Drug Testing Services We Offer in San Diego, CA

San Diego houses dozens of major industries, including transportation, shipping, and education. However, one industry has stricter regulations than the others – the military. Many employees in these industries are subject to pre-employment, random and post-accident drug tests.

If you manage your company’s drug testing program, National Drug Screening can help. We even offer individual drug tests for those who need them. Explore our list of drug testing services in San Diego below:

Workplace Drug Testing

Every employer hopes to have a drug-free workforce, but hoping isn’t nearly enough to ensure that outcome. Our workplace drug testing services effectively identify drug users within your workplace and provide the tools required to set up usage prevention programs.

Immediate Drug Testing Services

You need information quickly in urgent situations like pre-employment, workplace accidents or court orders.

Our immediate testing services can be administered on the same day they’re ordered and deliver lab-confirmed negative results in one business day. Positive results require more time – usually two to three days. Some of our facilities in San Diego will also offer instant drug testing with same day negative results.

DOT-Regulated Tests

The Department of Transportation (DOT) regulates businesses operating in the transportation industry. Employees in this sector must regularly pass randomly administered five-panel drug tests. Our screenings generate accurate results and adhere to the handling and chain of custody procedures laid out by the DOT. Having a vender that can provide DOT compliant drug testing services is critical to avoiding fines and penalties.

Individual Drug Testing Options

Occasionally, private citizens may require drug tests. Below are a few common reasons for individual drug testing:

  • Probation requirements
  • Divorce proceedings
  • Child custody hearings
  • School admissions
  • Any personal reasons


National Drug Screening offers reputable individual drug screenings for all these scenarios and countless others. Immediate drug test ordering is always available.

Drug Testing Services FAQ

What are the main types of drug screenings?

Not all drug tests serve the same purpose. Each screening method detects a particular set of drugs and usage patterns. Understanding the most common drug testing options empowers you to create effective, custom testing protocols.

There are three main types of drug tests: urine, saliva (oral fluid), and hair follicle. Urine and hair follicle tests are the most common, though each type serves a different purpose:

  • Urine drug tests: These tests analyze a urine sample to determine whether drug compounds are present. Drug compounds quickly appear in urine, so drugs consumed that same day can usually be detected.
  • Saliva or oral fluid drug tests: Saliva tests, or mouth-swab tests, use a small sample of saliva swabbed from inside a subject’s cheek to screen for drugs. This non-invasive test is ideal for detecting very recent drug use.
  • Hair follicle drug tests: These tests analyze a small sample of hair from the subject’s body to detect drug compounds in the hair’s structure. They are excellent at detecting long-past drug use, as compounds remain in the hair for months.


If you’re still unsure which drug testing method is best for your purposes, call us! Our experts can guide you to the screening type and panel that best detects the usage patterns and drug compounds that concern you most. Our Drug Testing Info page on our web site has a wealth of information regarding common drug testing, specimen types, alcohol testing and information about the individual drugs we test for.
