How Our Drug Test Panels Work

Our most common drug screening panels include street and prescription drugs known to be abused such as marijuana, cocaine, phencyclidine (PCP), amphetamines (including methamphetamine), and opiates. US Drug Test Centers can test for hundreds of other drugs such as tramadol, meperidine, ecstasy (MDMA/MDA/MDEA), fentanyl, and a long list of opioids such as oxycodone and hydrocodone - to name just a few. Employers most frequently conduct screening with our 5 panel drug tests, and our 8 panel drug tests being a common second choice.

US Drug Test Centers’ drug test panels are conducted by either a urine or hair specimen. Hair samples can be tested back as far as 90 days while a urine drug screening can go back as far as a week or longer, depending on the substance. US Drug Test Centers offers both lab-based testing as well as instant drug tests, though not all of our sites provide both services.

After being collected, our lab-based drug tests (or instant tests requiring laboratory confirmation testing) are sealed, packaged, and sent overnight to the closest national laboratory for further scientific analysis. The laboratory will conduct an initial ‘evidential’ test to determine the presence of drugs. If anything is found, the laboratory will perform a ‘confirmation’ test to determine what the substance is and the levels detected. Once testing is complete, the laboratory results are sent to a medical review officer (MRO). The MRO will review the results and conduct a donor interview, if appropriate, to determine if legal prescription drug use impacted the test results. Once satisfied, the MRO will make the results official and release to the donor or employer.

Why You Need a Drug Test Panel

As a long-accepted and scientifically proven, defensible and court admissible method to screen for drug abuse, drug testing has a wide variety of uses.

A large portion of drug tests conducted are for employment-related purposes. Employers rely heavily on employee drug testing because drug abuse in the workplace costs companies’ tens of billions of dollars every year and has a negative impact on workplace productivity, attendance, turnover rate, safety, and more. Combined with a comprehensive drug-free workplace policy, the right drug test panel can help keep your business safe, protected, and running efficiently.

Employers are cautioned to make sure they are aware of any state-specific laws that may limit the substances that they can screen for, how testing is conducted, and what instances drug testing can take place.

If your company must comply with the testing requirements of the Department of Transportation, US Drug Testing Center offers the products, services and testing panels to ensure you remain DOT-compliant, specifically with our DOT 5 panel urine tests and breath-alcohol testing.

Drug testing is conducted for many different reasons and applications, such as:

  • Employment purposes - Utilized in the workplace for pre-employment, random, reasonable suspicion, promotional, security clearance, post-accident, and return-to-duty instances.*
  • Federal testing - To comply with the Department of Transportation (DOT) regulations or other federal requirements.
  • Court-ordered drug testing - Testing as a condition of the court.
  • Probation - Testing as a condition of the court or probation officer.
  • Rehabilitation drug testing - Testing as a condition of a rehabilitation program or other Substance Abuse Professional (SAP) requirement to confirm the abstinence of drug use.
  • Child custody drug testing - Testing as a condition of child custody hearings.
  • Criminal cases - Testing as a condition of the court or law enforcement.
  • DUI or DWI arrests - Testing as a condition of the court or law enforcement.
  • Sports organizations – Institutional, semi-pro, private, collegiate, and professional athletes typically need to take a drug test for illegal drugs or substances that may be performance-enhancing.

*State-specific limitations apply, be sure to understand the rules and regulations in the state(s) that your company operates in.

Drug Facts

Marijuana [] - One of the most frequently used drugs of abuse in the United States. Found in its natural flower form as a green or brown leafy substance, but more commonly being found as oil, hash, wax, concentrate or edible. Marijuana contains delta-9-tetrahydrocannabinol (THC), the psychoactive ingredient that causes the ‘high’ for a user. Laboratories will look for CarboxyTHC which is a metabolite of THC.

Cocaine [] - A prevalent drug, known to be extremely addictive. A white powdery substance also found in ‘rock’ form, sometimes found laced with other illicit substances. Laboratories will look for Benzoylecgonine, which is the primary metabolite of cocaine.

Phencyclidine (PCP) [] -

[] - While initially used in veterinarian medicine (as a tranquilizer for horses), PCP became a drug of abuse and is still found in drug tests today. Found as a white powdery substance, but also in liquid form and often used with a cigarette or marijuana joint dipped in the substance. The drug is known to be very addictive and causes psychoactive, hallucinogenic, and euphoric side effects popularly giving users a ‘he-man’ level sense of strength.

Amphetamines [] - A popular prescription drug used for the treatment of attention-deficit hyperactivity disorder (ADHD). Commonly abused as a ‘study-aid’ for college students and adults or to ‘stay awake’ in specific demanding jobs such as long-haul truck drivers. Found in pill form.

