Hair Follicle Drug Testing - Forest Center, MN

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair offers an extended historical account of alcohol and drug use by embedding biomarkers within the hair strands as they grow. When sourced near the scalp, hair can present a detection timeline of nearly 3 months for alcohol and drugs. Collection of hair is straightforward, relatively resistant to tampering, and easily transportable.

Securing a 1.5-inch segment of roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp yields about 100mg of hair, the preferred sample size for analysis and verification. For EtG, supplemental analyses, and/or tests exceeding 10 panels, a 150mg sample is advised. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair is not feasible, a comparable quantity of body hair may be retrieved. When mentioning head hair, it pertains solely to scalp hair. Body hair refers to all other hair categories (facial, axillary, etc.).

Process Overview

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

Accessioning entails the preliminary integration of a sample into a lab’s system. This step includes verifying proper sealing and dispatch of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry absent from an electronic chain of custody system.

Screening comprises an initial swift evaluation for substances of misuse. While Screening is a cost-efficient technique to eliminate drug usage in most samples, a positive screen must be corroborated to stand legally. Samples with a presumptive positive in Screening require an additional verification.

For samples showing a presumptive positive in the Screening phase, more hair is drawn from the original sample for the Extraction process. At this stage, drugs are extracted from the hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to conduct.

Verification of any positive screening outcome is achieved through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing prior to validation if necessary. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests that offer a shorter detection span.
• Hard to circumvent: It is quite challenging to deceive a hair drug test, ensuring more precise results.
• Supplies chronological insight: It can showcase a pattern of drug usage over time, not just recent consumption.

Limitations:

• Inability to identify recent use: Drugs take nearly 5-7 days to be detectable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug testing approaches.
• Result variability: Factors like hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite often being termed as "hair follicle tests", the test examines the hair strand and 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.
