After the patient is determined anemic and the history and physical exam is complete, several simple tests can be performed which may quickly point to the general cause of the anemia. Most if not all of these tests will be available in field the hospital or on board ship. By carefully following these recommendations, a correct diagnosis can often be determined and an appropriate treatment can be prescribed. Anemias Most anemias can be classified into three broad categories. All of these conditions cause a decreased erythroid activity within the marrow.
Treatment depends upon the primary cause.
Reviewing the RBC indices often makes diagnosis. B12, iron, and folate levels can be easily measured. If low, treatment is generally straightforward. This rapid production of RBCs is most often reflected as a markedly elevated reticulocyte count. This is a relatively quick way to determine if your patient has suggestive evidence of ongoing hemolysis.
