SCREENING ASSAYS
Once a urine specimen is received in one of our labs, it is scanned into the system and receives a unique lab accession number of the most reliable identification and tracking. Then, an alliquoted sample undergoes validity testing (as a part of initial testing) using PH values, specific gravity and creatinine to ensure it is a human sample and that it has not been diluted or adulterated. Along with this, the urine sample will be screened for the presence or absence of benzodiazepines, opiates, and other illicit drugs using Diatron P500.

FAQ's
Urine Drug Testing (UDT) is a diagnostic method used to detect the presence of prescription medications, illicit substances, or their metabolites in a urine sample. It is commonly utilized for:
→ Medication adherence monitoring
→ Substance misuse detection
→ Workplace and occupational safety compliance
Urine is the preferred sample type for drug testing due to:
→ Non-invasive collection
→ Ease of handling and storage
→ Longer detection window compared to blood and saliva
DLW’s Urine Drug Testing panel can detect a wide range of substances, including:
→ Opioids
→ Cannabinoids (THC – Marijuana)
→ Cocaine
→ Amphetamines
→ Benzodiazepines
→ Barbiturates
→ Methadone
→ Phencyclidine (PCP)
The panel can be customized based on specific testing requirements.
DLW follows strict sample integrity protocols, including:
→ Unique lab accession numbers for each specimen
→ Validity testing for pH levels, specific gravity, and creatinine
→ Screening for adulteration or dilution to ensure reliability
DLW uses a two-tiered testing approach for accurate results:
→ Screening Assays – Initial immunoassay screenings detect drug presence.
→ Confirmation Testing – Positive results undergo Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) for precise quantification.
UDT results are compiled into secure reports and provided to authorized parties such as:
→ Healthcare providers
→ Employers (as per workplace policies)
All results comply with privacy and confidentiality regulations.
Yes, DLW’s UDT can help healthcare providers:
→ Quantify drug levels in urine samples
→ Compare results with prescribed dosages
→ Detect potential drug misuse or abuse
To minimize false positives and negatives, DLW:
→ Uses LC-MS/MS confirmation testing for accurate drug quantification
→ Emphasizes strict sample collection and handling protocols
Yes, informed patient consent is required before conducting UDT, ensuring:
→ Ethical compliance
→ Patient awareness and transparency
DLW is committed to fast and accurate UDT results. Turnaround time varies based on:
→ Type of test conducted
→ Volume of samples processed
