The hematopoietic status of the bone marrow was reflected in peripheral reticulocytes better than in leukocytes or platelets. Moreover, at recovery stage from bone marrow suppression after chemotherapy, the ratio of immature type (HFR fraction) in peripheral reticulocytes increased to precede in several days increasing total reticulocytes. The relative reticulocyte counts in bone marrow was about 3 times higher than peripheral blood to be drawn at the same time higher and the patients suffering from megaloblastic anemia, MDS or DIC tended to have a much higher reticulocyte count in bone marrow than in peripheral blood.

Assessment of peripheral blood counts and blood film analysis are frequently performed as diagnostic procedures in emergency medicine. Far fewer situations exist, however, in which these analyses are the main clue in establishing an emergency diagnosis. Artifacts can lead to wrong diagnosis, e.g. pseudo-thrombocytopenia, which is defined as a low platelet count resulting from a laboratory artifact. Severe neutropenia (agranulocytosis) and extreme hyperleukocytosis, as well as suspicion of acute leukemia, require a rapid diagnostic work-up. A newly detected anemia should not necessarily be treated by packed red cell transfusions. The decision whether an anemic patient ought to receive transfusions should be based on the speed with which the anemia has developed, as well as on clinical judgement. As a rule a chronic anemia patient with hemoglobin above 70 g/l does not need transfusions. An uncritical transfusion policy can even cause emergencies, e.g. in patients with megaloblastic anemia or in anemic multiple myeloma patients with a hyperviscosity syndrome. An elevated hematocrit requires prompt further investigations. This is of utmost importance if one considers the diagnosis of polycythemia vera rubra, a disease in which patients are particularly prone to thrombotic complications. Fragmented red cells (schistocytes) on peripheral blood smears constitute a cardinal diagnostic clue for the detection of microangiopathic hemolytic anemias (MAHA), in particular for the diagnosis of the life-threatening thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). Malaria is another example for a chief role of blood smears examination in achieving a rapid diagnosis. If one encounters an unexpected severe thrombocytopenia, a marrow examination reveals whether it is due to rapid peripheral destruction, or due to a marrow failure. Furthermore, in any patients with an unanticipated thrombocytopenia, a disseminated intravascular coagulation and a MAHA should be ruled out. Heparin-induced thrombocytopenia is a rare, but possibly fatal complication of therapy with heparins.
