Accredited Drug Testing offers comprehensive hair follicle drug assessments in Clinton, Maryland. Whether you're in need of a hair drug or alcohol test, our specialty truly lies in hair testing, with centers located in all cities across the Nation capable of conducting a hair analysis. Generally, 1.5 to 2 inches of hair from the head or body is required. Hair tests can detect drugs, alcohol/ETG, or other tailored options.

In recent times, the preference for hair follicle drug testing has grown. Numerous employers, legal entities, and Substance Abuse Experts are opting for hair drug tests over the more common urine tests. Employers with zero-tolerance policies, the courts, and probation individuals all utilize hair follicle drug tests. A significant advantage of this test is its extended drug detection window, typically up to 90 days, obtained through an observed process, making it nearly tamper-proof. However, for detection within 5 days, urine tests remain most precise.

What it is, How it works

Hair testing is recognized as an effective means for uncovering drug and alcohol consumption. The structure of hair captures biomarkers, providing a substantial chronological record of alcohol and various drugs within the fibers of the developing strand. Hair samples taken near the scalp can reveal substance usage for an estimated duration of up to three months. The collection process is straightforward, with minimal risk of tampering, and shipping is uncomplicated.

A 1.5-inch portion of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is optimal for screening and confirmation. For EtG, ancillary tests, or assessments beyond 10 panels, a recommendation of 150mg of the material is made. We advise measuring the sample on a jeweler’s scale. If scalp hair is not present, a similar volume of body hair can be used. The term head hair refers exclusively to scalp hair, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of integrating a sample into a lab’s framework. This step ensures the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.

Screening consists of a preliminary check for drugs of abuse. Although Screening is a cost-effective solution for ruling out drug use in most cases, a positive finding requires confirmation for legal admissibility. Any samples that test preliminarily positive must undergo secondary confirmation.

Presumptively positive samples in the Screening step involve further hair extraction for the Extraction phase. Here, drugs are removed from the hair at lower concentrations relative to other methods (e.g., urine or oral fluid), highlighting the complexity of performing hair drug testing.

Confirmation of any positive result from screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as needed. The complete lab process from Accessioning to Confirmation is audited according to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug use over a 90-day period, unlike urine tests which have shorter detection times.
  • Resistance to manipulation: The reliability of results is heightened, given the difficulty of compromising a hair drug test.
  • Historical consumption patterns: A timeline of drug use is accessible, covering an extended duration instead of merely recent usage.

Limitations:

  • Incapable of recent detection: Drugs become detectable in hair after approximately 5-7 days.
  • Expense: Hair drug tests incur a higher cost compared to alternative methods.
  • Result variability: Variables such as hair color and personal differences in hair growth impact drug metabolite concentration in the hair.

Note: Often labeled "hair follicle tests", this process evaluates the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Clinton, MD, surpasses traditional urine tests on multiple fronts. With superior detection capabilities, hair tests offer a refined analysis that urine tests often cannot match.
