Full blood count (FBC)

Full Blood Count

A full blood count consists of haemoglobin, total white cell and differential counts, platelets and full red cell indices. All of these values are provided using a single EDTA sample. Please note that if venepuncture is difficult and mixing with anticoagulant delayed, micro-clot formation may cause a falsely low platelet count. If the full blood count results are abnormal or there is a specific indication on the request form, a blood film will be stained and examined microscopically.
