A standard 12 panel drug test kit is for the detection of marijuana, cocaine, opiates (heroin, morphine, opium, smack), amphetamine (Adderall, Dexedrine, speed, uppers), methamphetamine (crank, ice, crystal meth), benzodiazepines (xanax, valium), barbiturates, phencyclidine (PCP), ecstasy, oxycodone (Percocet, Percodan, OxyContin, Vicodin), methadone, and buprenorphine.
The twelve panel drug test is the most thorough drug test because it can test for extended opiates and the misuse of prescription painkillers like Percocet, Vicodin, and Lortab that would not show up on a test with fewer panels.
The hair follicle drug test can detect drugs up to the longest duration. Other drug tests include saliva and blood but urine is the most common because it is the easiest and the least expensive.
There are many reasons why you should take a drug test. Maybe your employer has a drug testing policy and could test you soon, or maybe you’re being considered for a job and a pre‐employment drug test is needed. They might also perform tests because an employee appears to be under the influence of drugs or alcohol on the job, if unexcused absence from work or lateness is an issue, or if performance appears to be impacted by drug or alcohol abuse. What ever the case may be you have to find out if you test positive.
