Hair Follicle Drug Testing - Red Oak, LA

What it is, How it works

Hair testing is increasingly recognized as an effective method for tracing drug and alcohol usage. Hair traps biomarkers within the strands as it grows, providing a longer-term record of substance use. Collecting hair near the scalp yields a detection window of up to three months for substances like alcohol or other drugs. Collecting hair is straightforward, with minimal risk of tampering, and it is easy to transport.

To obtain a suitable sample, cut 1.5 inches of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp, resulting in 100mg of hair, the perfect amount for screening and confirmation. For tests such as EtG or those exceeding 10 panels, 150mg is advised. Using a jeweler’s scale for accuracy is recommended. If scalp hair is not accessible, a similar quantity of body hair may be used. It is important to note that head hair specifically means scalp hair, while body hair encompasses all other types of hair (such as facial and axillary).

Process Overview

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

Accessioning is the initial step, where a sample is introduced into a lab’s system. This phase includes confirming proper sealing and shipment of the sample, generating a unique LAN (Laboratory Accessioning Number), and processing any additional necessary data if an electronic chain of custody system doesn’t provide it.

Screening provides a preliminary assessment for drug presence. Though cost-effective in excluding drug use in many samples, a positive screen necessitates confirmation for legal proceedings. Samples that are initially positive in Screening must undergo further confirmation.

A sample deemed positive in the Screening requires additional hair from the primary specimen for Extraction. In this phase, drugs are extracted from the hair at much lower levels than methods like urine or oral fluid, making hair drug screening notably challenging.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumed positive outcomes are cleaned before Confirmation as necessary. Every aspect of the process, from Accessioning to Confirmation, is scrutinized under both CAP (College of American Pathologists) hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection duration: While urine tests offer a shorter detection span, hair drug tests can trace drug usage for as long as 90 days.
• Hard to manipulate: Since it’s extremely difficult to falsify a hair drug test, the test results are more reliable.
• Shows usage patterns: Hair drug testing can reveal drug use trends over time, rather than just recent consumption.

Limitations:

• Delayed detection of use: Drugs only become visible in hair approximately 5-7 days post-use.
• Expense: Hair drug tests tend to cost more compared to other testing methods.
• Variable results: Differences such as individual hair color and growth can impact drug metabolite concentrations in hair.

Note: These tests, though often labeled as "hair follicle tests," assess the hair strand itself, not the follicle lying 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. 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.
