Hair Follicle Drug Testing - Wagon Wheel, AZ

What it is, How it works

Hair testing is now recognized as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and other drug use by embedding biomarkers within the fibers of the hair strand as it grows. When obtained near the scalp, hair can reveal a detection period of up to three months for alcohol and various drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (equivalent to the thickness of a #2 pencil), taken closest to the scalp provides 100mg of hair, which is the preferred sample amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair only. Body hair encompasses all other types of hair (such as facial or axillary).

Process Overview

The primary phases in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial processing into a lab's system, which includes confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not automatically supplied by an electronic chain of custody system.

Screening serves as an initial rapid assessment for drugs of abuse. Screening is cost-efficient for excluding drug usage in most samples, yet a positive screening must be verified for judicial acceptance. Any samples that screen presumptively positive necessitate further confirmation.

If a sample registers presumptively positive during Screening, additional hair is extracted from the initial specimen and prepared for Extraction. This phase involves extracting drugs from hair at a significantly lower concentration than seen in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.

Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo necessary washing prior to confirmation. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for a period of up to 90 days, compared to urine tests with a shorter detection timeframe.
• Harder to falsify: Altering the outcome of a hair drug test is quite difficult, leading to more reliable results.
• Reveals historical patterns: Hair testing can exhibit a timeline of drug use over time, beyond just recent consumption.

Limitations:

• Incapable of detecting recent consumption: Detecting drugs in hair takes roughly 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs than alternative drug testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites.

Note: Despite being termed "hair follicle tests", the analysis involves the hair strand itself, 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.
