Hair Follicle Drug Testing - Innis, LA

What it is, How it works

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a longitudinal record of alcohol and other substance use by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, hair may offer a detection window of up to roughly 3 months for alcohol and other drugs. Collecting hair is straightforward, relatively tamper-resistant, and simple to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (around the diameter of a #2 pencil) from nearest the scalp will yield 100mg of hair, which is optimal for both screening and confirmation purposes. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg specimen is advised. It is recommended to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, a comparable volume of body hair may be taken. Scalp hair refers specifically to head hair, while body hair encompasses all other varieties (e.g., facial, axillary, etc.).

Process Overview

The drug test result processing in the lab involves four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary processing of a sample within a lab’s framework. This step ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry missing from an electronic chain of custody system.

Screening serves as an initial swift evaluation for substances of abuse. Although cost-effective for excluding drug presence in the majority of samples, a positive screen needs to be validated to be admissible legally. Any samples showing a presumptive positive during Screening necessitate a subsequent confirmation.

If Screening yields a presumptive positive, additional hair is extracted from the initial sample and readied for Extraction. During this stage, drugs are isolated from hair at much lower concentrations in comparison to alternative methods (like urine or oral fluid), thus making hair drug screening a demanding method to execute.

The confirmation step for any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo a cleansing before confirmation if necessary. The complete lab process from Accessioning to Confirmation undergoes evaluation by the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can reveal drug use spanning up to 90 days, unlike urine tests which offer a brief detection time frame.
• Hard to falsify: Manipulating hair drug tests is exceedingly difficult, enhancing result precision.
• Delivers historical insight: It can illustrate a pattern of substance use over time, instead of merely current use.

Limitations:

• Incapable of identifying immediate use: Detection of drugs in hair requires about 5-7 days.
• Expense: Hair drug tests typically incur higher costs compared to alternative testing techniques.
• Result variability: Attributes such as hair color and personal variations in hair growth could influence drug metabolite concentrations within hair.

Note: Often termed as "hair follicle tests", this test actually examines the hair strand, not the follicle beneath the scalp.
