Hire a Certified Pathologists' Assistant
Pathologists assistants (PAs) can provide labs with a much-needed, cost-effective way to reduce pathologists workloads, both in surgical and autopsy pathology. PAs are trained to assume the grossing, autopsy dissection, and teaching responsibilities previously provided by pathologists, as well as provide administrative support for the pathology department as a whole.
Eligible for certification by the ASCP Board of Certification, PAs have met the highest standards for education and training in the profession of pathology, ensuring that your pathology laboratory is meeting the standards of not only your licensing bodies (CAP, CLIA, Joint Commission), but your pathologists and surgeons as well.

(1) Our website was invaded by malware for an hour last Friday. Although this was quickly fixed, we want to share some lessons we learned. First, to protect any important online accounts, you should use a strong password of 8 or more digits, upper and lower case characters, and change it frequently. Unfortunately, people using automated methods are trying to guess passwords for their own purposes. Second, if a website asks you to open a file at a random moment, that may be malware - don't do it. Third, review your own security regularly, and consider anti-virus / anti-malware programs, even with a Mac. If you have any concerns about our website or about security in general, email or call us and we will respond as soon as possible.
(2) We are constantly looking for new Reviewers for our 7,000 topics, which we want to update every 1-2 years. Visit our newly updated Author Instructions page for more information.
(3) The Table of Contents of our Stains chapter now includes all 360 stains / biomarkers described in the chapter. The CD Markers chapter contains an additional 260 markers. We update these pages regularly, but let us know of any new markers we should include or other changes we should make.
