Hair Follicle Drug Testing - Clarendon, AR

What it is, How it works

Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the hair strand's fibers as it grows. When collected near the scalp, hair samples can offer a detection period of up to roughly 3 months for alcohol and other substances. Hair collection is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (comparable in size to a #2 pencil) closest to the scalp provides 100mg of hair, which is the ideal amount for both screening and confirmation. For EtG add-ons, and/or when testing beyond 10 panels, it is advisable to collect 150mg of the sample. We suggest using a jeweler's scale for weighing the sample. If scalp hair cannot be obtained, an equivalent amount of body hair may be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test result involves four key procedures: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of the sample into the laboratory's system. This step includes verifying the integrity of the sample's seal and shipment, assigning a Laboratory Accessioning Number (LAN) at random, and concluding any additional data entry not facilitated by an electronic chain of custody system.

Screening provides a preliminary overview for substances of abuse. While a cost-efficient method to dismiss drug usage in most cases, a positive screening must be confirmed for legal admissibility. Any samples that presumptively test positive during Screening require further confirmation.

If a sample shows presumptive positivity during Screening, additional hair is extracted from the original sample and prepared for Extraction. During this stage, substances are isolated from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screenings.

Confirmation of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation, as deemed necessary. The comprehensive laboratory process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, in contrast to urine tests which have a more limited detection timeline.
• Hard to manipulate: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Chronological insight: It offers a timeline of drug use across time frames, not merely recent consumption.

Limitations:

• Inability to detect immediate use: There is a latency of around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are generally more costly than alternative drug testing methods.
• Variability in outcomes: Aspects such as hair color and personal differences in hair growth can influence the presence of drug metabolites in hair.

Note: Although often called "hair follicle tests", the analysis focuses on the hair strand and not the hair follicle beneath 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.
