Hair Follicle Drug Testing - Lake Caroline, VA

What it is, How it works

Hair analysis is increasingly recognized as an effective means to identify drug and alcohol consumption. The hair strands can hold historical evidence of these substances, capturing biological markers in its growing strands. When taken from near the scalp, hair samples deliver an approximate three-month detection period for drugs and alcohol. The process of hair collection is straightforward, challenging to tamper with, and convenient for transportation.

A 1.5-inch strand bundle, containing approximately 200 hair strands (roughly the thickness of a #2 pencil) adjacent to the scalp, yields 100mg, which is deemed suitable for evaluation and validation. For EtG additions or tests exceeding 10 panels, 150mg of hair is advisable. It is recommended to measure the hair sample using a jeweler’s scale. Should scalp hair not be accessible, the equivalent quantity of body hair can be procured. By head hair, we mean scalp hair only. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The core laboratory steps for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary handling of a sample within a lab’s system. It entails confirming the sample’s secured shipment, assigning a random LAN (Laboratory Accessioning Number), and executing supplemental data entry absent from an electronic chain of custody.

Screening refers to a preliminary rapid assessment for drug traces. Although Screening efficiently excludes drug use in most samples, any positive screening needs verification for legal submission. Presumptive positive screenings require subsequent confirmation.

A sample deemed presumptively positive during Screening necessitates additional hair from the specimen for Extraction. During this stage, drugs are retrieved from the hair at concentrations much lower than other techniques (e.g., urine or oral fluid), establishing hair drug screening as the most challenging methodology.

The GC/MS, GC/MS/MS, or LC/MS/MS technology is employed to substantiate any positive Screening outcomes. Presumptive positive samples are cleansed before confirmation as necessary. The comprehensive lab sequence from Accessioning to Confirmation is evaluated by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection span: Hair tests reveal drug consumption over a 90-day stretch, whereas urine tests have a briefer detection window.
• Hard to falsify: Cheating a hair drug test is highly improbable, thus enhancing result accuracy.
• Chronological data: The test provides drug use trends over time rather than detecting only recent consumption.

Limitations:

• Recent use undetectable: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing typically incurs higher costs than other testing methods.
• Result variability: Elements like hair color and individual growth variances can influence drug metabolite levels in hair.

Note: Although frequently labeled as "hair follicle tests," the analysis targets 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. 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
