Hair Follicle Drug Testing - England, AR

What it is, How it works

Hair analysis has emerged as an effective means for identifying the use of drugs and alcohol. It provides a comprehensive history of substance intake by capturing biomarkers within the fibers of a hair strand as it grows. When sourced close to the scalp, hair extends a detection window for substances, like alcohol or drugs, lasting up to about three months. Hair collection is straightforward, relatively resistant to tampering, and conveniently shippable.

An optimal sample consists of a 1.5-inch segment with around 200 hair strands (comparable in size to a #2 pencil), yielding 100mg of hair, suitable for both screening and confirmation. For procedures involving EtG, add-ons, and/or more than 10 panels, 150mg of the sample is recommended. It's advisable to weigh samples using a jeweler’s scale. In cases where scalp hair is inaccessible, equivalently, body hair may be used. Head hair refers specifically to scalp hair, whereas body hair includes all other types (e.g., facial, axillary, etc.).

Process Overview

Primary stages in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial integration of a sample into a laboratory's system. This process ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry omitted by electronic chain of custody systems.

Screening involves a preliminary assessment for illicit substances. While it is a cost-saving method for excluding drug use in most samples, a positive outcome requires confirmation to hold weight in legal settings. Samples indicating a presumptive positive during Screening necessitate a secondary verification.

If a sample yields a presumptive positive result in Screening, additional hair is extracted for further Processing. During this stage, drugs are isolated from the hair at much lower concentrations compared to methods like urine or oral fluid testing, making hair drug screening one of the more challenging methodologies to conduct.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo necessary washing before confirmation. The full laboratory procedure from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can reveal drug use for as long as 90 days, while urine tests offer a more limited detection period.
• Resistance to tampering: Due to the difficulty in adulterating hair specimens, results are more reliable.
• Historical data provision: Offers a usage pattern over time rather than just recent activity.

Limitations:

• Inability to detect recent usage: Drug presence in hair becomes detectable around 5-7 days post-consumption.
• Expense: Hair drug tests tend to be costlier than alternative drug testing methods.
• Result inconsistency: Variables like hair color and differential hair growth may influence metabolite concentration levels within the hair.

Note: Despite commonly being called "hair follicle tests," the test examines the hair strand, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in England, AR In England, AR, the choice between hair follicle and urine testing is clear for many. Hair testing offers superior detection accuracy and reliability, making it the preferred method for comprehensive screenings.
