Urine Drug and Alcohol Testing in Corona

Urine drug testing is the most common type of drug testing in the United States. Many employers conduct employee drug testing but it is still an often misunderstood process. Urine drug testing is conducted as an instant, point of collection, test or as a lab based test. It is easy to collect and transport, inexpensive to test, accurate, and provides a detection window deemed adequate by most employers. Urine drug testing has been around for over 25 years and has held up in court systems as reliable and legally defensible. The most common drug testing panels are:

  • Five Panel: Cocaine, Marijuana (THC, cannabinoids), Phencyclidine (PCP – angel dust), Amphetamines (including Ecstasy and methamphetamines, also known as crystal meth), Opiates (including heroin, codeine and morphine)
  • Ten Panel: All above plus Benzodiazepines (such as Xanax), Barbiturates, Methadone, Propoxyphene, Methaqualone (Quaaludes)
  • Ten Panel with Expanded Opiates: All above plus hydrocodone, hydromorphone, oxycodone and oxymorphone.
  • DOT Five Panel: Cocaine, Marijuana (THC, cannabinoids), Phencyclidine (PCP – angel dust), Amphetamines (including Ecstasy and methamphetamines, also known as crystal meth), Opiates (including heroin, codeine and morphine).

Hair Follicle Drug and Alcohol Testing in Corona

Employers throughout the United States are now implementing hair testing programs due to the benefits this alternative specimen offers. Hair follicle drug testing is becoming increasingly popular. Hair testing can detect the drugs/metabolites taken up to 90 days, can evaluate long-term patterns of repetitive drug use, and is flexible in drug panels and can also test for EtG alcohol in hair. Same day service is available for hair testing with a 3-4 business day turnaround for final hair drug testing results.

Alcohol Specific Testing in Corona

US Drug Test Centers in Corona can also run alcohol specific tests. These include a variety of urine tests, hair tests, and breath alcohol testing. The EtG hair test measures the average ingestion of Ethyl Alcohol over a three month period. While this does not detect current impairment it can indicate a behavioral issue.

Corona's Most Accurate Drug or Alcohol Testing

How do I know if the test is accurate? All of US Drug Test Centers' specimens go to a SAMHSA certified laboratory for testing. SAMHSA has an active advisory board that keeps its employees and administrators abreast of current and changing laws when it comes to drug testing. There are Mandatory Guidelines for Federal Employee Drug Testing Programs that must carry consistencies throughout every agency and company that SAMHSA laboratories supplies. The advisory board has professionals that are uniquely qualified in their respective fields to review scientific evidence in the area of drug and alcohol treatment and testing practices.

California Drug Testing FAQs

Do employers in California need to comply with mandatory state-specific rules when drug & alcohol testing?
Yes. California has rules based on court rulings, rather than legislative action.
Is a Drug-Free Workplace policy required in California?
No, however, employers are strongly encouraged to have a written policy in place (Policy is specifically required to comply with the California’s voluntary law). Employers are also strongly encouraged to warn employees and applicants and get signed acknowledgments of the warning, that the use of medication from a foreign source may cause a positive drug test.
What are some compliance requirements in California?
Random testing is limited to safety-sensitive employees only. Employers are encouraged not to let an applicant begin work before the pre-employment drug test result is known.  A reasonable suspicion test unsupported by facts is an unauthorized random test. Requiring a drug test collection during off-duty hours may be prohibited. Employers based in San Francisco are limited in what they can and cannot do, due to a city ordinance.
Are employers in California able to use drug screening for any other claim defenses or state-specific financial benefits?
Yes. Employers may leverage an ‘Intoxication’ defense to a Workers’ Compensation Claim, based on a positive drug test result. A positive drug test may also make an employee ineligible for unemployment compensation. Employers wishing to leverage either of these benefits must voluntarily comply with very detailed program rules.
Does California authorize marijuana (THC) or cannabidiol (CBD) use?
Yes. California permits the personal adult use and the medical use of marijuana for patients that meet specific medical conditions. The laws do not specifically impact employment drug testing programs.
