What this test measures
This 6-panel drug test uses a urine sample to screen for six classes of commonly used substances and their metabolites. A metabolite is a biomarker that appears in the urine after a drug is processed by the body. The test detects marijuana (THC-COOH), cocaine metabolites (benzoylecgonine), opiates including morphine and codeine, amphetamines, benzodiazepines, and oxycodone. Each substance has a specific cutoff level that determines whether the result is positive or negative. Detection times vary greatly depending on the type of drug, the amount consumed, and individual metabolism. This testing panel provides a comprehensive overview of recent substance use and is commonly used for employment screening, personal monitoring, and compliance purposes. The test provides confidential results with no doctor visit required, making it accessible for individuals who need drug screening for various personal or professional reasons.
What's included
Who should consider this test
You might consider this test if you are experiencing any of the following:
- Individuals preparing for employment opportunities or workplace drug screening requirements
- People who need to demonstrate sobriety for legal, custody, or probation-related matters
- Those participating in substance abuse treatment programs who want to monitor their progress
- Parents or family members concerned about potential substance use by loved ones
- Individuals in safety-sensitive positions who want to verify their clean status before required testing
- People taking prescription medications who want to understand how they may appear on drug tests
What to expect
Preparation
No special preparation needed. Avoid excessive water consumption before the test as this may dilute your sample and require retesting. Bring a valid photo ID to your appointment.
Sample Type
You'll provide a urine sample in a private collection cup. The process takes just a few minutes in a private restroom facility.
Collection
Visit any participating Quest Diagnostics or LabCorp location. Present your ID and test order confirmation. A trained technician will guide you through the simple collection process while maintaining your privacy and dignity.
Turnaround
Results are typically available within 1-3 business days and will be delivered securely through your online portal with email notification.
Understanding your results
Results are reported as either positive (drug concentration at or above the specified cutoff level) or negative (drug concentration below the cutoff level). Each substance tested has its own cutoff level designed to minimize false positives while accurately detecting recent use. These cutoff levels help reduce false positives due to incidental exposure, prescription use, or environmental factors, and can vary depending on the testing panel and laboratory standards. Your lab report will include the specific reference ranges and cutoff levels used by the laboratory that processed your sample.
| Population | Reference Range | Notes |
|---|---|---|
| Marijuana (THC) | 50 ng/mL cutoff | Detection window: 3-30 days depending on usage frequency |
| Cocaine metabolite | 150-300 ng/mL cutoff | Detection window: 2-4 days after use |
| Amphetamines | 500 ng/mL cutoff | Detection window: 2-5 days after use |
| Benzodiazepines | 300 ng/mL cutoff | Detection window: 3-8 days, longer for long-acting variants |
| Opiates | 300 ng/mL cutoff | Detection window: 1-3 days for most opiates |
| Oxycodone | 100 ng/mL cutoff | Detection window: 1-3 days after use |
Reference ranges and cutoff levels shown are general guidelines. Your lab report will include the specific cutoff levels and reference ranges used by the laboratory that processed your sample, which is the authoritative standard for interpreting your results.
What does a “Low” result mean?
A negative result means no substances were detected above the cutoff levels. This typically indicates no recent use within the detection window, though very recent use (within hours) or use of substances not included in this panel may not be detected.
What does a “High” result mean?
A positive result indicates that the substance or its metabolites were detected at or above the laboratory's cutoff level. This typically means the substance was used within the detection window for that particular drug. Positive results may require confirmatory testing for legal or employment purposes.
Privacy & confidentiality
