ABSTRACT

By far the most common investigation which brings patients to the attention of the haematology service is the full blood count. Abnormal parameters are flagged up by the automated counter and this may result in the generation of a blood film. The blood film is then interpreted in conjunction with the available clinical history, and in certain cases the reporting haematologist may contact the referring GP for a discussion on the telephone. The film report may give a definite diagnosis, or it may yield a differential diagnosis with suggestions for further appropriate investigations. Further, rapid referral of urgent cases to the appro­ priate consultant haematologist is usual because of the seamless nature of haematology care as a combined clinical and laboratory service. The film report and interpretation of less urgent cases is relayed to the GP, who is then faced with the problem of explaining the findings and the nature of any further investiga­ tions to the patient. In this chapter some details of these investigations will be outlined.
