The gold standard for COVID-19 detection in FFPE samples remains the qRT-PCR as in swab samples, contextually other methods have been developed, including immunohistochemistry (IHC), and in situ hybridization (ISH). In this manuscript, we summarize the main data regarding the methods of COVID-19 detection in pulmonary and extra-pulmonary post-mortem samples, and especially the sensitivity and specificity of these assays will be discussed.engopenAccessCOVID-19immunohistochemistryin situ hybridizationautopsy samplessars-cov-2autopsypcrarticleCopyright PACINI EDITORE10.32074/1591-951X-933Pathology1591-951X
