Drugs Of Abuse: 9 Drugs
- Why is it done?
- Detects the presence of nine common drugs of abuse in urine or blood samples
- Typically screens for: Amphetamines, Cocaine, Marijuana (THC), Opioids, Phencyclidine (PCP), Benzodiazepines, Barbiturates, Methadone, and Propoxyphene
- Ordered for workplace drug screening programs and pre-employment testing
- Used in clinical settings to monitor patients with substance abuse disorders or compliance with treatment
- Performed during emergency department evaluations when drug intoxication is suspected
- May be required as part of legal proceedings, probation monitoring, or pain management contracts
- Assists in identifying substance abuse in patients presenting with unexplained psychiatric or medical symptoms
- Normal Range
- Normal/Negative Result: No detectable levels of any of the nine drugs; typically expressed as "negative" or "<cutoff level" for each substance
- Cutoff Levels (typical thresholds): Amphetamines: 500 ng/mL (urine), Cocaine: 150 ng/mL (urine), THC: 50 ng/mL (urine), Opioids: 300 ng/mL (urine), PCP: 25 ng/mL (urine), Benzodiazepines: 200 ng/mL (urine), Barbiturates: 200 ng/mL (urine), Methadone: 300 ng/mL (urine), Propoxyphene: 300 ng/mL (urine)
- Units of Measurement: Nanograms per milliliter (ng/mL) for urine samples; micrograms per liter (μg/L) or ng/mL for blood samples
- Positive Result: Presence of one or more drugs above the established cutoff threshold; indicates recent use of that substance
- Interpretation: Negative = No drugs detected; Positive = Drug detected above cutoff level; Borderline/Inconclusive = Levels near cutoff requiring confirmation with more specific testing (GC-MS)
- Interpretation
- Negative Result: Indicates no drugs of abuse above cutoff levels detected; patient is unlikely to have used these substances recently; considered "normal" in most contexts
- Positive Result: Confirms presence of one or more drugs above detection threshold; does not quantify amount of drug present or determine time of use
- Single vs. Multiple Positives: Detection of single drug may indicate isolated use; multiple positive results suggest polysubstance use or ongoing abuse patterns
- Factors Affecting Results: Window of detection varies by substance (THC: 2-30 days; cocaine: 2-4 days; opioids: 1-3 days); urine concentration affects detection sensitivity; certain foods, medications, or over-the-counter products may cause false positives
- False Positives: May occur with certain medications (cold medicines for amphetamines, poppy seeds for opioids); require confirmation with gas chromatography-mass spectrometry (GC-MS)
- False Negatives: Possible if use occurred before detection window; improper sample collection or storage; diluted samples; or use of substances not included in the 9-drug panel
- Clinical Significance: Positive results indicate substance exposure but do not prove impairment, addiction, or timing of use; all positive screening results should be confirmed with confirmatory testing
- Associated Organs
- Primary Organ Systems: Central nervous system (CNS), affecting brain function, behavior, and cognition; Cardiovascular system (heart and blood vessels); Respiratory system (lungs); Hepatic system (liver)
- Conditions Associated with Positive Results: Substance use disorder, drug addiction, acute intoxication, drug dependency syndrome, withdrawal syndromes
- Neurological Effects: Altered consciousness, seizures, psychosis, anxiety, paranoia, hallucinations, tremors, behavioral changes, impaired judgment
- Cardiovascular Complications: Tachycardia (elevated heart rate), hypertension, arrhythmias, myocardial infarction (heart attack), stroke, cardiomyopathy
- Respiratory Issues: Acute respiratory depression, hypoxia, aspiration risk, pulmonary edema, chronic obstructive pulmonary disease (COPD)
- Hepatic Consequences: Liver disease, cirrhosis, hepatitis (especially with injection drug use), impaired drug metabolism
- Renal System: Acute kidney injury, chronic kidney disease, rhabdomyolysis
- Infectious Complications: HIV, Hepatitis B and C (with injection drug use), endocarditis, sepsis
- Potential Risks: Overdose and death, overdose from drug combinations with depressants, aspiration during altered consciousness, trauma from accidents while intoxicated
- Follow-up Tests
- Confirmatory Testing: Gas Chromatography-Mass Spectrometry (GC-MS) is the gold standard; recommended for all positive screening results to reduce false positives
- Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS): More sensitive confirmatory method; provides quantitative results
- Extended Drug Panel Testing: If positive for specific substances, may expand panel to include additional related compounds or synthetic drugs
- Liver Function Tests: Aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin; assess hepatic damage from drug use
- Kidney Function Tests: Creatinine, blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR); evaluate renal function
- Infectious Disease Screening: HIV antibody test, Hepatitis B and C serology; recommended for patients with injection drug use history
- Cardiac Evaluation: Electrocardiogram (ECG) and troponin levels if cocaine or stimulant use suspected; assess for arrhythmias or myocardial infarction
- Complete Blood Count (CBC): Assess for infections, anemia, thrombocytopenia from drug use
- Toxicology Panel: Additional comprehensive testing for other substances not in the 9-drug screen (synthetic cannabinoids, new psychoactive substances)
- Psychiatric Evaluation: Assess for co-occurring mental health disorders, substance use disorder severity, treatment planning
- Repeat Testing: For monitoring compliance with treatment, workplace programs, or legal monitoring; typically performed at specified intervals (weekly, monthly)
- Monitoring Frequency: In treatment programs, typically every 2-4 weeks initially; in workplace settings per program requirements; for pain management patients, often monthly
- Fasting Required?
- Fasting Required: No - Fasting is not required for the Drugs of Abuse: 9 Drugs test
- Food and Drink: Patients may eat and drink normally before the test; no dietary restrictions apply
- Medications: Notify healthcare provider of all medications being taken; certain medications may affect test results or be incorrectly flagged (e.g., cold medicines containing pseudoephedrine, herbal supplements)
- Prescribed Benzodiazepines and Opioids: Inform provider if legitimately prescribed; required for proper interpretation of positive results in clinical context
- Sample Collection Instructions: For urine tests, provide mid-stream clean-catch specimen; for blood tests, standard venipuncture performed by phlebotomist
- Testing Conditions: May require directly observed collection in workplace or legal settings to prevent adulteration or substitution
- Specimen Storage: Urine samples should be refrigerated if not processed immediately; blood samples processed promptly to maintain sample integrity
- Timing: Can be performed at any time of day; no specific appointment scheduling constraints related to meals or fasting
