Hair Follicle Drug Testing - Langley, AR

What it is, How it works

Testing hair is now recognized as a potent method for uncovering alcohol and drug consumption. Hair captures long-term evidence of drug and alcohol use by embedding biomarkers in its fiber strands. When sourced near the scalp, hair samples offer around a 3-month detection span for various substances. Hair collection is straightforward, its tampering is relatively challenging, and transport is uncomplicated.

An ideal hair sample size for screening and confirmation is a 1.5-inch section containing about 200 strands (equivalent to a #2 pencil thickness) near the scalp to obtain 100mg of hair. For EtG tests, additional testing, or panels exceeding 10, a 150mg specimen is advised. Using a jeweler's scale is suggested for weighing the sample. Should scalp hair be unavailable, an equivalent amount of body hair is permissible. References to head hair specify scalp hair exclusively, whereas body hair encompasses other types (such as facial or axillary hair).

Process Overview

The laboratory's processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is incorporated into a laboratory's system. It involves confirming the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any unprovided electronic chain of custody data entries.

Screening encompasses a swift preliminary check for drug abuse. Although Screening provides a cost-beneficial approach to rule out drug use among most samples, legal admission necessitates that a positive screen undergo confirmation. Presumptive positive samples in Screening call for secondary confirmation.

When a sample tests presumptively positive during Screening, additional hair is taken from the initial sample for Extraction. During Extraction, drugs are derived from hair at considerably reduced concentrations compared to other methods (e.g., urine or oral fluid), establishing hair drug screening as challenging to execute.

Presumptive positive screenings undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are given a wash prior to confirmation if necessary. From Accessioning through to Confirmation, each process aspect is scrutinized under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Drug use is traceable in hair for up to 90 days, surpassing the shorter window provided by urine tests.
• Difficult to tamper: Cheating on a hair drug test is notably challenging, enhancing result precision.
• Historical data availability: It reveals drug use tendencies over time rather than merely recent usage.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days before becoming traceable in hair.
• Cost implication: Hair drug tests tend to be pricier than other methods.
• Result variations: Disparities like hair color and individual hair growth can impact drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests", the examination focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Langley, AR, hair follicle testing has distinct advantages over traditional urine tests. One primary benefit is its extended detection period. While urine tests identify recent substance use, hair follicle tests offer insights into drug use over the past 90 days. This provides a more comprehensive view of an individual's history.

Furthermore, hair tests are nearly impossible to compromise, offering unmatched reliability. Employers and courts favor hair analysis for its precision and resilience against tampering, making it a superior choice in maintaining drug-free environments.
