Hair Follicle Drug Testing - Indian Village, LA

What it is, How it works

Hair testing is recognized as an effective means for detecting substance use. It provides a comprehensive historical record of alcohol and drug intake by capturing biomarkers within the growing hair strand. If collected near the scalp, hair can reveal drug and alcohol consumption over roughly a three-month duration. This method is straightforward in terms of collection, challenging to tamper with, and convenient to transport.

A sample of 1.5 inches, consisting of approximately 200 hair strands (resembling the thickness of a number 2 pencil) near the scalp, yields the ideal 100mg amount for analysis and confirmation purposes. For tests involving EtG, additional substances, or exceeding 10 panels, a 150mg sample is preferable. The sample should ideally be measured on a jeweler’s scale. Should scalp hair be inaccessible, a comparable portion of body hair may be gathered. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (e.g., facial, axillary).

Process Overview

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

Accessioning involves incorporating a sample into the lab systems. This step includes ensuring the sample is sealed and dispatched correctly, assigning a distinct LAN (Laboratory Accessioning Number), and completing any further data entry absent in an electronic chain of custody.

Screening is a preliminary swift assessment for any drugs of abuse. It serves as a cost-efficient method to dismiss drug use in most samples, however, positive results require confirmation for legal acceptability. Samples indicating drug presence after screening necessitate a subsequent confirmation.

During the Extraction phase, should a screen indicate drug presence, further hair is allocated for processing. Hair drug screening demands drugs to be extracted at significantly lower concentrations than alternate methods (e.g., urine or oral fluid), making it a notably challenging technique.

Confirmation of positive results occurs via GC/MS, GC/MS/MS, or LC/MS/MS. If needed, samples indicating drug presence are cleansed before confirmation. Every step from Accessioning to Confirmation is evaluated in compliance with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Unlike urine tests with limited detection capacity, hair drug tests can identify drug use for up to 90 days.
• Resistance to manipulation: The challenging nature of cheating a hair drug test renders the results very reliable.
• Provision of historical patterns: It showcases a timeline of drug consumption, encompassing more than just recent intake.

Limitations:

• Inability to indicate recent usage: Detectability in hair requires approximately 5-7 days post-drug intake.
• Expense: Generally, hair drug tests entail greater costs compared to other methodologies.
• Result variability: Factors such as individual hair color and growth rates can impact drug metabolite concentration in hair.

Note: While commonly labeled as "hair follicle tests", the methodology assesses the hair strand, not the follicle beneath the scalp.
