4 Panel Drug (No Thc) Screen Vs. 5 Panel Drug Screen

Pre employment drug testing is a common practice in many workplaces, especially for safety-sensitive positions or regulated industries. Employers use drug tests to screen applicants and employees for substance abuse, which can impair their performance, productivity, and safety. However, not all drug tests are the same. Different types of drug tests can detect different substances, have different detection windows, and have different advantages and disadvantages.

In this article, we will compare two of the most widely used drug tests: the 4 panel drug (no THC) screen and the 5 panel drug screen. We will explain what each test screens for, how they work, how long they can detect drugs, and what factors to consider when choosing between them.

What is a 4 Panel Drug (No THC) Screen?

A 4 panel drug (no THC) screen is a urine-based test that screens for four commonly abused drugs: cocaine, opiates, amphetamines, and phencyclidine (PCP). This test does not screen for marijuana (THC), which is the most prevalent illicit drug in the United States1. A 4 panel drug (no THC) screen is also known as a 4 panel drug test without THC or a 4 panel drug test PCP.

A 4 panel drug (no THC) screen works by detecting the presence of metabolites, which are the byproducts of drug use that remain in the body after the drug has been metabolized. The test uses a urine sample from the individual being tested, which is sent to a laboratory for analysis. The laboratory uses an immunoassay method to identify the metabolites of the four drugs. If any of these drugs are detected, the test will come back positive.

A 4 panel drug (no THC) screen can detect drugs for different periods of time, depending on the type of drug, the amount and frequency of use, the individual’s metabolism, and other factors. Generally speaking, a 4 panel drug (no THC) screen can detect drugs for the following time frames2:

  • Cocaine: 2 to 4 days
  • Opiates: 2 to 4 days
  • Amphetamines: 2 to 5 days
  • PCP: 3 to 7 days

A 4 panel drug (no THC) screen is often used by employers who want to test for four major illicit drugs but do not want to test for marijuana. This may be because marijuana is legal for medical or recreational use in their state, or because they do not consider marijuana use as a serious issue for their workplace. A 4 panel drug (no THC) screen is also cheaper and faster than a 5 panel drug screen.

What is a 5 Panel Drug Screen?

A 5 panel drug screen is a urine-based test that screens for five commonly abused drugs: cocaine, opiates, amphetamines, phencyclidine (PCP), and marijuana (THC). This test is also known as a standard 5 panel drug test or a SAMHSA-5 test.

A 5 panel drug screen works in the same way as a 4 panel drug (no THC) screen, except that it also screens for marijuana. The test uses a urine sample from the individual being tested, which is sent to a laboratory for analysis. The laboratory uses an immunoassay method to identify the metabolites of the five drugs. If any of these drugs are detected, the test will come back positive.

A 5 panel drug screen can also detect drugs for different periods of time, depending on the type of drug, the amount and frequency of use, the individual’s metabolism, and other factors. Generally speaking, a 5 panel drug screen can detect drugs for the following time frames2:

  • Cocaine: 2 to 4 days
  • Opiates: 2 to 4 days
  • Amphetamines: 2 to 5 days
  • PCP: 3 to 7 days
  • Marijuana: up to 30 days

A 5 panel drug screen is often used by employers who want to test for five major illicit drugs, including marijuana. This may be because marijuana is illegal in their state or under federal law, or because they consider marijuana use as a serious issue for their workplace. A 5 panel drug screen is also required by some regulated industries, such as transportation or law enforcement.

How to Choose Between a 4 Panel Drug (No THC) Screen and a 5 Panel Drug Screen?

There is no definitive answer to which type of drug test is better or more suitable for your needs. It depends on various factors, such as your industry, your state laws, your company policy, your budget, your testing objectives, and your preferences. However, here are some general guidelines to help you make an informed decision:

  • If you are required by law or regulation to test for marijuana, you should use a 5 panel drug screen.
  • If you are not required by law or regulation to test for marijuana, but you want to test for it anyway, you should use a 5 panel drug screen.
  • If you are not required by law or regulation to test for marijuana, and you do not want to test for it, you should use a 4 panel drug (no THC) screen.
  • If you want to save money and time, you should use a 4 panel drug (no THC) screen.
  • If you want to be more comprehensive and thorough, you should use a 5 panel drug screen.

Regardless of which type of drug test you choose, you should always consult with a qualified background check provider, like GoodHire, for background checks. A background check provider can help you with the following:

  • Ensure that your drug testing program is compliant with federal, state, and local laws and regulations.
  • Provide you with reliable and accurate drug testing results from certified laboratories and medical review officers.
  • Protect the privacy and rights of your applicants and employees throughout the drug testing process.
  • Support you with customer service and technical assistance whenever you need it.

Conclusion

Drug testing is an important tool for employers to maintain a safe, productive, and drug-free workplace. However, not all drug tests are the same. Depending on your needs and preferences, you may choose between a 4 panel drug (no THC) screen and a 5 panel drug screen. Both types of tests have their pros and cons, and you should weigh them carefully before making a decision.