Methamphetamines [] - An illegally altered version of prescription Amphetamine, this crystal-like substance is cooked with various over-the-counter drugs to create a highly-addictive, powerful, and potentially deadly drug.

Opiates (Heroin, Codeine & Morphine) [] - A drug derived from or related to the opium plant. Codeine and Morphine as prescription drugs. One of the most abused drugs gravely impacting every corner in our country is Heroin. Found in a white or brownish powder or black sticky substance that is often ‘cut’ with other drugs or substances. Injected, smoked or snorted, Heroin is highly addictive, euphoric, and a powerful drug is known to be very deadly as the leading cause of drug overdoses in the United States.

Expanded Opiates (Synthetic opioids including Oxycodone, Oxymorphone, Hydrocodone, and Hydromorphone) [] - Semi-synthetically produced opioids derived from the poppy plant and widely prescribed to treat pain. The leading cause of our nation’s opioid epidemic. Found in pill form, synthetic opioids are highly addictive, and when not used as prescribed, is known to cause severe liver damage, coma, or even death.

Methadone [] - Another synthetic opioid prescribed for use to relieve pain or to detoxify or recover from opioid addiction. Found in pill form, Methadone is also extremely addictive with a list of side effects.

Fentanyl [] - Yet another synthetic opioid prescribed for pain relief of cancer patients. The drug is 80-100 times more potent than morphine. Because of this, it has become a drug diverted for abuse. Originally designed as a patch that slowly releases doses of the drug, clandestinely produced Fentanyl is found as a white or brown powdery substance and often ‘cut’ with other drugs. The drug causes an intense, short-term high, is addictive and is one of the leading causes of drug overdoses.

Benzodiazepines [] - A commonly prescribed prescription drug depressant that induces sleep and provides relief from anxiety and seizures. Found in pill form, use of benzodiazepines come with a list of side effects, including death.

Barbiturates [] - Similar to Benzodiazepines, a prescription drug used to help sleep, relieve anxiety, and muscle spasms. Found in pill form with a list of side effects for the user, including death.

Ecstasy (MDMA/MDEA/MDA, known as 'Molly') [] -A trendy party or ‘rave’ drug. Found in powder or pill form (with a variety of logos and colors). Described as the ‘love drug’ can cause euphoria, empathy, and reduced inhibition.

ETG Alcohol Testing

Below is a chart for ETG Alcohol Testing Panels, for assistance with this content contact US Drug Test Centers

*What's the difference between alcohol and ETG testing? Alcohol testing detects the level of Ethanol present in urine at the time of testing. The average detection time frame for Ethanol is around 8-12 hours after consuming alcohol. EtG (Ethyl glucuronide) is a biomarker that can be detected in either hair or urine, up to 5 days after alcohol consumption.

4 Panel Drug Test

The 4 panel drug test screens for 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 their wide distribution. When abused, methamphetamines can be smoked, snorted, injected, or taken orally. Our opiate drug tests include both prescription drugs as well as illegal ones, like heroin and opium.

Drug testing for marijuana (THC) is especially important these days, given the legalization of marijuana and its many applications, both medicinally and recreationally. Employees who smoke on weekends or after business hours can easily show up to work the next business day impaired. How employees spend their personal time can have a significant impact on their work performance.

5 Panel Drug Test

The 5 panel drug test screens for marijuana, cocaine, phencyclidine (PCP), amphetamines, and opiates. This represents the standard 5 panel drug test used for Substance Abuse and Mental Health Services Administration (SAMHSA) certified laboratories.

When you order this drug test panel through US Drug Test Centers, you get the expanded amphetamines — which means we screen for methamphetamine, MDMA, MDA, and MDEA. Additionally, the opiate testing includes codeine, morphine, and heroin. Having a more expansive panel offers better (and more thorough) protection.

5 panel drug tests are the most common drug test panel in the United States and are available with a urine specimen or a hair specimen. Urine collection is the most common choice. 5 panel drug tests have been around since the 1980s when employee drug testing began in the United States.

5 Panel Drug Test Plus Expanded Opiates

The 5 panel drug test with expanded opiates screens for marijuana, cocaine, phencyclidine (PCP), amphetamines (including methamphetamine, MDMA, MDA, MDEA), and expanded opiates (including heroin, codeine, morphine, hydrocodone, hydromorphone, oxycodone, oxymorphone). It offers the same benefits of the traditional 5 panel drug test with the additional screening of opiates - a necessity, considering the current state of our country's opioid epidemic.

