Hair Follicle Drug Testing - Northcliff, TX

What it is, How it works

Hair testing is increasingly acknowledged as a robust method to detect drug and alcohol consumption. Hair retains evidence of alcohol and drug use over time by embedding biomarkers within the strands as they grow. When hair is collected near the scalp, it can offer a detection timeframe of up to roughly three months for drugs and alcohol. The process of obtaining hair samples is straightforward, they are less likely to be tampered with, and they are simple to transport.

A 1.5-inch section comprising around 200 hair strands (approximately the girth of a #2 pencil) taken from the scalp provides about 100 mg, the preferred quantity for screening and validation. For EtG, add-ons, or tests exceeding 10 panels, a 150 mg sample is advisable. Using a jeweler’s scale is suggested for weighing the sample. If scalp hair is not accessible, a comparable amount of body hair can be sourced. Regarding head hair, it specifies scalp hair only. Body hair denotes all remaining hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into the laboratory's system, confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not covered by an electronic chain of custody system.

Screening represents a preliminary assessment for drug use. Although screening is a cost-effective measure to exclude drug use in most samples, any positive findings from this stage must be confirmed to stand legal scrutiny. Any samples yielding a presumptive positive during screening necessitate further confirmation.

Upon a presumptively positive result in the Screening phase, additional hair is extracted from the original sample for the Extraction process. This phase extracts drugs from hair at considerably lower concentrations than other techniques (such as urine or oral fluid), making hair drug screening notably challenging.

Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation if needed. The complete process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests that have a much shorter detection window.
• Hard to manipulate results: Cheating a hair drug test is highly challenging, thus enhancing result accuracy.
• Historic usage data available: This test can reveal a pattern of drug use over a span of time, not just recent consumption.

Limitations:

• Recent use undetected: It requires roughly 5 to 7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variations: Influences such as hair color and personal differences in hair growth can alter the drug metabolite concentration in hair.

Note: Even though commonly referred to as "hair follicle tests," the analysis focuses on the hair strand, not the hair follicle below the scalp.

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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
