Was the testing through your State Lab or at a Vet's office? What does the report/analysis sheet say? Usually you get a report that says what they found in the organs and any tests results that were ran.
Marek's can be very complicated. Depending on the strain, you may lose quite a few or one her and there sporadically over time. It can be hard to know.