5 panel drug tests have been around since employee drug testing first started in the United States in the 1980s. It's the most common panel in the U.S. and can be done with both a urine specimen and hair specimen. Urine drug testing is more common, but hair drug testing offers a few unique benefits. For instance, it's more thorough and incredibly challenging to cheat.

6 Panel Drug Test

The 6 panel drug test screens for amphetamines, benzodiazepines, cocaine, marijuana, methamphetamines, and opiates. It is not very commonly offered by drug testing companies but is available when you order a drug test online through US Drug Test Centers.

Benzodiazepines are primarily used to treat anxiety, by working to reduce the activity level of nerves in the brain, and spinal cord — something that researchers believe contributes to anxiety. Individuals who abuse these drugs can find themselves becoming physically dependent on them. Furthermore, users often combine these drugs with opiates.

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

7 Panel Drug Test

The 7-panel drug test screens for amphetamines, cocaine, opiates, marijuana, phencyclidine (PCP), benzodiazepines, and barbiturates. It looks for these commonly abused substances in the individual’s urine sample. Drugs like cocaine and PCP are dangerous and highly addictive, presenting a severe threat to the workplace.

Barbiturates are central nervous system depressants that reduce the activity of your nerves and cause your muscles to relax. They also reduce your heart rate, slow your breathing, and lower your blood pressure. This class of drugs is particularly dangerous because even a minor overdose can lead to coma or death. They’re highly addictive, and the withdrawal process can be deadly.

The amount of the substance used, how they consumed it, the individual’s metabolism, their activity level, and other lifestyle habits help determine if the drug test results will come back positive or negative. Negative dilute drug test results can be retested if desired.

8 Panel Drug Test

The 8 panel drug test screens for amphetamines, cannabinoids, cocaine, opiates, phencyclidine (PC), barbiturates, benzodiazepines, and methaqualone in the individual’s urine specimen. This is typically an instant drug test that includes a review by a medical review officer for a non-negative result.

Methaqualone (Quaaludes) are hypnotic sedatives that are highly addictive. As the individual develops a tolerance, they will need more and more to achieve the same high, meaning they’ll eventually take dangerously high dosages. They were common club drugs and recreational drugs in the 1960s and 1970s but are no longer legally manufactured in this country.

Benzodiazepines, such as Xanax and Valium, are the most commonly prescribed depressant medications in the United States. Doctors often prescribe these to treat anxiety and sleeping troubles, but irresponsible usage can cause severe damage.

9 Panel Drug Test

The 9 panel drug test screens for marijuana, cocaine, phencyclidine (PCP), opiates, methamphetamine, methadone, amphetamines, barbiturates, and benzodiazepines.

The 9 panel drug test is typically used by employers to determine if a potential new hire is a safe and reliable addition to the company. Additionally, this screening is commonly used to test athletes for banned substances that may be artificially enhancing their sports performance and put them at an unfair advantage.

Methadone is a synthetic opioid often used to treat pain and narcotic drug addiction since it can help with tapering people off drugs. Because it’s similar to morphine but longer acting, medical professionals will sometimes use it as a substitute drug for treating morphine and heroin addiction. However, like an opioid, it can be addictive.

10 Panel Drug Test

The 10 panel drug test screens for amphetamines (including MAMP-methamphetamine, and 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 from this panel and provide only a 9 panel drug test, 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 are rarely available in the United States.

OxyContin is used to treat moderate to severe pain and is incredibly addictive, with a high that’s comparable to that of heroin. It’s one of the most frequently prescribed pain medications in the country, and the illegal sale of OxyContin has been a growing problem.

10 Panel Drug Test Plus Expanded Opiates

The 10 panel drug test with expanded opiates screens for marijuana, cocaine, phencyclidine (PCP), amphetamines (methamphetamines, MDMA, MDA, MDEA, ecstasy), benzodiazepines, barbiturates, methadone, propoxyphene, methaqualone or oxycodone, and expanded opiates (including heroin, codeine, morphine, hydrocodone, hydromorphone, and oxymorphone).

The 10 panel drug test is available with urine drug testing and instant urine drug testing.

There's one substance in the 10 panel drug test that can sometimes vary. Some labs have eliminated methaqualone from the panel and provide only a 9 panel drug test. In other cases, they have replaced the methaqualone with OxyContin® (oxycodone or OXY). The OXY add-on can make the panel more expensive. Methaqualone (also known as Quaaludes) is no longer legally manufactured and is rarely available in the United States.

11 Panel – Expanded Opiates

The 11 panel drug test screens for marijuana, cocaine, phencyclidine (PCP), amphetamines (methamphetamine, MDMA, MDA, MDEA), opiates (codeine, morphine, 6-AM/heroin), benzodiazepines, barbiturates, methadone, propoxyphene, methaqualone (Quaaludes), and expanded opiates, which include hydrocodone, hydromorphone, oxycodone, and oxymorphone.

