Moreover, the panel may embrace exams for artificial opioids like fentanyl, in addition to different substances relying on the precise necessities of the testing entity.
1. Substance Identification
Substance identification is the cornerstone of any complete drug screening, notably the 14-panel drug take a look at. This facet defines exactly which substances the take a look at is designed to detect, forming the idea for its utility and relevance. Correct substance identification ensures the take a look at’s efficacy in assembly particular wants and regulatory necessities.
-
Illicit Drug Detection
A main perform of the 14-panel take a look at is to establish the presence of generally abused illicit medication. This contains substances corresponding to cocaine, marijuana (THC), amphetamines, methamphetamine, opiates (heroin, morphine, codeine), and phencyclidine (PCP). Detection depends on figuring out the mother or father drug or its metabolites current within the urine pattern. As an illustration, the presence of benzoylecgonine signifies cocaine use, whereas carboxy-THC signifies marijuana consumption. The accuracy of figuring out these substances is essential in authorized and employment contexts the place drug use is prohibited.
-
Prescription Drug Monitoring
The 14-panel take a look at additionally incessantly screens for prescription medicines with potential for abuse. This usually contains benzodiazepines (like diazepam and alprazolam), barbiturates (like phenobarbital), and opioids (like oxycodone and hydrocodone).
