Cellular pathologists (Histopathogists, Cytopathologists) are medical doctors who have specialised in cellular pathology. They have attained their primary medical degree after completing the usual five or six years of medical school. They have thereafter performed at least two year, usually more, of clinical practice involving a mixture of medical jobs including emergency, surgery, paediatrics and general medicine. They then apply for a training position to study whilst working in the field of cellular pathology, during which time they are called a registrar. In the UK this is a 5 year full-time programme in which the registrar is required to work in a number of different laboratories to get the required experience necessary to work as a consultant (fully qualified) cellular pathologist. Two professional examinations must be sat, one in the 3rd and the other in the 4th or 5th year of training. Training and registration of all pathologists, including cellular pathologists, in the UK is overseen by the Royal College of Pathologists (RCPath).
