Frequently Asked Questions
What are the benefits of on-site mobile drug testing for employers?
On-site mobile drug testing completely eliminates employee travel time and reduces wait times at standard clinics. By bringing our certified collectors directly to your facility in San Dimas or the greater Los Angeles County area, you minimize productivity loss and prevent employees from being unsupervised off-site.
Are your mobile testing services DOT-compliant?
Yes, absolutely. Our mobile collectors are fully trained and certified to perform DOT-mandated drug and alcohol testing. We follow strict federal chain-of-custody protocols for FMCSA, FAA, and FTA requirements, ensuring your business stays 100% compliant during random, pre-employment, or reasonable suspicion screening.
Do you provide emergency post-accident drug testing?
Yes, we offer rapid-response post-accident drug and breath alcohol testing. If a workplace accident occurs in Southern California, our mobile unit can be dispatched to your location or the accident scene to help you meet the strict, time-sensitive compliance requirements of OSHA and DOT regulations.
What types of specimens can be collected on-site?
Our mobile units are equipped to handle all standard collection methods just like a physical clinic. This includes standard 5-panel and expanded 10-panel urine testing, oral fluid (saliva) testing for recent impairment, and hair follicle collections. We also conduct on-site breath alcohol testing (BAT).
What areas do your mobile drug testing units serve?
We are proudly based in San Dimas, CA, and our mobile testing services cover a wide radius across Los Angeles County, the Inland Empire, and surrounding Southern California regions. Contact us to see if your facility is within our standard dispatch zone.
Random Drug Testing Programs
Maintain a safe, productive, and drug-free workplace. Our scientifically managed random drug testing programs ensure fairness, legal compliance, and unpredictability to effectively deter substance abuse in your organization.
Contact Us to Set Up Your PoolWhy Implement Random Testing?
Effective Deterrence
The unannounced, unpredictable nature of random testing is widely proven to be the most effective method for deterring employee drug and alcohol use.
Fair & Unbiased
We use scientifically valid, computer-generated selection software to ensure every employee has an equal chance of being chosen, completely eliminating employer bias.
Regulatory Compliance
Our programs are designed to keep you fully compliant with DOT regulations (FMCSA, FAA, FTA, etc.) and state-specific laws for non-regulated employers.
Reduced Liability
Identify risks before they turn into incidents. Random testing helps lower workplace accident rates, decrease absenteeism, and minimize your corporate liability.

Drug Testing: 2026 Educational Center
What are the most common types of drug tests?
Employers and testing facilities primarily use four types of biological samples, depending on the required detection window:
- Urine Testing: The most common method. It is highly practical and detects drug metabolites for hours to days after use (or weeks for heavy cannabis use).
- Saliva (Oral Fluid): Best for detecting very recent use (within hours up to 48 hours). It is difficult to tamper with and is now formally recognized in 2026 federal guidelines.
- Hair Testing: Used to identify long-term patterns of drug use. It provides a detection window of up to 90 days but is not useful for detecting very recent use (within the past few days).
- Blood Testing: Measures active drug levels for current impairment. It has a very short detection window (minutes to hours) and is usually reserved for emergency, legal, or post-accident settings.
What drugs do standard panels test for?
Workplace screening usually utilizes standard or expanded panels:
- 5-Panel Test (Standard): Typically screens for Marijuana (THC), Cocaine, Amphetamines (including meth), Phencyclidine (PCP), and Opioids.
- 10-Panel Test (Expanded): Includes all 5-panel drugs, plus Benzodiazepines, Barbiturates, Methadone, and additional prescription or synthetic drugs.
2026 Federal Update: Due to rising workplace positivity rates, Fentanyl is now increasingly included in expanded panels and has been officially added to federal safety-sensitive drug testing panels.
How long do drugs and alcohol stay in my system?
Detection windows vary based on the drug, dose, frequency of use, and metabolism. General guidelines for urine testing include:
- Amphetamines, Cocaine, & Opiates: Generally detectable for 1 to 4 days.
- Marijuana (THC): 2 to 7 days for single use, but can remain detectable for 1 to 2 months or longer for chronic, heavy users.
- Alcohol: Standard tests detect alcohol for 2 to 12 hours. However, specialized EtG (ethyl glucuronide) testing can detect alcohol metabolites for 24 to 72 hours after consumption.
Can a test result in a false positive? (CBD, Poppy Seeds, etc.)
Credible drug screening programs use a highly accurate two-step process to eliminate false positives. An initial immunoassay screen is performed. If it is non-negative, a highly specific GC/MS (gas chromatography-mass spectrometry) test confirms the exact substance, making false positives extremely rare.
What about CBD? Pure CBD will not cause a positive result. However, because OTC CBD products are largely unregulated, some contain trace amounts of THC which can trigger a positive marijuana test.
What about Poppy Seeds? Poppy seeds naturally contain trace amounts of morphine and codeine. Modern tests use elevated "cutoff" levels specifically designed to avoid flagging typical dietary intake (like eating a poppy seed bagel).
Can employers still drug test if marijuana is legal in my state?
Yes. Employers can generally still drug test for marijuana and maintain drug-free workplace policies, even in states where medical or recreational use is legal (like California). However, laws are evolving rapidly.
Some states now have employee protections that limit an employer's ability to take action based solely on off-duty, legal marijuana use unless the employee is in a safety-sensitive position. Because marijuana remains illegal under federal law, federal contractors and DOT-regulated employees (like CDL drivers) are always strictly prohibited from using marijuana, regardless of state law.
