Hair Follicle Drug Testing - Cornish, OK

What it is, How it works

Hair testing has emerged as a valuable resource for identifying drug and alcohol usage. Hair offers an extended history of alcohol and drug consumption by locking biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair stands capable of delivering a detection window for alcohol and drugs of up to roughly 3 months. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a sample of 150mg is advised. It is beneficial to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair might be used. When head hair is mentioned, it refers exclusively to scalp hair. Body hair includes all other hair varieties (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial processing of a sample within a laboratory’s framework. This step covers ensuring the sample was securely sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry needed beyond what is provided by an electronic chain of custody system.

Screening involves a preliminary swift evaluation for substances of abuse. Although Screening is an economical method to eliminate drug use in most samples, a positive screen requires confirmation to hold up in court. Any samples showing presumptive positives in Screening need to undergo a secondary verification process.

In instances where a sample appears presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are drawn from hair at a concentration level significantly lower than other methods (for example, urine or oral fluid), underscoring the challenge of executing hair drug screening.

Verification of any positive screening outcomes is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive necessary washes prior to confirmation. The whole laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug assessments can identify drug use for periods extending up to 90 days, contrasting with urine tests which offer a shorter detection span.
• Difficult to compromise: Cheating a hair drug test is exceedingly tough, contributing to enhanced accuracy in results.
• Offers historic insight: It can highlight a pattern of drug use over time, rather than merely recent usage.

Limitations:

• Incapable of detecting recent consumption: A span of approximately 5-7 days is required before drugs become evident in hair.
• Expense: Hair drug assessments generally incur higher costs than other drug testing methods.
• Result variability: Aspects like hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: Typically referenced as "hair follicle tests," the test itself examines the hair strand rather than the follicle located beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
