Hair Follicle Drug Testing - Carlyss, LA

What it is, How it works

Hair testing is now regarded as an effective means of identifying drug and alcohol consumption. Hair captures long-term records of drugs and alcohol by securing biomarkers within the fibers of the growing strand. When taken near the scalp, it offers up to a roughly 3-month detection window for drugs and alcohol. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.

A sampling size of 1.5 inches, approximately 200 hair strands (around the width of a #2 pencil), closest to the scalp provides 100mg, which is perfect for screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, a 150mg specimen is advised. Using a jeweler’s scale for measurement is suggested. Should scalp hair be unavailable, a proportional amount of body hair can be collected. References to head hair specify only scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning handles the initial processing of a sample in a laboratory system. This process involves confirming the sample's seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any left-out data entry absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. While Screening is a budget-friendly method to rule out drug use in most samples, a positive screen requires confirmation to be court-admissible. Any samples showing presumptive positivity in Screening demand further verification.

A sample showing presumptive positivity in Screening has additional hair taken from the original specimen for Extraction. At this stage, drugs are isolated at a significantly lower concentration than in other methods (like urine or oral fluid), which makes hair drug screening a challenging methodology to execute.

Confirmation of any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleaned before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 criteria.

Pros of hair drug testing:

• Extended detection window: Hair drug assessments can reveal drug use for up to 90 days, unlike urine tests with a shorter detection period.
• Hard to manipulate: Cheating on a hair drug test is quite difficult, leading to more precise results.
• Offers historical data: It offers a pattern of drug use over time, not just recent use.

Drawbacks:

• Lacks recent use detection: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug assessments are typically costlier than other testing approaches.
• Result variances: Variables like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although termed as "hair follicle tests", the analysis is performed on the hair strand, not the follicle under 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
