Hair Follicle Drug Testing - Institute, WI

What it is, How it works

Hair examinations are now recognized as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug use by encapsulating biomarkers within its fibers as it grows. When obtained near the scalp, hair can reveal up to around a three-month detection timeframe for both alcohol and drugs. Hair is straightforward to gather, somewhat hard to tamper with, and straightforward to transport.

A 1.5-inch segment comprising roughly 200 hair strands (approximately #2 pencil thickness) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For additional EtG tests or when testing surpasses 10 panels, 150mg of the specimen is advised. It is suggested to weigh the specimen on a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair can be collected. When addressing head hair, this implies exclusively scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The four foundational stages in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initiation of a sample into a laboratory's framework. This includes ensuring the sample was suitably sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any further data input absent from an electronic chain of custody system.

Screening introduces a preliminary rapid assessment for substances of misuse. Although Screening is a cost-efficient approach to discount drug usage for most samples, a positive screen necessitates confirmation for courtroom suitability. Any samples deemed presumptively positive during Screening do require subsequent verification.

In cases where a sample is considered presumptively positive during the Screening phase, additional hair is drawn from the initial specimen and readied for Extraction. During this phase, drugs are extracted from hair at markedly lower concentrations than in different techniques (e.g., urine or oral fluid), affirming why hair drug screening is the most intricate technique to execute.

Verification of any positive screening result is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and in line with the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Protracted detection period: Hair drug analyses can identify drug use for up to 90 days, as opposed to urine tests which possess a shorter detection period.
• Challenging to deceive: Cheating a hair drug test is exceedingly tough, rendering the results more trustworthy.
• Offers historical data: It can deliver a chronological pattern of drug usage over a timeframe, not solely recent consumption.

Limitations:

• Cannot identify recent usage: It typically takes 5-7 days for drugs to manifest in hair.
• Expense: Hair drug analyses usually incur higher costs than other drug testing techniques.
• Result variations: Factors like hair color and personal differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: Despite often being called "hair follicle tests", the procedure actually examines 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.

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.
