1. Normal Erythrocyte count
   1. Indicates no problem with erythropoiesis
   2. Implies that LD's symptoms are not solely caused by a decrease in RBC's
   3. HOWEVER this does not rule out RBC's as a contributory factor
2. Low Haemoglobin count
   1. Suggests an abnormality in the morphology of the RBC
3. Raised Leukocyte count
   1. Possibly due to a bacterial or parasitic infection
4. High lymphocyte count from differential
   1. This suggests an immune response against 'foreign' material
   2. If these are T cells it would imply a cell mediated immune response
   3. Examples of T cell responses include various cancers and the H5N1 strain of the bird flu virus
   4. However a B cell response would indicate a humoral infection
5. Normal RBC count BUT low haemoglobin levels
   1. Microlytic anaemia
6. As we did not test for T and B lympocytes we cannot determine whether the high levels were caused by a cell mediated or humoral infection.
