10-panel drug test: Which drugs, timeframes, and results

A 10-panel drug test will look for 10 of the most common drugs that a person may be abusing. This selection usually includes five common prescription medications and five illicit street drugs.

Standard 10-panel drug tests normally test a person’s urine. This is a simple approach, as these drugs leave traces in the urine when they pass out of the body.

Urine testing is the most commonly used method due to its higher sensitivity in detecting substances than other forms of tests, such as saliva tests.

Some tests use other substances, such as blood or hair, to test for drugs. These may be more accurate in some cases, but the process is more complicated.

Many administrators prefer to use urine tests because of the accuracy and simplicity of the process.

As the name suggests, a 10-panel drug test will test the person for 10 different types of drugs. These are most of the drugs people commonly abuse, including both street and prescription drugs.

Cannabis

10-panel drug tests will test for cannabis and its resins, such as:

  • marijuana
  • hashish
  • extracts, including THC oil, wax, and glass

Cocaine

10-panel drug tests will also test for cocaine and other drugs containing cocaine, such as freebase or crack cocaine.

Opioids

Opioids come in many different forms, from prescription pills to illegal drugs. Some of the most common include:

Benzodiazepines, or benzos

10-panel drug tests will also check for benzodiazepines, or benzos, which include common drugs, such as:

  • diazepam (Valium)
  • alprazolam (Xanax)
  • lorazepam (Ativan)
  • clonazepam (Klonopin)

Doctors may prescribe these drugs for certain medical issues, but they also have a risk of abuse.

Amphetamines

Amphetamines the test detects include:

  • methamphetamine, or meth
  • amphetamine sulfate, or speed
  • attention deficit hyperactivity disorder (ADHD) medications, such as Vyvanse and Adderall

Barbiturates

Several barbiturates leave similar residues that the 10-panel drug test may pick up. These include:

  • amobarbital
  • phenobarbital
  • pentobarbital
  • secobarbital

Individual drugs

The test will also screen for the traces of individual drugs, including:

  • phencyclidine (PCP), or angel dust
  • MDMA (ecstasy)
  • methaqualone (Quaaludes)
  • propoxyphene

These drugs do not fit into other categories and have their own panel for testing.

While a 10-panel drug test may help screen for drug use, it has limitations.

Detection times refer to the amount of time it takes for the body to get rid of the drugs byproducts. Detection times for different drugs vary greatly.

Detection times may depend on the type of drug, how much the person takes, and how fast their metabolism works.

Another important fact to note is that a 10-panel drug test will not tell if the person is currently on the drug. The tests measure byproducts in the body that come from breaking down the drug, so they cannot detect how much of the drug is circulating in the body.

The following table provides a rough estimate for detection times for various drugs via urine tests:

DrugTime detectable in urinemarijuana3 days for a single use
5–7 days for moderate use (4 times per week)
10–15 days for daily use

3 weeks for long-acting (phenobarbital)benzodiazepines3 days for short acting (lorazepam)
1 month for long-acting (diazepam)PCP8 dayssynthetic cannabinoids72+ hours

10-panel drug tests are widely available online and from some specialist stores selling pharmaceutical equipment. Ordering a test through a doctor’s office or lab itself is the most direct way. However, there are also some kits a person can buy and send to the lab themselves. This latter option may be more tricky, however.

Most companies or doctors work directly with a lab that analyzes the test results. Getting the test done through them is a simple, direct approach.

If a company or organization requires a person to take a 10-panel drug test, they will generally give them notice of about 24 hours. Some professions may require the person to agree to random drug testing where they have little to no knowledge of the test beforehand.

The test administrators may have special preparation instructions as well. These may include not urinating for a couple of hours before the test or avoiding drinking extra water before the test.

Procedure

The test environment may differ depending on who administers the test. Bathrooms are common locations, as these tests require urine. In some cases, the administrator may ask a person to use a particular bathroom stall to take the test.

If an administrator is concerned with contamination, they may take precautions such as turning off tap water in the bathroom or adding a dye to the toilet water. This can make the test more accurate and prevent tampering.

In rare cases, a same-sex administrator stays in the room with the person to be sure they take the test.

Taking the test

The test itself is straightforward. The person starts urinating and collects urine in the collection cup in the middle of the urine stream. They then close the container with the lid and give the sample to the test administrator.

Analyzing the results

When they receive the sample, the lab will test the urine for the 10 different drugs. Some tests offer onsite results that can analyze the urine samples straightaway. However, most samples will go to a lab for analysis, which can take a few days.

A 10-panel drug test is not the most common drug test. For instance, most employers who require testing will use a 5-panel drug test. That said, some professions involving personal and public safety may require regular 10-panel drug tests.

10-panel drug tests can effectively test for 10 substances within their own detection window. These detection times vary with each drug and personal factors, such as individual metabolism.

Labs may check positive drug results again to confirm their diagnosis and avoid false positives. Inconclusive results may mean the person needs to repeat the test.
