Many patients presenting in general practice will, at some time, complain of tiredness and lack of energy. Investigations to discover the cause are often conducted and will usually include blood tests such as a full blood count to see if anaemia is to blame. Patients may assume that all anaemia is iron deficiency anaemia but there are, of course, different types of anaemia. Interpreting investigations correctly and acting on them appropriately can ensure that the patient gets the right diagnosis and appropriate treatment.
