What this test measures
This comprehensive 11-panel drug test screens urine for evidence of recent use of commonly abused substances and alcohol. The test detects drug metabolites, which are byproducts that remain in the urine after the body has processed these substances. For alcohol detection, the test measures ethyl glucuronide (ETG) and ethyl sulfate (ETS), which are metabolites that can indicate alcohol consumption. The panel includes testing for benzodiazepines like alprazolam and lorazepam, marijuana metabolites (THC-COOH), cocaine metabolites, and various opioids including prescription pain medications.
Urine testing typically has a detection window ranging from several hours to a few days for most substances, with detection generally possible approximately 2 hours after use. However, detection times vary significantly by substance - while most drugs are detectable for 24-72 hours, alcohol metabolites can be detected for up to 80 hours, benzodiazepines for up to 10 days, and heavy marijuana use may be detectable for up to 30 days. The test provides evidence of recent or past drug use but cannot diagnose current intoxication or addiction.
What's included
Who should consider this test
You might consider this test if you are experiencing any of the following:
- Individuals who need comprehensive drug screening for employment, legal, or personal reasons and want privacy and convenience
- People concerned about potential exposure to substances and seeking confirmation through professional testing
- Those required to demonstrate sobriety for legal proceedings, custody arrangements, or probation compliance
- Individuals in recovery who want to verify their clean status for personal accountability or treatment programs
- Parents or family members who need objective information about suspected substance use in their household
- People preparing for pre-employment screenings who want to know their status beforehand
What to expect
Preparation
No special preparation is required. Avoid excessive fluid intake before testing as diluted samples may require retesting. Bring a valid photo ID to the collection facility.
Sample Type
A urine sample is collected in a sterile container at a certified laboratory collection site. The sample is typically collected under monitored conditions to ensure integrity.
Collection
Visit your chosen lab location during business hours with your test authorization and ID. The collection process takes just a few minutes and is conducted by trained professionals in a private setting.
Turnaround
Results are typically available within 1-3 business days and are delivered securely through an online portal or by phone.
Understanding your results
Results are reported as either 'Positive' or 'Negative' for each drug class tested. If a substance tests positive, the specific metabolite detected will be indicated. If any initial screening detects substances, confirmatory testing is automatically performed at no additional cost to verify the results. The lab report will include specific reference ranges and cutoff levels used for each substance tested.
| Population | Reference Range | Notes |
|---|---|---|
| All adults | Varies by substance | Each drug class has specific cutoff levels measured in ng/mL |
| Cocaine metabolites | 150 ng/mL cutoff | Detection of benzoylecgonine indicates cocaine use |
| THC metabolites | 50 ng/mL cutoff | Marijuana detection can vary significantly based on usage patterns |
| Alcohol metabolites | ETG/ETS detection | Can detect alcohol use for several days after consumption |
Reference ranges and cutoff levels shown are general guidelines. Your lab report will include the specific reference ranges and methodologies used by the laboratory that processed your sample, which are the authoritative standards for interpreting your results.
What does a “Low” result mean?
Negative results indicate that no detectable levels of the tested substances were found in the urine sample at the time of collection. This suggests either no recent use or use that occurred outside the detection window for the test.
What does a “High” result mean?
A positive result indicates the presence of a detectable amount of a substance within the testing window, but does not necessarily indicate impairment or substance use disorder. Positive results may indicate recent use of illicit drugs, misuse of prescription medications, or in some cases, legitimate medical use of prescribed substances.
Privacy & confidentiality
Drug test results are considered confidential medical information and are protected under federal privacy laws. Your results are delivered through a secure online portal and are not shared with employers, insurance companies, or other third parties without your explicit written consent. Only you and authorized personnel involved in processing your test have access to your results, ensuring complete privacy and confidentiality.
