Hair Follicle Drug Testing - County Center, VA

What it is, How it works

Hair testing has evolved into an effective means for identifying drug and alcohol consumption. The strands of growing hair capture biomarkers, providing a long-term record of alcohol and other drug use. When hair is gathered near the scalp, it can offer an approximately 3-month detection period for substances. Collecting hair is straightforward, somewhat resistant to tampering, and easily transportable.

A 1.5-inch hair sample, consisting of around 200 strands (roughly the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair — the optimal sample amount for testing and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is recommended to weigh the sample with a jeweler's scale. If scalp hair is not available, an equivalent quantity of body hair may be used. "Head hair" specifically means scalp hair, while "body hair" covers all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the preliminary processing of a sample into a lab's system. This process checks that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and handles any additional data entry not covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for drugs of abuse. While cost-effective for eliminating drug usage in most samples, a positive screen must be confirmed to be valid for court purposes. Samples that test presumptively positive at this stage require further confirmation.

If a sample shows a presumptive positive during Screening, additional hair from the initial sample is prepared for Extraction. Here, drugs are drawn from hair at a much lower concentration than in other methods (such as urine or oral fluid), which is why hair drug screening is notably challenging.

Confirmation of any positive screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive undergo a wash before confirmation if necessary. The complete lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, surpassing the shorter detection timeframe of urine tests.
• Challenge to falsify: The difficulty in deceiving a hair drug test enhances the accuracy of the results.
• Provides usage patterns: It reveals a timeline of drug use over an extended period, rather than only recent activity.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug tests are typically costlier than alternative drug testing methods.
• Result variations: Aspects like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although sometimes called "hair follicle tests," the analysis is performed on the hair strand itself, 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.
