In Mammoth Lakes, CA and across the country, urine drug testing is the most widely utilized screening method and is the exclusive test type sanctioned for DOT-regulated drug testing under 49 CFR Part 40. By evaluating a urine sample for drugs, drug by-products, or alcohol markers, recent substance use can be detected. This standardized and confidential procedure ensures the delivery of precise, legally rigorous results for employers, individuals, and legally ordered programs.
Testing Methods & Collection Process
1. Donor Identity Verification
The donor must present a legitimate government-issued ID and complete the necessary chain-of-custody signatures before initiation of testing.
2. Secure Collection Environment
Urine samples are collected in secured restroom facilities to deter tampering, often involving restrictions on personal belongings, securing water sources, and dyeing toilet water as part of security norms.
3. Chain of Custody Documentation
A federally endorsed Chain of Custody Form (CCF) meticulously tracks the sample's journey from collection through to laboratory analysis, preserving the test's integrity and legal viability.
4. Temperature & Validity Checks
Post-collection, the specimen is scrutinized for temperature and appearance accuracy. Additionally, validity testing including checks for creatinine levels, pH, specific gravity, and adulterant presence is conducted.
5. DOT Split Specimen
DOT urine tests involve bifurcation into two vials: Bottle A is utilized for primary analysis and Bottle B for retesting in case of a challenge. For non-DOT tests, a single vial is collected.
6. Laboratory Screening & Confirmation
Samples are processed in SAMHSA-certified laboratories through a dual-step process:
7. MRO Verification
Non-negative results are substantiated by a licensed Medical Review Officer (MRO), who validates the data and discusses any possible medical justifications with the donor prior to final result dissemination.
Additional processing time may be necessary for situations involving shy bladders, invalid samples, or where lab validation and donor interaction are essential.
Limitations of Urine Drug & Alcohol Testing
Despite these limitations, urine tests remain the leading choice for drug and alcohol detection across the nation.
In Mammoth Lakes, CA and beyond, hair drug and alcohol testing serves as a highly consistent laboratory method to reveal long-term substance use patterns. Unlike urine testing focused on recent intoxication, hair testing provides a 90-day insight by assessing drug metabolites embedded within the hair strands. This method is especially beneficial for workplace screening, legal inquiries, child custody cases, and any context demanding a comprehensive view of a person's substance use antecedents.
Testing Methods & Collection Process
1. Donor Identity Verification
The process initiates with the donor showing a valid government ID, followed by the completion of consent and chain-of-custody documents to affirm authentic documentation.
2. Hair Collection Procedure
At collection, a trained professional acquires a minor hair sample, typically comprising 100-120 strands near the scalp. Should scalp hair be unavailable, body hair is an alternative. This immediate, painless procedure occurs under direct oversight.
3. Chain of Custody Documentation
Documentation with a Hair Drug Test Custody and Control Form logs the specimen's acquisition, sealing, and transfer to uphold legality and protect the results during testing.
4. Laboratory Preparation & Analysis
Upon reaching the lab, the hair specimen undergoes comprehensive forensic processes, including:
Following extraction, samples undergo detailed lab testing:
5. Metabolite Detection
Metabolites, trapped within the hair as it grows, offer a stable, enduring record of substance use. Given these internal incorporations, falsifying results or cheating is extremely arduous.
6. MRO Review
Certified Medical Review Officers evaluate non-negative outcomes, confirming test accuracy and scrutinizing possible medical explanations before finalizing the conclusive results.
How Long Do Hair Test Results Take?
Hair testing's multi-layered lab process implies a marginally extended turnaround than urine testing, yet ensures unparalleled detection constancy.
Limitations of Hair Drug & Alcohol Testing
Regardless of these limitations, hair testing remains a notable method for verifying long-term substance use, leveraged broadly by employers, legal authorities, and individuals seeking credible, tamper-resistant findings.
At Accredited Drug Testing, we present a diverse array of drug and alcohol screening strategies, each tailored to meet the demands of employers, Department of Transportation (DOT) prescriptions, legal requirements, and personal evaluations.

Our extensive network, certified labs, and skilled Medical Review Officers uphold the precision, credibility, and professionalism crucial for results you can count on.
The alcohol urine test is designed to detect recent alcohol intake by tracking ethanol metabolites in the urine. This technique is frequently deployed for workplace testing, court mandates, and following accidents. Although it doesn't measure current impairment, it extends a window of detection for several hours, rendering it a rapid and cost-effective option for monitoring.
The EtG (Ethyl Glucuronide) urine test offers highly sensitive screening to catch alcohol consumption up to 80 hours post-intake. Due to EtG being a direct digested form of ethanol, this test is ideal for judicial systems, rehabilitation centers, and monitoring bodies. It spans a longer detection window than conventional urine tests and is celebrated for reliability and accuracy.
A breath alcohol test determines current intoxication levels by evaluating the alcohol percentage in deep lung air. Utilized with DOT-certified breath alcohol devices (EBTs), it provides immediate and defensible outcomes. This procedure is mandated for DOT-involved staff and commonly employed for workplace checks, accidents, and suspicious behavior cases.
The blood alcohol test directly quantifies the ethanol concentration in the bloodstream, representing one of the most precise methods for assessing impairment. Trusted by hospitals, law enforcement, and legal experts, blood alcohol tests are pivotal for DUI situations, emergency scenarios, and high-stakes legal investigations.
A PEth (Phosphatidylethanol) blood test identifies habitual or excessive alcohol consumption by detecting biomarkers in red blood cells. Capturing intake up to 2-3 weeks, PEth provides a robust indication of ongoing drinking behavior, invaluable in family law, monitoring regimens, rehabilitation facilities, and pre-employment protocols for safety-focused domains.
The EtG hair alcohol test spans an expansive 90-day detection period through assessment of alcohol derivatives in hair strands. This technique tracks extensive patterns signifying regular or historical alcohol use instead of isolated consumption instances. Preferred by courts, child custody deliberations, and enduring surveillance schemes for its dependability and precision.
With experienced oversight, accredited laboratories on a national scale, and efficient scheduling, Accredited Drug Testing ensures that each alcohol assessment procedure offers defensible, transparent, and compliant insights, supporting individuals and organizations in maintaining awareness, security, and adhering to regulation rigorosities.
