Accredited Drug Testing offers comprehensive hair follicle drug screening services in Oakland, Missouri. Whether you need a drug or alcohol hair test, our facilities, located across various cities nationwide, are equipped to conduct such tests. Typically, 1.5 to 2 inches of hair from the crown or body is needed. Hair analysis can include drugs, alcohol/ETG, or other specific options.

Recently, hair follicle drug tests have become more prevalent in drug testing. Employers, courts, and substance abuse experts increasingly favor hair tests over traditional urine tests. These tests suit employers with zero-tolerance policies, judicial settings, and those on probation. The chief advantage of hair testing is its extended detection window, up to 90 days, with supervised collection, making cheating almost impossible. However, for detecting recent drug use within five days, urine testing remains the best option.

What it is, How it works

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair strands capture biomarkers within the curls of developing hair, offering a prolonged history of drug and alcohol intake. Gathering hair samples near the scalp can yield an approximately 90-day observation period for detecting drugs and alcohol. The simplicity of gathering hair, its resilience against tampering, and ease of transport are notable advantages.

Securing a 1.5-inch length of roughly 200 hair strands (comparable to the diameter of a #2 pencil) closest to the scalp extracts 100mg of hair, which is an optimal quantity for assessments and validation. For EtG, supplementary tests, and/or those exceeding 10 panels, a recommendation of 150mg of the sample is advisable. Employing a jeweler’s scale for accuracy is suggested. If head hair is not available, a similar quantity of body hair is an alternative. The term "head hair" exclusively indicates scalp hair, whereas "body hair" includes all other hair categories (facial, axillary, etc.).

Procedure Outline

The core stages in processing a laboratory drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary entry of a sample into a laboratory’s system. It verifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and addresses any further data input not covered by an electronic chain of custody protocol.

Screening provides an initial, efficient evaluation for substance misuse. This phase is economically efficient for eliminating drug use in most samples, yet results necessitating courtroom acceptance must undergo Confirmation. Any samples flagged as potentially positive during Screening require secondary confirmation.

Should a sample register as potentially positive in the Screening phase, additional hair is detached from the original sample and readied for Extraction. In this step, drugs are derived from hair at a significantly lower concentration compared to other methods (i.e., urine or oral fluid), underscoring the complexity involved in hair drug screenings.

Validation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples are cleansed in preparation for Confirmation, as required. The comprehensive laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and the endorsement of ISO / IEC 17025 standards.

Benefits of hair drug testing:

  • Extended detection period: Hair drug assays can identify drug use over a 90-day span, in contrast to urine tests with a more limited detection period.
  • Hard to tamper: Cheating on a hair drug test is highly challenging, enhancing result accuracy.
  • Chronological data provision: Offers a drug use pattern over time rather than merely reflecting recent usage.

Drawbacks:

  • Inability to reveal recent use: A timeframe of about 5-7 days is required for drug traces to become evident in hair.
  • Expense: Hair drug examinations are typically costlier than other testing approaches.
  • Result variability: Parameters such as hair pigmentation and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: The term "hair follicle tests" often used is misleading, as the actual analysis focuses on the hair shaft, not the follicle beneath the scalp.
