Urine drug testing is the most prevalent method for screenings, widely recognized nationwide, and the sole type approved for DOT-regulated drug tests in accordance with 49 CFR Part 40. This approach evaluates a urine sample to identify recent drug use, alcohol markers, or metabolites. The process is confidential, streamlined, and designed to produce legally defensible outcomes for employers, individuals, and judicial mandates.
Testing Methods & Collection Process
1. Donor Identity Verification
The donor furnishes legitimate government-issued identification and completes necessary chain-of-custody documentation before testing commencement.
2. Secure Collection Environment
Specimens are gathered in a controlled restroom setting, protecting the integrity of the test. Items may be restricted, water secured, and toilets dyed as part of security protocols.
3. Chain of Custody Documentation
A federally sanctioned Chain of Custody Form (CCF) ensures sample integrity from collection through laboratory analysis.
4. Temperature & Validity Checks
Post-collection, the specimen's temperature and appearance are validated. The laboratory conducts additional tests for validity, checking creatinine levels, pH, and specific gravity.
5. DOT Split Specimen
DOT urine samples are divided into two Bottle A for primary analysis and Bottle B for a retest if contested. For non-DOT tests, only one vial is collected.
6. Laboratory Screening & Confirmation
At SAMHSA-certified labs, samples undergo two-step analysis:
7. MRO Verification
A Medical Review Officer examines non-negative results, assessing potential medical explanations with the donor before finalizing.
Additional time may be necessary in cases like shy bladder or for further confirmation needs.
Limitations of Urine Drug & Alcohol Testing
Despite some limitations, urine testing is vital and remains a common choice nationwide.
Hair testing serves as a sophisticated and precise approach to discerning long-term substance usage patterns. Unlike urine testing, which captures recent consumption, hair drug screening affords a comprehensive 90-day detection window by examining metabolites integrated within hair shafts, rendering it ideal for employment programs, legal matters, custody disputes, and other engagements necessitating an extensive view of one's substance history.
Detailed Testing Procedures & Collection Process
1. Donor Identity Confirmation: Initiating the collection involves presenting a confirmed government-issued ID and finalizing any relevant consent forms and chain-of-custody documentation.
2. Hair Sample Collection: A trained professional extracts a small sample, typically around 100-120 strands, preferably from the crown to maintain discretion. Absence of scalp hair prompts the collection of body hair. This procedure is swift, straightforward, and carefully supervised.
3. Chain of Custody Documentation: The Hair Drug Test Custody and Control Form meticulously records the collection, sealing, and transfer processes to maintain the sample's legal standing.
4. Laboratory Processing & Analysis: Collected samples undergo a regimented forensic procedure at the lab:
Following preparation, the sample undergoes detailed lab testing:
5. Metabolite Detection: As hair grows, metabolites are trapped inside the shaft, providing a durable long-term record difficult to alter or destroy.
6. Review by Medical Review Officer: MROs verify non-negative results, assessing the accuracy and identifying valid medical causes before issuing official results.
While the process is slightly prolonged compared to other methods, the stability and reliability ensure the robustness of results.
Despite certain limitations, hair drug testing presents an uncompromised methodology for assessing substance use over the long term, affording a reliable resource for legal and personal assessments throughout Woodland, CA.

The alcohol urine test detects short-term alcohol ingestion by identifying ethanol metabolites present in urine. Frequently employed for workplace evaluations, judicial adherence, and post-incident assessments, it does not indicate current intoxication but offers a brief detection span of several hours, making it a rapid and budget-friendly choice.
The EtG (Ethyl Glucuronide) urine screening is an advanced methodology capable of detecting alcohol usage up to 80 hours following ingestion. As a direct ethanol metabolite, it is extensively used by Woodland, CA courts, recovery initiatives, and compliance groups for its extended detection timeline and absolute precision.
A breath alcohol examination measures current intoxication by determining alcohol levels in breath from deep lung air. Using DOT-compliant breathalyzer devices (EBTs), these tests offer instant, legally viable results and are mandated for employees under DOT oversight, besides being widely used in workplaces or suspicion-based searches.
The blood alcohol measurement reflects ethanol circulation in the bloodstream, offering unmatched accuracy to measure intoxication levels. Hospitals, law enforcement, and legal professionals lean on blood alcohol evaluations, particularly in Woodland, CA DUI cases and emergency situations.
A PEth (Phosphatidylethanol) blood test identifies prolonged alcohol intake by revealing alcohol-associated biomarkers within red blood cells. It tracks consumption within a 2-3 week window, recognized for depicting long-term drinking tendencies crucial in legal contexts and safety-driven employment screening.
The EtG hair analysis extends detection to a 90-day timeframe by analyzing metabolites ingrained in the hair shaft, ideal for monitoring repetitive or sustained alcohol use. Legal entities often depend on this test for its robustness and resilience against transitional abstinence.

Time was running out before my Cdl got downgraded because of a violation I had on clearinghouse. I couldn't find an employer to send me for my return to duty test, but these guys had my test scheduled and done in the same day! They saved my cdl. Thank you again!

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
