Not only there are different types of test (like urine drug test, blood drug test, saliva, hair drug test), but also different variations of the same test. A simple urine test can be done with one of the following panels:
The NIDA 5-panel test
The NIDA panel test procedure is one of the most commonly used. In the collected urine sample five substances are tested: Cannabinoids, Cocaine, Amphetamines, Opiates and Phencyclidine (PCP). Immunoassays screen a urine sample to detect presence of metabolites, and if the test result is positive it is being sent out to be confirmed by MS/GC (mass spectrometry/gas chromatography).
The DOT 5- panel drug test
This test will check for Amphetamines, (including Methamphetamines), Cocaine, Cannabinoids (Marijuana/THC), Phencyclidine (PCP), and Opiates (Heroin, Codeine, Vidcodin, Morphine, Oxycodone, etc). These five substances are the most common drugs of abuse and are tested for in every test.
The DOT 10-panel drug test
This test includes five more substances that it tests for. Altogether it includes: Amphetamines (Crystal Meth), Methamphetamines, Benzodiazepines, Barbiturates, Methadone, Cocaine, Cannabinoids (Marijuana), Methaqualone, Phencyclidine (PCP), Opiates (Heroin, Codeine, Oxycodone, Morphine, Vidcodin). The laboratory test performs EMIT analysis, confirmation with GC/MS, and a testing review from an MRO (Medical Review Officer).
SAMHSA 5-panel test
The SAMHSA (Substance Abuse and Mental Health Services Administration) performs a screening for five substances, such as: Marijuana (THC), Cocaine (Benzoylecgonine), Opiates, Amphetamines or Methamphetamines and Phencyclidine (PCP). The presence of Opiates in urine samples would be triggered by Vicodin and Hydrocodone, Codeine, Hydromorphone or Dilaudid, Oxymorphones (Numorphan), Oxycodones, Percodan and Morphine. SAMHSA has its own guidelines pertaining to methods for drug testing.
Urine drug test is a reliable, inexpensive and most popular method of determining drug presence in a sample.
