Vida works in the haematology laboratory of a small hospital. The laboratory’s haematology procedure manual contains instructions for staining blood smears and calls for applying the stain for 2 minutes and the buffer for 2 minutes. Vida stained three patient blood smears, but the smears appeared bluer than normal. When she examined the smears microscopically, the cells also appeared blue, making it difficult to identify them. 1. What can cause blood smears to stain too blue? 2. Discuss factors that could have affected the stain results.
