Hair Follicle Drug Testing - Black Springs, AR

What it is, How it works

Hair testing has emerged as a robust method for identifying alcohol and drug consumption. Hair captures a chronological record of alcohol and drug presence by embedding biomarkers within the structure of the hair as it develops. When sampled close to the scalp, hair offers an approximate 3-month period for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient for transport.

A 1.5-inch section comprising about 200 hair strands (comparable to the thickness of a #2 pencil) adjacent to the scalp yields 100mg of hair, which is the preferred quantity for analysis and verification. For EtG, additional panels, and/or tests exceeding 10 panels, a specimen of 150mg is advised. The specimen should be weighed using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair can be used. References to head hair specifically denote scalp hair, while body hair includes other hair types (facial, axillary, etc.).

Process Overview

The lab processing of drug tests comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into a lab’s database. This step involves ensuring the sample is securely sealed and properly shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any extra data not provided by an electronic chain of custody system.

Screening consists of a preliminary rapid assessment for drug abuse. Even though Screening serves as a cost-efficient means to exclude drug usage for the bulk of samples, a positive result requires confirmation to hold up in court. Samples that are tentatively positive in Screening necessitate further confirmation.

If a sample indicates a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or saliva), rendering hair drug screening a more complex procedure.

Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleansed before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use up to 90 days, whereas urine tests have a more limited detection window.
• Hard to falsify: Hair drug tests are notably difficult to manipulate, resulting in more reliable outcomes.
• Reveals long-term usage: It can illustrate a timeline of drug use over an extended duration, instead of merely recent use.

Limitations:

• Incapable of detecting recent consumption: It generally requires 5-7 days for drugs to become apparent in hair.
• Expense: Hair drug tests tend to be costlier than alternative drug testing methods.
• Result variability: Elements such as hair coloration and individual differences in hair growth can influence metabolite levels in the hair.

Note: Although frequently labeled as "hair follicle tests", the analysis focuses 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.
