Course provided by LabCE.

The goal of this continuing education course is to provide essential knowledge to histology professionals regarding the structure and function of a liver biopsy received in the pathology laboratory. This course explores common diseases and provides information regarding how a liver biopsy assists the pathologist and clinician in diagnosing these diseases. Upon completion of this course, the histotechnologist will have a greater understanding of optimal histotechniques used to create slides that are adequate for diagnosis, develop a foundational knowledge about the anatomy of a liver biopsy (as well as common diseases), and also identify artifacts, special stains, and pigments that are specific to liver biopsies that may be used to assist in diagnosis.

Author information: Brooke Eguia, BS, MS, HT(ASCP), HTL(ASCP) is the Pathology Technical Supervisor at Fairview Southdale Hospital in Edina, Minnesota. She graduated from St. Cloud State University with a Bachelor of Science degree in general biology and from Capella University with a Master of Science in Human Service with a specialization in Health Care Administration. During her time as an undergraduate, Brooke's interests and studies focused on histologic techniques and gross anatomic dissection. Her senior year, she co-authored for aquatic toxicology research that Aquaculture published in January 2009. Acting as a primary health career mentor to high school students, Brooke satisfied her desire for training and teaching histotechnicians and also worked as adjunct faculty at Rasmussen College, as a Medical Assistant laboratory techniques instructor. Most recently, she has focused on proctoring histology students in clinical/classroom progress and exam preparation.
