Accredited Drug Testing provides comprehensive hair follicle drug evaluations in Oakhurst, California. If you're seeking a hair drug or alcohol analysis, we specialize in hair testing, with centers in cities across the nation. Generally, 1.5 to 2 inches of hair from the crown or body is required. Our hair analyses can detect drugs, alcohol/ETG, or be customized for other options.

In recent years, drug testing has increasingly integrated hair follicle evaluations. Numerous employers, courts, and Substance Abuse experts are opting for hair tests over traditional urine assessments. Used by employers with stringent anti-drug policies, judicial systems, and probation officers, one major advantage of hair testing is its extended detection timeframe, often reaching 90 days, with observed collection making it hard to falsify results. For recent drug use (within 5 days), however, urine tests remain the most precise.

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting substance use. Hair captures a comprehensive record of alcohol and drug consumption by embedding biomarkers within the strands as they grow. When sampled close to the scalp, hair can offer a detection period of up to roughly 90 days for alcohol and other drugs. Hair collection is straightforward, tamper-resistant, and simple to transport.

A sample measuring 1.5 inches, consisting of about 200 hairs (comparable to a #2 pencil in thickness), taken nearest to the scalp, results in 100mg of hair, which is optimal for both testing and confirmation. For EtG, additional tests, and/or panels over 10, a 150mg sample is advisable. It is suggested to weigh the sample with a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair can be collected. When discussing head hair, it exclusively refers to scalp hair. Body hair encompasses all other hair types (such as facial and axillary hair).

Process Overview

The drug test lab process includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial intake step for incorporating a sample into a laboratory's workflow. This involves confirming that the sample is properly sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplemental data required beyond what an electronic chain of custody system provides.

Screening serves as a preliminary examination for substances of abuse. Although Screening effectively eliminates drug use in most cases, a positive result must be validated to be court-acceptable. Samples that test positive during Screening must undergo secondary Confirmation.

For samples testing presumptively positive in Screening, additional hair from the initial sample undergoes preparation for Extraction. This step extracts drugs from hair at significantly lower concentrations than alternative methods (such as urine or oral fluids), making hair drug testing the most challenging technique to carry out.

GC/MS, GC/MS/MS, or LC/MS/MS methods verify positive results from Screening. Before Confirmation, presumptive positive samples undergo necessary washing. The complete laboratory sequence from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests identify drug usage for up to 90 days, as opposed to the limited window of urine tests.
  • Challenge to manipulate: The integrity of a hair drug test is challenging to compromise, enhancing result reliability.
  • Historical data provision: The tests divulge patterns of drug usage over time, not just recent activity.

Limitations:

  • Recent use detection is limited: Drugs are not detectable in hair for approximately 5-7 days.
  • Expense: Hair drug tests generally incur higher costs compared to other testing approaches.
  • Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite levels in hair.

Note: Though often called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing surpasses traditional urine tests substantially in Oakhurst, CA. The key advantage of hair testing lies in its superior detection accuracy and reliability, making it favored among employers. With hair tests, false negatives are minimized due to a longer detection window and reduced tampering risks, providing authentic results that urine tests may miss.

Extended Detection Window

Offering notable advantages, hair follicle testing in Oakhurst, CA, extends the detection timeline of substances up to 90 days. This extended window enables employers to obtain a detailed overview of an individual's substance history, enhancing decision-making regarding hiring or continued employment. Such a comprehensive view of drug use history outmatches the typically shorter timeframes of other tests.