Expanded opiate drugs are often called semi-synthetic and synthetic drugs. The expanded opiates panel is available using urine specimens, oral fluid specimens, and hair testing.

Employers use expanded opiate testing because of the widespread abuse of opiates. Oxycodone and hydrocodone, in particular, are being abused at an increasingly alarming rate. Regardless of the panel they’ve chosen, many employers are adding the expanded opiates to their drug testing program. This can help employers avoid the expensive cost of opioid abuse in the workplace.

A drug test positive for any expanded opiates will be verified to rule out any legitimate prescription drug use.

12 Panel Drug Test

The 12 panel drug test screens for cocaine, marijuana (THC, cannabinoids), phencyclidine (PCP, angel dust), amphetamines (including methamphetamines, also known as crystal meth), opiates (including heroin, codeine, morphine, hydrocodone, hydromorphone, and Oxycodone), propoxyphene, methadone, benzodiazepines (such as Xanax), barbiturates, meperidine, tramadol, and oxycodone.

When an individual is getting a hair drug test, the drug test specialist will cut a sample of hair from their head, as close to the scalp as possible in order to get the most recent growth. If there is no hair to take, they can use hair from the individual's arms and legs. The test is relatively quick and completely painless.

The hair sample is then sent to the lab to be screened for the specified substances.

13 Panel Drug Test

The 13 panel drug test screens for amphetamines, methamphetamines, oxycodone, barbiturates, propoxyphene, phencyclidine (PCP), tricyclic antidepressants, marijuana, cocaine, opiates, buprenorphine, and methadone.

Both buprenorphine and methadone are treatment drugs used for heroin and other opiate addictions, to help ease the symptoms of withdrawal. They can be used responsibly under the guidance of a physician, and if they are picked up on a 13 panel drug test, a medical review officer (MRO) will determine if the individual is safely using it with a doctor’s prescription.

However, buprenorphine is an opioid itself and thus carries a high risk for addiction and dependence. On its own, it commonly causes respiratory problems when abused and can be life-threatening. The risk is even higher if it’s combined with other substances, including alcohol.

14 Panel Drug Testing

The 14 panel drug test screens for amphetamines (methamphetamines), cannabinoids, cocaine, opiates (expanded opiates, including heroin, codeine, morphine, hydrocodone, hydromorphone, oxycodone, oxymorphone), phencyclidine (PCP), benzodiazepines, barbiturates, methadone, propoxyphene, oxycodone, meperidine, tramadol, fentanyl, and sufentanil.

Hair testing typically has a 90-day detection period starting at about 7 days after ingestion of the drug.

This is commonly called hair follicle testing, although interestingly, the hair follicle is not actually tested. The hair is cut as close to the scalp as possible, so the most recently grown hair can be tested for substances. It offers a few benefits over urine drug testing. For instance, it has a longer detection window, it’s harder to cheat, and it’s more thorough and accurate. For these reasons, hair drug testing results in twice the number of positive drug test results, compared to urine drug testing.

15 Panel Drug Test

The 15 panel drug test screens for phencyclidine (PCP), cocaine, LSD, marijuana, amphetamines, oxycodone, methamphetamines, barbiturates, phencyclidine, propoxyphene, benzodiazepines, buprenorphine, fentanyl, ketamine, methadone, methaqualone, and opiates. This is one of the more expansive drug test panels available.

Ketamine is a medication typically used for anesthesia since it causes a trance-like state, sedation, memory loss, and pain relief. However, it’s sometimes given to individuals outside of anesthesia to help with chronic pain. It has a history of abuse as a club drug.

The detection windows for all of these substances varies and is dependent upon a variety of factors – the type of substance, amount and frequency of use, body mass, age, the 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

The 16 panel drug test screens for cocaine, marijuana, phencyclidine (PCP), amphetamines, methamphetamines, opiates (including heroin, codeine, and morphine), barbiturates, benzodiazepines, meperidine, tramadol, MDMA, morphine, and synthetic THC.

Meperidine is of particular interest because the drug — used to treat moderate to severe pain — is typically injected by a doctor. Sometimes, an individual will be permitted to take it home to use under the guidance of a health professional. This is usually the only legal application of the substance.

Tramadol, an opioid pain medication, is concerning because although it can be used to treat moderate to severe pain, it’s 100% humanmade and carries a high risk for addiction and physical dependence. It can cause hallucinations, vomiting, fainting, rapid heart rate, and seizures and has recently been found to be more dangerous than initially anticipated.
