Hair Follicle Drug Testing - Colo, IA

What it is, How it works

Hair assessments have gained prominence as an effective means for identifying drug and alcohol consumption. The fibers of a growing hair strand capture biomarkers, offering a prolonged historical record of alcohol and drug presence. Collecting hair near the scalp provides a window of detection for up to roughly three months concerning alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (resembling a #2 pencil) from the scalp delivers 100mg of hair, which is the ideal sample size for both screening and confirmation processes. For EtG, additional tests, and test panels exceeding 10, a 150mg specimen is suggested. It is recommended that the specimen be weighed with a jeweler's scale. Should scalp hair be inaccessible, an equivalent amount of body hair is a suitable substitute. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types, such as facial and axillary hair.

Process Overview

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

Accessioning is the preliminary step where a sample is entered into the laboratory's system. This step ensures the sample was sealed and dispatched correctly, assigns a LAN (Laboratory Accessioning Number), and includes any supplemental data entry not captured by an electronic chain of custody system.

Screening provides an initial rapid assessment for substances of abuse. While a cost-effective strategy to eliminate drug use in many samples, a positive screen necessitates confirmation for legal admissibility. Samples with presumptive positive screenings require further confirmation.

For samples with a presumptive positive result in Screening, additional hair is extracted from the original specimen for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive outcomes undergo washing prior to confirmation when needed. The comprehensive process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and certified to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can identify drug use for up to 90 days, unlike urine tests that have a shorter timespan.
• Challenging to deceive: Cheating a hair drug test is extremely difficult, thus improving result accuracy.
• Historical usage data: Hair tests offer patterns of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing is often costlier than alternative drug testing methods.
• Result variability: Factors such as hair color and personal hair growth differences can influence drug metabolite concentrations within the hair.

Note: Despite being known as "hair follicle tests," the analysis is conducted on the hair strand itself, not on 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.
