Laboratory Drug Testing
Standard Urine Testing
One of the most common ways of screening, urine testing is an accurate and reliable
way to test for drugs of abuse and can detect casual drug use that occurred within
72 hours (1-3 days).
Specimen Validity testing
With specimen validity testing protocols, you can ensure the integrity of your urine
drug test by measuring pH, creatinine levels and specific gravity, ensuring that
no adulterant has been added to the urine specimen
Adulterants are foreign substances either ingested or added directly to a urine
specimen to prevent the detection of drug use. Promoted as "cleansing agent," these
substances range from everyday household items to specific chemical additives easily
obtained through the Internet.
A non-invasive, adulterant-resistant test for the 5 most common classes of drugs
(including ecstasy), hair testing provides accurate results and up to a 90-day history
of drug use.
Offered as laboratory-based urine or blood tests, our alcohol tests provide rapid,
accurate and reliable results.
Anabolic steroid abuse and the use of other performance-enhancing drugs has become
an increasing cause of concern. Our steroid testing detects 20 different anabolic
agents (and their metabolites) commonly used by body builders, distance runners
and other athletes. Our panel also includes testing for masking agents (e.g. probenecid,
used for blocking the urinary excretion of some steroids). Drug identification and
confirmation is done using the chromatography/ mass spectrometry (GC/MS) technology.
Point-of-Collection Testing (On-site)
With Express Results® you can test a urine sample on-site and obtain
results within a matter of minutes. Testing can be conducted for 1 to 10 drugs at
one time, and you can read the results for up to 60 minutes.
Q.E.D.® (Instant Saliva Alcohol Testing)
Designed for alcohol-use detection, the non-invasive Q.E.D.® onsite
saliva test highly accurate results with quick readouts.
Our basic panels, either point-of-care or lab-based, test for following drugs:
In addition to these 10 drugs, Quest Diagnostics has the capability to test for
other commonly abused drugs such as Oxycodene, MMDA (Ecstacy) or Ketamine
When to Test?
Pre-employment drug screening is a good practice and is the first step to creating
a drug-free, cost-effective, highly productive workplace.
How Drug Testing Works?
All substance abuse specimens submitted to Quest Diagnostics are initially tested
using a screening technique called enzyme immunoassay (EIA), which is an objective,
computerized and automated method to ensure reliable results. Quest Diagnostics
also offers secondary confirmation by Gas Chromatography/ Mass Spectrometry (GC/MS),
considered by many experts to be the gold standard in drugs of abuse confirmation
