Could u expect reliable results in enzyme assay performed on tissue sample removed from autopsy and why?

Question

what type of errors might result in such postmortem studies?how might we determine more clearly the possibility that a patient had suffered a myocardial infarction in biochemical terms?

Answer 1

It may be difficult to extract enough uncoagulated serum to get a test for troponin levels. If it was massive infarction, you may be able to see loss of perfusion in cardiac muscle histologically. Low temperatures would decrease enzyme degradation.

If you already knew this, sorry.
