Hair Follicle Drug Testing - Acme, LA

What it is, How it works

Hair screening has become recognized as a formidable method for identifying drug and alcohol consumption. Hair traps biomarkers within its growing strands, offering a prolonged history of alcohol and drug use. Collected near the scalp, hair can reveal a detection window of up to 3 months for alcohol and other substances. Collection is straightforward, it's relatively tamper-resistant, and simple to transport.

A 1.5-inch segment of around 200 hair strands (approximately matching a #2 pencil in size) closest to the scalp yields 100mg of hair, the optimal amount for screening and confirmation. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale to weigh the hair. In the absence of scalp hair, an equivalent amount of body hair may be used. When we refer to head hair, it specifically denotes scalp hair, while body hair encompasses all other hair forms (such as facial or axillary).

Process Overview

The laboratory procedure for processing drug test results comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning governs the initial sample integration into a laboratory's system, which involves confirming that the sample is sealed and shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and finalizing any pending data entry not covered by an electronic chain of custody framework.

Screening provides an initial rapid assessment for drug abuse. Despite being an economical approach to dismiss drug use in most samples, a positive screen demands confirmation for legal admissibility. Any samples with a presumptive positive in Screening necessitate a further confirmation.

Should a sample be presumptively positive during Screening, more hair is sourced from the primary specimen for Extraction. Here, drugs are extracted at considerably lower concentrations than other methods (such as urine or oral fluid), underscoring why hair drug screening is the most challenging method to conduct.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if required. The complete laboratory process from Accessioning to Confirmation undergoes assessment under the CAP (College of American Pathologists) Hair qualification and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests trace drug use up to 90 days, contrasting with the shorter window of urine tests.
• Hard to manipulate: Cheating a hair drug test is difficult, thus ensuring more reliable results.
• Visual historical usage: Offers an overview of drug patterns over time, not just recent use.

Limitations:

• Inability to unveil recent use: Drugs become noticeable in hair approximately after 5-7 days.
• Higher cost: Hair drug tests typically cost more compared to other testing techniques.
• Result discrepancies: Differences such as hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Often dubbed "hair follicle tests", the analysis actually examines the hair strand, not the 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.
