Hair Follicle Drug Testing - Saint Landry, LA

What it is, How it works

The utilization of hair testing has emerged as an influential method for identifying alcohol and drug consumption. Hair captures a comprehensive timeline of substance intake by embedding biomarkers within the hair strands as they grow. When sampled near the scalp, hair can offer around a three-month retrospective analysis for both alcohol and other drugs. Hair sampling is straightforward to procure, comparably resistant to tampering, and simple to transport.

An optimal sample involves collecting 1.5 inches of hair—amounting to around 200 strands or the thickness of a #2 pencil—near the scalp, providing 100mg of hair, ideal for both preliminary testing and subsequent confirmation. For tests involving EtG, add-ons, or those surpassing 10 panels, a 150mg specimen is advised. It is beneficial to weigh the sample using a jeweler’s scale. If scalp hair is not procurable, an equivalent amount of body hair is acceptable. References to head hair strictly denote scalp hair, while body hair encompasses other types such as facial or axillary.

Process Overview

There are four crucial phases in the laboratory processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen into the lab's database. This encompasses ensuring the sample is suitably sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and completing any data entry absent in an electronic chain of custody record.

Screening provides an initial assessment for drug abuse. While economical to rule out drug use in most samples, a positive outcome necessitates confirmation for courtroom admissibility. Any samples yielding presumptive positives during Screening require secondary confirmation.

In instances of presumptive positives during Screening, additional hair is obtained from the original sample for the Extraction stage. Here, substances are extracted from the hair at lesser concentrations than noted in methods like urinalysis or oral swabs, highlighting why hair drug testing is particularly complex to execute.

Confirmation of all positive results from screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Prior to confirmation, any samples with presumptive positives are cleansed as required. The comprehensive laboratory protocol from Accessioning through Confirmation receives review under the CAP (College of American Pathologists) Hair criteria and adheres to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify usage for a duration of up to 90 days, contrasting with urine tests which have a more limited timeframe.
• Resistant to adulteration: The integrity of hair drug tests is challenging to compromise, thereby ensuring more precise outcomes.
• Reveals consumption patterns: It can illustrate a history of substance use over a span of time, unlike tests that only identify recent usage.

Limitations:

• Inability to detect recent consumption: Drugs typically become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests often entail higher costs compared to other methods.
• Result variability: Elements such as hair color and individual idiosyncrasies in hair growth can influence drug metabolite levels in hair.

Note: Though termed "hair follicle tests", the actual analysis focuses on the hair strand, not the follicle under the scalp.
