Hair Follicle Drug Testing - Humboldt, TN

What it is, How it works

Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drugs by locking biomarkers within the hair strand's growing fibers. When gathered near the scalp, it can indicate alcohol and drug use over a timeline of up to roughly 3 months. The collection of hair is straightforward, relatively tough to tamper with, and convenient to transport.

A 1.5-inch segment consisting of around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal sample for analysis and validation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It is advised to gauge the specimen using a jeweler’s scale. Should scalp hair be lacking, an equivalent volume of body hair may be used. By head hair, we mean scalp hair exclusively. Body hair includes all other types of body hair (face, underarms, etc.).

Process Overview

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

Accessioning is the preliminary processing of the specimen into a lab’s system. This process ensures the sample was tightly sealed and appropriately shipped, allocates a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from an electronic chain of custody system.

Screening is a primary rapid assessment for drugs of abuse. Screening offers a cost-efficient way to dismiss drug use in the majority of samples, however, a positive screening necessitates being confirmed to be court-admissible. Presumptively positive Screening samples demand subsequent confirmation.

Upon a sample showing presumptive positivity in the Screening phase, more hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at far lower concentrations than alternative methods (i.e., urine or oral fluid), making hair drug testing a notably challenging methodology.

Confirmation of a positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing, as necessary, before final confirmation. The complete laboratory process from Accessioning through Confirmation is scrutinized per both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can detect drug use up to 90 days, unlike urine evaluations that have a more limited detection span.
• Challenging to falsify: Cheating a hair drug test is exceedingly hard, lending more validity to results.
• Yields historical context: It can depict a trend of drug usage over time, rather than just immediate usage.

Limitations:

• Cannot trace recent consumption: A period of about 5-7 days is necessary for drugs to become detectable in hair.
• Expense: Hair drug evaluations typically cost more than other testing approaches.
• Result variations: Elements such as hair color and unique hair growth differences can impact the level of drug metabolites in hair.

Note: Often termed "hair follicle tests", this assessment actually evaluates the hair strand, not the hair follicle beneath the scalp.
