What Does a 4-Panel Drug Test Test For?

Imagine you were offered a great job out of the blue that sets you up for amazing financial security and the stability you’ve been looking for.

But, just as you’re about to accept the job, the hiring manager drops a bombshell – a 4-panel drug test must be taken. So, what does the 4 panel drug test actually test for exactly? Let’s explore!


Exploring the Components of a 4 Panel Drug Test

A 4-panel drug test is used to test a person for the presence of certain drugs in their system. It screens for four of the most commonly abused drugs: cocaine, amphetamines, opiates, and marijuana. Depending on the circumstances, other substances, such as phencyclidine or barbiturates, can also be tested.

Generally, this drug testing method provides results for the presence of metabolites from these drugs in the urine, blood, saliva, or hair samples. In some cases, a mouth swab drug test is used for better accuracy.


Cocaine, in particular, is one of the more tightly controlled illicit substances and is classified as a Schedule II controlled substance in the US. This means that its use is restricted and only available for medical use by prescription. Cocaine use can have extreme risks to one’s health.

Physically, it can cause insomnia, increased heart rate and blood pressure, and death from overdose. Additionally, it can lead to mental health issues such as severe depression and anxiety. Cocaine use is not recommended and should be avoided.


Amphetamines are a stimulant drug that increases alertness, concentration, energy, and even self-confidence. There are both prescription and non-prescription amphetamines, the latter being illegal recreational drugs.

Those without a prescription may be found in speed, ice, crank, or crystal meth.


For opiates, the drug test looks for morphine, the key metabolite in heroin, and codeine. Codeine is an opioid that is often found in some prescription pain relievers as well as cough syrups.

Morphine is found naturally in poppies and, in modern medicine, is used to treat moderate to severe pain. 


The THC component of the test detects the presence of the psychoactive ingredient in marijuana, known as tetrahydrocannabinol (THC). A urine sample is typically taken for the drug test and, if it is present, will cause a positive result.

The test is designed to detect the presence of THC metabolite in the sample, which has an average detection time of 3 to 4 days.

Accuracy and Reliability of 4 Panel Drug Tests

This type of drug test offers high accuracy and reliability, as it has a high rate of detecting positive drug use results. Many employers use the test to ensure that their employees are not abusing drugs while on the job.

It can also be used to detect drug use before any legal proceedings.
