Hair Follicle Drug Testing - Gettysburg, OH

What it is, How it works

Hair analysis is increasingly recognized as a crucial method for identifying drug and alcohol use. Hair captures a comprehensive timeline of alcohol and drug consumption by embedding biomarkers within the strands as they grow. When samples are taken near the scalp, they can represent roughly a 3-month time frame for detecting drugs and alcohol. Collecting hair is straightforward, relatively tamper-resistant, and easily transported.

A 1.5-inch section comprising around 200 hair strands (approximately the width of a #2 pencil) from the nearest point to the scalp yields 100mg of hair, which is ideal for both preliminary testing and confirmation. For EtG, additional testing, and/or evaluations exceeding 10 panels, a sample weighing 150mg is advisable. It is recommended to measure the hair sample using a jeweler’s scale. If there is no scalp hair available, a similar quantity of body hair can be used. References to head hair specifically indicate scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory examination of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial step of processing the sample into the laboratory’s system, which involves ensuring proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any additional information entry not already captured by an electronic chain of custody system.

Screening is an initial expedited examination for substances of abuse. Although Screening offers a cost-efficient approach to negate drug presence in most samples, a positive indication must be validated to be upheld in legal contexts. Samples that show presumptive positivity in Screening necessitate further verification.

When samples exhibit presumptive positivity in Screening, additional hair is prepared from the initial sample for Extraction. During this phase, substances are retrieved from hair at a much reduced concentration compared to other methods (e.g., urine or saliva), making hair drug screening the most challenging methodology.

Validation of positive Screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample is washed as required before confirmation. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair guidelines and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage over a potential 90-day span, surpassing urine tests that have a shorter detection range.
• Difficult to manipulate: Manipulating results of a hair drug test is challenging, enhancing accuracy.
• Offers chronological data: It can display a history of drug use over a duration, not solely recent activities.

Limitations:

• Unable to detect recent usage: Detecting drugs in hair requires roughly 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Factors like hair color and differences in individual hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the analysis is conducted on the hair strand rather than 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.
