The Expanded Panel is also referred to as “Expanded Opiate” testing. It merely means that the most abused synthetic opiates (aka Opioids) are added to a standard 5 or 10 panel drug test.
“Opiates” normally refers to morphine, codeine and 6M-AM, the metabolite of heroin. The word “Opiate” is not really accurate when describing drugs like oxycodone, oxymorphone, hydromorphone and hydrocodone. We call them either “expanded opiates,” “extended opiates,”or just lump them together with codeine, morphine and heroin and refer to them as Opioids, as the US DOT did in 2018 when they expanded the federal drug panel.
“Opioid” is a term that also includes the commonly abused synthetic opiates, oxycodone, oxymorphone, hydromorphone and hydrocodone. More commonly, these drugs are known their trade names: OxyContin®, Percodan®, Percocet®, Vicodin®, Lortab®, Norco®, Dilaudid®, and Exalgo®.
