Urine drug testing reigns as the most popular screening technique throughout La Puente, CA, and indeed, the nation. Serving as the exclusive method sanctioned for DOT-regulated drug testing, this test is conducted in accordance with 49 CFR Part 40 guidelines. By examining a urine sample, this method detects recent consumption of drugs, drug metabolites, or alcohol biomarkers, ensuring a thorough and confidential screening while delivering legally defensible results that are crucial for employers, individuals, and court-ordered programs.
Testing Methods & Collection Process
1. Donor Identity Verification
The procedure commences with the donor presenting an authorized government identification and signing the necessary chain-of-custody form.
2. Secure Collection Environment
Specimens are collected in a controlled setting, securing all water sources and sometimes dying the toilet water, to mitigate any tampering risks and uphold the sample's integrity.
3. Chain of Custody Documentation
A Chain of Custody Form (CCF) is utilized, following the specimen from its collection to the laboratory, ensuring the test's credibility and defensibility.
4. Temperature & Validity Checks
Post-collection, the collector evaluates the specimen's temperature and appearance. Laboratory analyses include validity testing through parameters such as creatinine levels, pH, specific gravity, and adulterant screenings.
5. DOT Split Specimen
For DOT tests, the specimen is divided into Bottle A for primary screening and Bottle B reserved for retesting if initial results are contested. Non-DOT tests generally collect a single sample.
6. Laboratory Screening & Confirmation
7. MRO Verification
A qualified Medical Review Officer (MRO) evaluates any non-negative results, confirming them before releasing the official results.

An alcohol urine test spots recent alcohol intake by assessing ethanol metabolites within urine. Often employed for workplaces, legal trials, and post-incident investigations, it provides a brief detection window of several hours, although it does not gauge current impairment. This renders it a swift, economical choice for screening needs.
The EtG (Ethyl Glucuronide) urine test reveals alcohol consumption up to 80 hours post-ingestion. Being a precise ethanol metabolite, the EtG test is preferred by courts and rehabilitation entities for its extended detection period over traditional tests.
A breath alcohol test examines deep lung air for a real-time assessment of impairment. Using DOT-certified breath analyzers (EBTs), these tests afford immediate, legally defensible results, making them standard for DOT-enlisted employees and used frequently for corporate, post-incident, and justifiable suspicion testing.
The blood alcohol test precisely measures ethanol presence in the blood, recognized for its accuracy, especially in DUI, emergency care, and intensive judicial inquiries due to its provision of precise impairment measures.
The PEth (Phosphatidylethanol) blood test identifies enduring alcohol intake patterns more accurately by isolating alcohol-specific biomarkers in red blood cells, providing strong evidence of sustained consumption over 2-3 weeks and frequently engaged in family law, assessment centers, and safety-sensitive employment screenings.
The EtG hair alcohol test delivers a 90-day lookout for repeated or chronic alcohol use by identifying metabolites in hair strands, often relied upon in judicial contexts and long-term monitoring schemes.
