Fecal Occult Blood Testing
Welcome to Mayo Medical Laboratories' Hot Topics. These presentations provide short discussions of current topics and may be helpful to you in your practice.
Our presenters for this program are David A. Ahlquist, MD, Professor of Medicine and Consultant in Gastroenterology at Mayo Clinic in Rochester, Minnesota and Amy K. Saenger, PhD, Assistant Professor of Laboratory Medicine and Pathology and Director of Cardiovascular Laboratory Medicine in the Department of Laboratory Medicine and Pathology at Mayo Clinic in Rochester, Minnesota. Dr. Ahlquist and Dr. Saenger will describe a new approach to the detection of fecal occult blood. They will discuss the appropriate use of a new immunochemical assay and other fecal blood tests for current practice.
After viewing the Hot Topic, we invite you to participate in Beyond Hot Topic. This question and answer session will be posted online approximately 1 month after the Hot Topic presentation is posted. You can submit a question for Dr. Thorland or Karen at the end of the presentation. Alternatively, you can submit a question by selecting the Beyond Hot Topic link on the Hot Topic page. Thank you, Dr. Saenger and Dr. Ahlquist.
