Hair Follicle Drug Testing - Cabin John, MD

What it is, How it works

Hair assessments are now considered an effective means for identifying drug and alcohol consumption. Hair captures a lasting timeline of substances by embedding biomarkers within the strands of the hair as it grows. When procured near the root, hair offers roughly a 3-month period for detecting alcohol and drugs. Hair is straightforward to gather, fairly resistant to tampering, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (around the thickness of a #2 pencil) nearest the root yields 100mg, the ideal quantity for analysis and confirmation. For EtG, add-ons, and/or assessments beyond 10 panels, a 150mg sample is suggested. We advise weighing the sample using a jeweler’s scale. If head hair can't be collected, the same quantity of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug analysis consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary handling of a sample into a lab’s system. It involves verifying that the sample is securely sealed and dispatched correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any more data input not captured by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of concern. While it is a cost-efficient method to exclude drug use for the majority of samples, any positive indication must be validated for legal acceptability. Samples that are tentatively positive in Screening need a follow-up confirmation.

Should a sample be provisionally positive in the Screening phase, more hair is taken from the initial collection for Extraction. During this phase, drugs are separated from hair at significantly lower concentration levels than other methods (such as urine or oral fluid), explaining why hair drug screening is the most challenging method to execute.

Confirming any positive screening outcome employs techniques like GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as necessary. The entire sequence from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and follows the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for a duration of up to 90 days, unlike urine tests that have a shorter detection timeframe.
• Resistance to manipulation: Hair drug testing is hard to falsify, enhancing the integrity of the results.
• Offers historical insights: It reveals a record of drug use over a span of time, beyond just immediate usage.

Limitations:

• Inability to detect recent consumption: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests typically cost more than other drug testing approaches.
• Result variability: Elements like hair color and personal hair growth differences can influence the level of drug metabolites in hair.

Note: Although frequently termed as "hair follicle tests", the analysis focuses on the hair strand, 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.
