Drug Test Panels

US Drug Test Centers offers many different types of drug and alcohol testing panels. We have hundreds of drugs and illicit substances we can test for. Our most common panels include marijuana, cocaine, PCP, amphetamines and opiates but we also can test for drug such as fentanyl, tramadol and merperdine to name just a few. These drug test panels are tested by either a urine or hair sample. Hair samples can be tested back as far as 90 days while urine samples can go back as far as a week ago. US Drug Test Centers offers both lab-based testing as well as instant tests, though not all of our sites offer both services.

Whether you are looking to send an employee for a pre-employment test or you have to perform a court-ordered test, we would be glad to help you out. Our SAMHSA certified labs will follow proper procedures to ensure that all of our tests are valid. We also offer services to ensure that you are in compliance with the Department of Transportation, specifically DOT 5 panel urine tests, and breath-alcohol testing.

US Drug Test Centers can perform testing at our 20,000 locations with results reported in a quick and timely manner. We try to make ordering a test quick and easy by allowing you to order your tests online or by calling one of our drug test specialists at 866-566-0261.

4 Panel Drug Test

Substances included in the four panel drug test include THC (marijuana), cocaine, opiates, and methamphetamine. Typically this test is performed in a testing facility and is an instant-read test.

The drugs in this panel are some of the most commonly abused street drugs. They are seemingly the most accessible to addicts because of the wide distribution. When abused, methamphetamines can be smoked, snorted, injected or taken orally.

5 Panel Drug Test

The 5 panel drug test is the most common drug test panel in the United States and is available with a urine specimen, or a hair specimen. Urine collection is the most common choice. 5 panel drug testing has been around since the 1980’s when workplace drug testing began in the United States. Our 5 Panel most common drug test tests for marijuana, cocaine, PCP, amphetamines and opiates.

6 Panel Drug Test

This screening tests for amphetamines, benzodiazepines, cocaine, marijuana, methamphetamines, and opiates. It is not very common, but exists.

Drug tests, when you boil it down are used to detect the use and abuse of illegal and illicit substances in everyone from prospective employees, professional and semi-professional athletes, court ordered persons, participants of drug rehabilitation programs and more.

7 Panel Drug Test

The 7-panel urine drug test looks for commonly abused substances in a urine sample. Depending on the amount used, metabolism, and habits of the person will determine if the test is positive or negative. Substances tested include amphetamines, cocaine, opiates, marijuana, phencyclidine (PCP), benzodiazepines, and barbiturates.

8 Panel Drug Test

The 8-panel urine drug test commonly screens for amphetamines, cannabinoids, cocaine, opiates, phencyclidine, barbiturates, benzodiazepines, and methaqualone. This is typically an instant test that includes a review by a medical review officer for a non-negative result.

9 Panel Drug Test

A 9-panel drug test is used to evaluate and test for the presence of various substances in the body. This is typically used by employers to determine if a potential new hire will fit in their current role; this screening is additionally used to test athletes. The panels referenced are marijuana, cocaine, PCP, opiates, methamphetamine, methadone, amphetamines, barbiturates, and benzodiazepines.

10 Panel Drug Test

The 10 panel drug test includes amphetamines (including MAMP-methamphetamine, MDMA-Ecstasy); cocaine, opiates (including codeine, morphine and heroin); Phencyclidine (PCP); marijuana (THC); benzodiazepines, barbiturates; methadone; propoxyphene; and methaqualone (Quaaludes).

Some labs have eliminated the methaqualone and provide only a nine panel and some have replaced the methaqualone with OxyContin® (oxycodone or OXY). The OXY add on can make the panel more expensive. Methaqualone/Quaaludes are no longer legally manufactured and rarely available in the United States.

11 Panel – Expanded Opiates

Expanded opiate drugs are often called semi-synthetic and synthetic drugs or opiates. The expanded opiates panel is available for drug testing in urine specimens, oral fluid specimens and hair testing. Urine tests can detect synthetic opiates for 2-4 days, and hair tests are effective for 90 days.

Many employers are looking at the expanded opiate testing because of the widespread abuse of opiates. A drug test positive for any drug including expanded opiates will go to the medical review officer (MRO) for review and verification to rule out any legitimate prescriptions for these drugs.

13 Panel Drug Test

This multi panel drug screen includes a screen for buprenorphine and methadone, both treatment drugs used for heroin and other opiate addictions. Popular illegal drugs like marijuana, cocaine and opiates are also tested in the 13 panel drug test. Other drugs included in this test include amphetamines, methamphetamines, oxycodone, barbiturates, propoxyphene, phencyclidine, and tricyclic antidepressants.

14 Panel Hair Drug Testing

The 14 panel hair drug testing is a comprehensive look back for an extensive list of drugs of abuse. Hair testing typically has a 90 day look back period starting at about 7 days after ingestion of the drug. It is interesting that although this is commonly called hair follicle testing, the hair follicle is not actually tested. The hair is cut as close to the scalp as possible so the most recently grown hair is tested.

15 Panel Drug Test

This 15 screening includes popular illegal substances such as PCP, cocaine, LSD, and marijuana. Other substances included are amphetamines, oxycodone, methamphetamines, barbiturates, phencyclidine, propoxyphene, benzodiazepines, buprenorphine, fentanyl, ketamine, methadone, methaqualone, and opiates. The detection windows for these substances varies and is dependent upon a variety of factors – type of substance, amount and frequency of use, body mass, age, overall health of the donor, and pH of the sample. The average timeframe of a urine screening is for the last one to five days of use.

16 Panel Drug Test

16 Panel Drug Screens can be used to discover abuse of the most commonly abused substances. Substances included include cocaine, marijuana, phencyclidine, amphetamines, methamphetamines, opiates including heroin, codeine, and morphine; meperidine, barbiturates, benzodiazepines, meperidine, tramadol, MDMA, morphine, and synthetic THC.
