What is a Pre-Employment Drug Test?

People often refer to a drug test for employment as a pre-employment drug test.

What is a Pre-Employment Drug Test

It is a screening process conducted by employers during the hiring process to determine whether prospective employees are using drugs or substances that could affect their job performance or workplace safety. Here’s an overview of what a drug test for employment entails:


The primary purpose of a drug test for employment is to ensure that job candidates are not using illegal drugs. Also, check the abusing prescription medications that could impair their ability to perform their duties safely and effectively. Employers want to create a safe and productive work environment.


Usually, employers conduct a pre-employment drug test after extending a job offer but before the candidate officially starts the job. In some cases, it may be a condition of the job offer.

Types of Tests:

Employers can use various types of drug tests, including urine tests, saliva tests, hair follicle tests, and blood tests. The choice of test method depends on factors such as the employer’s policies, industry regulations, and the level of invasiveness deemed appropriate.

Drug Panels:

The specific drugs and substances screened for can vary depending on the employer’s drug testing policy. So, common drug panels include the 5-panel and 7-panel tests, which test for different categories of drugs, including marijuana, cocaine, amphetamines, opioids, and more.


During a pre-employment drug test, the candidate typically provides a sample, such as a urine sample or saliva swab, and the employer sends it to a laboratory for analysis.

The results are usually confidential and shared only with the employer.

Passing the Test:

To “pass” a pre-employment drug test, a candidate’s sample should not reveal the presence of any of the tested drugs or substances. Also, if a candidate’s sample tests positive, it may result in the job offer being rescinded.

Legal Considerations:

Employers must adhere to local, state, and federal laws and regulations when conducting pre-employment drug tests. This includes ensuring the privacy and dignity of the candidate during the testing process and following proper chain-of-custody procedures for the samples.

Purpose of Testing:

Employers conduct pre-employment drug tests for various reasons. So, it includes promoting workplace safety, reducing the risk of accidents and injuries, maintaining a drug-free workplace, complying with industry regulations, and upholding company policies.

What are the Types of Drug Tests?

There are many types of drug tests and each has a different procedure. Let’s find out some basic types of drug testing.

Urine Drug Tests:

Urine drug tests are one of the most common types of drug tests. Also, in this test, a person provides a urine sample, and then the test analyzes it for the presence of specific drugs or their metabolites. 

Urine tests can detect a wide range of drugs, including marijuana, cocaine, amphetamines, opioids, and more. So employers often use them in pre-employment screening and random drug testing due to their accuracy and ease of administration.

Saliva Drug Tests:

Saliva drug tests, also known as oral fluid tests, involve collecting a saliva sample from the mouth. These tests are less invasive than urine tests and can detect recent drug use. Also, law enforcement commonly uses them in roadside drug testing for substances like marijuana, cocaine, amphetamines, and opioids. Saliva tests are preferred when immediate results are needed.

Hair Follicle Drug Tests:

Hair follicle drug tests are effective in detecting long-term drug use. However, a small sample of hair, typically from the head, is collected and analyzed for the presence of drug metabolites. 

This type of test can identify drug use over a more extended period, sometimes up to 90 days. It is often used in situations where a history of drug use is crucial, such as in legal cases.

Blood Drug Tests:

Blood drug tests are highly accurate and can detect the presence of drugs in the bloodstream. Medical settings, such as hospitals, primarily use them to assess drug intoxication or in cases of suspected impaired driving. 

Blood tests can identify both recent and ongoing drug use, making them suitable for situations where precise drug detection is necessary.

Sweat/Patch Drug Tests:

Sweat or patch drug tests involve wearing a patch on the skin that collects sweat over an extended period. However, these tests are used to monitor drug use over time and are often employed in rehabilitation programs or probation monitoring.

They are less invasive than blood tests but can provide continuous information about drug use.

Breathalyzer Tests (Alcohol):

Law enforcement officers commonly administer breathalyzer tests during traffic stops to detect alcohol consumption by measuring the alcohol content in a person’s breath. Also, they use these tests to determine if a driver is under the influence of alcohol. While not a drug test per se, they play a crucial role in detecting impairment.

Point-of-Care Tests:

Healthcare professionals often use point-of-care drug tests as rapid screening tests that can provide quick results on-site. Also, they often use these tests in workplaces, schools, and rehabilitation centers for preliminary testing. However, if needed, more comprehensive testing usually follows since they may not be as accurate as laboratory-based tests.

Each type of drug test has its advantages and limitations, making them suitable for different situations and purposes. Also, the choice of which test to use depends on factors such as the drugs they are going to test for, the required detection window, and the level of invasiveness that a particular setting finds acceptable.

What Are 5-Panel and 7-Panel Drug Tests?

