Hair Follicle Drug Testing - Mays Chapel, MD

What it is, How it works

Hair analysis has emerged as a highly effective method for identifying drug and alcohol consumption. Hair strands serve as a long-term record of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. When taken close to the scalp, hair can offer up to a 3-month detection period for alcohol and drugs. This method is straightforward to collect, relatively resistant to adulteration, and easy to mail.

A sample measuring 1.5 inches and containing approximately 200 hair strands (equivalent to the diameter of a #2 pencil) near the scalp yields 100mg of hair, meeting the ideal sample size for initial and confirmatory testing. For EtG, supplemental tests, and/or analyses exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair is not available, an equivalent volume of body hair can be utilized. References to head hair are specific to scalp hair, while body hair includes all other variants (facial, axillary, etc.).

Process Overview

The key stages in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary processing of a sample into the laboratory's system. This phase verifies the sample's proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and accommodates any extra data entry not covered by an electronic chain of custody system.

Screening conducts an initial expedient examination for drugs of abuse. Though Screening is economical for excluding drug usage in most samples, a positive outcome requires confirmation to be court-admissible. Samples presumptively positive in Screening necessitate additional confirmation.

For samples deemed presumptively positive in Screening, an extra quantity of hair is taken from the original specimen and prepped for Extraction. Here, drugs are extracted from hair at concentrations much lower than those found in other methodologies (e.g., urine or oral fluid), which renders hair drug screening the most challenging methodology to execute.

Confirmation of any positive result in Screening is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as applicable. From Accessioning to Confirmation, the complete laboratory procedure is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, surpassing urine tests which have a shorter detection span.
• Cheating is difficult: Hair drug tests present significant challenges to manipulation, enhancing result accuracy.
• Shows historical usage: It can outline a pattern of drug use over an extended timeframe, not confined to recent use.

Limitations:

• Inability to detect recent use: Detection of drugs in hair necessitates approximately 5-7 days.
• Higher cost: Hair drug tests generally incur more expense than alternative drug testing methods.
• Result variation: Elements like hair color and individual hair growth discrepancies can influence drug metabolite concentrations in hair.

Note: Despite being called "hair follicle tests", the analysis focuses on the hair strand itself instead of 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.
