Many pathologists pursue a broad based training and become certified in both fields. These skills are complementary in many hospital based private practice settings, since the day to day work of many clinical laboratories only intermittently requires the attention of a physician. Thus, pathologists are able to spend much of their time evaluating anatomical pathology cases, while remaining available to cover any special issues which might arise in the clinical laboratories. Pathologists may pursue specialised fellowship training within one or more subspecialities of either anatomical or clinical pathology. Some of these subspecialities permit additional board certification, while others do not. Hence, this well-knitted; well-researched and well-debated work on this subject is highly academic and research quality will be appreciated and accepted by students; scholars and teachers.