The terms “5-panel” and “7-panel” refer to specific variations of urine drug tests that target different classes of drugs. These panels are commonly used in workplace and pre-employment drug testing to detect a range of substances. Let’s delve into what these panels test for:

5-Panel Urine Drug Test:

A 5-panel urine drug test is one of the most basic and commonly administered drug tests. It screens for the presence of five major drug categories:

  1. Marijuana (THC)
  2. Cocaine.
  3. Amphetamines.
  4. Opiates
  5. Phencyclidine (PCP)

A 5-panel test is often the minimum requirement for many employers and organizations conducting drug screenings.

7-Panel Urine Drug Test:

A 7-panel urine drug test expands on the 5-panel test by including two additional drug categories:

  1. Benzodiazepines
  2. Barbiturates

The 7-panel test is more comprehensive than the 5-panel test and is often used when a broader range of drugs needs to be screened. This can be important in workplaces where certain prescription medications could affect an employee’s performance or safety.

However, different organizations and industries may use customized drug panels based on their specific needs. For example, some may opt for a 10-panel test, which includes additional drugs like methadone or propoxyphene. The choice of the panel depends on factors such as industry regulations, safety concerns, and the prevalence of certain drugs in the local area.

In a nutshell, healthcare professionals commonly use both 5-panel and 7-panel urine drug tests as common tools to screen for drug use in various settings.

The number of panels in the test determines which specific drugs and drug categories they assess, with the 7-panel test covering a broader range than the 5-panel test.

What Does a Pre-Employment Drug Test Look For?

A pre-employment drug test is a crucial part of the hiring process for many companies and organizations. Its primary purpose is to ensure that prospective employees are not using illegal drugs or abusing prescription medications that could affect their job performance or workplace safety. 

Here’s a detailed look at what a pre-employment drug test typically looks for:

  1. Marijuana (THC): Pre-employment drug tests often include screening for marijuana use. This is because marijuana, or its active compound THC, can impair cognitive function and reaction times, potentially posing safety risks in certain jobs.
  2. Cocaine: Cocaine is a powerful stimulant, and its use can lead to impaired judgment and erratic behavior. Detecting cocaine use is crucial, especially in safety-sensitive positions.
  3. Amphetamines: This category includes drugs like amphetamines and methamphetamines. These substances are stimulants that can increase alertness but also pose a risk of addiction and potential workplace issues.
  4. Opiates: Opioids, including heroin, morphine, and codeine, are powerful pain-relieving drugs. Detecting their presence is essential to prevent addiction-related problems and ensure workplace safety.
  5. Phencyclidine (PCP): PCP is a hallucinogenic drug that can cause severe disorientation and unpredictable behavior. Its inclusion in pre-employment drug tests helps identify individuals using this dangerous substance.
  6. Benzodiazepines: These drugs, like Valium and Xanax, are used to treat anxiety and sleep disorders. Detecting them is important, as they can cause drowsiness and impair job performance, especially in safety-critical roles.
  7. Barbiturates: Barbiturate medications, though less commonly prescribed today, are central nervous system depressants. Detecting them is necessary to ensure that employees are not using substances that could cause drowsiness or impair their ability to perform their duties.
  8. Other Customized Panels: Depending on the employer’s specific needs and industry regulations, pre-employment drug tests may include additional substances or drugs not covered in the standard 5- or 7-panel tests. These could include synthetic opioids, methadone, or other drugs of concern.

What is a Drug Test Prescription Verification?

Drug test prescription verification is a process that some employers or organizations use to ensure that a positive drug test result is not due to the legitimate use of prescription medications. 

It involves confirming that an employee or candidate’s use of specific prescription drugs is authorized and does not violate workplace drug policies. Here’s how drug test prescription verification typically works:

1. Disclosure of Prescription Medications:

Before undergoing a drug test, employees or candidates are often required to disclose any prescription medications they are currently taking to their employer or the testing facility. This information is usually provided in a confidential manner.

2. Verification with Medical Professionals:

Once the prescription medications are disclosed, the employer or testing facility may contact a medical professional, such as the prescribing physician or pharmacist, to verify the legitimacy of the prescriptions. They may confirm the following details:

  • The name of the prescribed medication.
  • The medical condition or reason for the prescription.
  • The dosage and usage instructions.

3. Confirmation of Legitimate Use:

If the verification process confirms that the individual is using prescription medications as directed by a healthcare professional and in accordance with applicable laws, the positive drug test result is considered legitimate and not a violation of drug policies.

4. Privacy and Confidentiality:

It’s important to note that all information related to an individual’s prescription medications and medical history must be handled with the utmost privacy and confidentiality. This information should not be used for any purpose other than the verification of drug test results.

5. Accommodations and Considerations:

In some cases, if an employee or candidate’s prescription medication use affects their ability to perform certain job functions safely, employers may need to make accommodations or adjustments to their duties to ensure compliance with workplace safety requirements.
