AMP Case Reports in CAP Today

AMP Seeking Case Reports for Potential Publication in CAP Today

Do you have a compelling molecular case that you wish to share with a broad audience of laboratory professionals? AMP's Publications Committee is seeking submissions from all AMP subdivisions for potential publication in CAP Today. This is a great opportunity to share your expertise and be of service to AMP! Please submit cases by May 31. The corresponding author must be a current AMP member.

The AMP Case Reports for CAP TODAY are intended to help pathologists who are not yet especially familiar with molecular pathology to understand the power and appropriate use of molecular tests. The teaching strategy will be to take them from what they do know, e.g., special stains, to new knowledge in molecular pathology.
