Hair Follicle Drug Testing - Indian Lake, PA

What it is, How it works

Hair tests have gained popularity as an effective means of identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug use by embedding biomarkers within the strands of hair as it grows. When taken close to the scalp, hair can offer a detection span of up to three months for both alcohol and drugs. The process of obtaining hair is straightforward, relatively tamper-resistant, and convenient for transport.

A 1.5-inch section of about 200 hair strands, akin to the thickness of a #2 pencil, near the scalp yields around 100mg of hair, the optimal sample size for both screening and verification. For EtG, added tests, and tests exceeding 10 panels, 150mg is suggested. It is advisable to measure the specimen using a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be used. References to head hair pertain exclusively to scalp hair. Body hair denotes all other types (e.g., facial, axillary).

Process Overview

The lab handling of drug test outcomes involves Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a sample into the lab's workflow. This step ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not handled by electronic systems.

Screening provides a preliminary assessment for drugs of abuse. Though a cost-efficient approach to negate drug usage in most cases, a positive screening necessitates confirmation for legal admissibility. Samples that test positive in Screening require a subsequent confirmation.

A presumptive positive in Screening results in additional hair being extracted from the original sample for Extraction. In this stage, drug substances are isolated from hair at much finer concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples identified as presumptive positives undergo washing prior to confirmation. The end-to-end lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the adherence to 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 urine tests which have a shorter detection span.
• Resistance to tampering: It is notably challenging to manipulate a hair drug test, thereby enhancing result accuracy.
• Provides chronological data: It can illustrate a pattern of drug consumption over a duration, beyond recent usage.

Limitations:

• Lacks detection of recent use: Approximately 5-7 days are needed for drugs to become traceable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Variability in results: Elements such as hair color and personal hair growth rates may influence drug metabolite concentration in hair.

Note: Although frequently termed "hair follicle tests", the analysis focuses on the hair strand, excluding the hair 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.
