What labs drug test (popular testing companies), how do they test, and what do they test for?

Here is a list of labs that do drug testing


Laboratory Corporation of America

Laboratory Corporation of America is one of the leading providers of urine drug testing services in the United States. Their drug laboratories are certified by the Substance Abuse and Mental Services Administration (SAMHSA). It conducts urine drug analyses in accordance with the Department of Transportation and Department of Health and Human Services.

Standard urine drug testing panels include from five to ten drugs, including hydrocodone, codeine, hydromorphone, oxymorphone, methadone,tramadol, buprenorphine, oxycodone, morphine, fentanyl, and meperidine. There is specimen validity testing that can detect specimen substitution or adulterants that result from the attempts of donors to mask the use of drugs.

Initial drug screening is performed by using immunoassay - a special type of drug test that uses antibodies in order to detect the presence of drugs or other forbidden substances in the urine. However, this test cannot measure the exact amount of drugs present in urine.

In most cases, it takes no more than two weeks to receive test results. The most common reasons for delay are either the lack of personal information or its inaccuracy.

Quest Diagnostics Incorporated

Quest Diagnostics is one of the leaders in clinician-ordered drug testing services. Drug testing for employers or individuals is always available at Quest Laboratories throughout the United States. National Drug Screening works in cooperation with Quest Diagnostics by providing both inside and onsite lab tests (oral fluid, urine, and hair), drug tests, and services and programs.

Quest Diagnostics offers one of the most reliable urine drug testing panels that comply with the testing standards of the US Department of Transportation (DOT). It tests for the following drugs: amphetamines, barbiturates, marijuana, opiates, synthetic cannabinoids, synthetic stimulants, cocaine, methadone, Ecstasy, metabolites, oxycodone, and propoxyphene.

Testing is performed immediately after the specimen arrives at one of the Quest labs. In most cases, negative results are released within 24 hours. Positive results must undergo additional confirmatory testing and are usually available within 72 hours.

Abbott Laboratories

Abbott Laboratories is another world leader in toxicology solutions. It uses one of the most sensitive, advanced, and sophisticated technologies and equipment in order to screen and confirm drugs present in urine. The methodologies of Abbott Laboratories provide legally defensible and highly accurate results. Abbott also offers rapid urine screening devices that provide convenient and comprehensive drug testing solutions.

The comprehensive drug tests offered by Abbott Laboratories are capable of detecting hundreds of illicit drugs, alcohol, and commonly abused prescriptions that usually pass routine urine drug tests. Abbott Labs also performs the 10-panel drug test for the five most common drugs of abuse in the United States, including amphetamines, cocaine, cannabis, opioid, barbiturates, and benzodiazepines.

The results can be negative, positive, or inconclusive. In most cases, negative results are ready within 24 hours. If the result is positive, then an individual will receive it within 72 hours after confirmatory testing.
