Why do the forensic toxicology tests take so long?
Getting a complete and accurate forensic toxicology test result can be a lengthy process for a variety of reasons, according to the College of American Pathologists and experts interviewed by WebMD. There may be a lot of specimens that need to be tested, which means more testing time. And as an investigation proceeds, information about the possibility of another drug being involved may surface, so even more testing may be needed. When the first round of positive tests have to be confirmed by the more sophisticated method, this may require sending out the specimens to more specialized laboratories. And that adds to the delay. “Four to six weeks is pretty standard,” Magnani says of the time line for forensic toxicology testing. Besides the time needed for painstaking analysis and confirmation, she says, there could be a backlog of tests that need to be done at a particular laboratory. “Each one should be handled thoroughly, whether they are a celebrity or not,” she says.
