How long does it usually take for an autopsy report to be completed?

This often depends on the number and complexity of tests that need to be performed on bodily fluid and tissue samples taken at autopsy. Toxicology tests, microscopic analysis, and DNA testing could take weeks or even months to complete, especially if re-testing is needed. Usually, one can expect testing to take at least twelve weeks to get the results and then it can be expected for autopsy reports to be finalized soon thereafter unless there are other factors involved that cause delay.
