Hair Follicle Drug Testing - Kimbrough, AL

What it is, How it works

Hair screening has emerged as a potent instrument for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the strands of growing hair. When taken close to the scalp, hair can deliver nearly a 3-month detection period for alcohol and other substances. Hair is straightforward to gather, somewhat challenging to tamper with, and easy to dispatch.

A 1.5-inch hair sample comprising roughly 200 strands (comparable to a #2 pencil in size) nearest to the scalp will yield 100mg of hair, the optimal sample size for screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, it's advised to use 150mg of the sample. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is absent, a similar quantity of body hair can be collected. In the context of head hair, this pertains exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

During Accessioning, the initial processing of a sample into the laboratory system is conducted. This process includes confirming that the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not provided by an electronic chain of custody system.

Screening provides an initial rapid examination for drugs of abuse. Although Screening offers a cost-effective means to dismiss drug usage for the majority of samples, a positive result necessitates confirmation for court admissibility. Samples identified as presumptively positive in Screening demand a secondary confirmation.

Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methodologies (such as urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of a positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The entire lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests provide detection for up to 90 days, surpassing the shorter detection span of urine tests.
• Difficulty to cheat: Cheating a hair drug test is notably difficult, ensuring more precise results.
• Provides historical data: It delivers a record of drug use over time, rather than just recent use.

Limitations:

• Cannot detect recent use: It generally requires 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests tend to be pricier compared to alternative drug testing methods.
• Variations in results: Factors such as hair color and individual hair growth patterns can influence the concentration of drug metabolites in hair.

Note: Although often termed as "hair follicle tests", the procedure analyzes 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.
