Drug Testing Services We Offer in San Jose, CA

San Jose’s most prominent local employers include tech firms and defense and healthcare companies, all subject to federal drug testing regulations. To help ensure compliance with these rules, we provide the following drug testing services:

Workplace Testing Services

Drug use in the workplace can create hazardous conditions, particularly in the healthcare sector. Our workplace drug testing services can screen for up to 14 drug compounds simultaneously.

Marijuana Testing For Employers in San Jose, CA

Employment drug testing for marijuana is limited in San Jose and in all of California due to a new law that went into effect Jan 1, 2024 – AB 2188. The trend in California regarding drug testing and marijuana is moving towards protecting employees who use legal marijuana off duty and the fact that our traditional workplace drug testing does not measure workplace impairment. Urine testing for marijuana is now restricted, oral fluid testing is recommended. Oral fluid testing detects the parent drug of marijuana so could be an option for employer drug testing particularly for reasonable suspicion and post-accident. Oral fluid drug testing shows recent use of drugs, and it is not testing the metabolite of marijuana – THC – a nonpsychoactive cannabis metabolite.

Immediate Drug Testing Services

Quick drug testing is essential when faced with situations like court orders or workplace incidents. Our immediate drug testing services can be arranged and executed on the same day.

Negative results are typically generated on the following business day, while potential positives require an additional two to three days. Instant drug testing with same day negative results are also available at our San Jose, CA facilities.

DOT Regulated Tests

Industries regulated by the Department of Transportation (DOT), such as air travel, trucking and shipping, must adhere to specific drug testing procedures. We offer DOT-compliant drug tests and related services to ensure compliance with random screening requirements. Random testing and consortium services are available, just call 866-843-4545.

We offer reliable drug testing services for all these reasons and countless others. These tests can even be ordered on the same day. Just call 866-843-4545 or order online for immediate drug testing services.

Common Drug Test Panels in San Jose, CA

Though cannabis is legal in California, it remains prohibited in many workplaces. To address concerns about both recent and past cannabis use, San Jose companies need comprehensive testing protocols that identify a range of drug usage patterns. We offer the following testing services to meet this need:

10-Panel Drug Test

The 10-panel drug test identifies ten different drug compounds, including THC, opiates, barbiturates, amphetamines, and benzodiazepines. This test can be ordered without the THC included for companies wishing to drop marijuana from their testing panel.

Oral Fluid or Saliva Sample Drug Testing

For the detection of recent drug use, oral fluid testing is the preferred method. This is a great solution for California employers who want to continue to test for marijuana. This is an easy collection typically performed on the employer premises by an employer representative. Oral fluid testing is available as lab based or as an instant testing product. For employees in remote areas or working from home a remote proctored oral fluid testing solution is available.

Urine Sample Drug Testing

Urine sample drug tests are among the most commonly used specimen collection methods. These tests can detect a variety of drug compounds. Due to the rapid turnover of urine in the body, these tests are not the best choice for pinpointing long-past drug use. Detection times with urine are typically from 1 to 5 days.

Hair Drug Testing

Hair follicle drug testing is effective for identifying long-term drug use, as drug compounds can remain in the hair for months. However, this method is less useful for detecting very recent drug use, as drug compounds take longer to appear in hair than in urine or saliva. Detection time for hair drug testing is typically from 7 days out to up to 90 days.
