Hair Follicle Drug Testing - Arbutus, MD

What it is, How it works

Utilizing hair analysis has emerged as an effective method for identifying substance and alcohol consumption. Hair records a prolonged history of alcohol and drugs by embedding biomarkers within the hair fiber as it grows. When hair is gathered near the scalp, it can provide an approximate 3-month detection timeframe for substances and alcohol. Collection of hair is straightforward, moderately challenging to tamper, and simple to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for analysis and verification. For EtG, additional parameters, and/or tests exceeding 10 panels, a sample size of 150mg is suggested. It's advisable to use a jeweler’s scale for accurate weighing. If scalp hair isn't available, an equal quantity of body hair can be substituted. The term head hair specifically pertains to scalp hair. Body hair encompasses all other hair types (facial hair, axillary hair, etc.).

Process Summary

The processing of a drug test result in a lab involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary handling of a sample within the laboratory setup. This involves confirming the sample's proper sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and fulfilling any supplementary data entry absent in an electronic chain of custody system.

Screening carries out an initial swift assessment for drugs of misuse. It provides a cost-efficient means to disprove substance misuse across most samples; however, a positive screening result necessitates confirmation to be considered valid legally. Any samples that demonstrate a presumptive positive during Screening require a confirmatory follow-up.

When a sample yields a presumptive positive during Screening, more hair is extracted from the original sample and prepped for Extraction. In this phase, drug substances are isolated from hair at a notably lower concentration than with alternate techniques (e.g., urine or saliva), making hair drug testing the most complex methodology.

A confirmation for a positive screening outcome is completed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation if needed. The complete laboratory evaluation from Accessioning to Confirmation complies with the CAP (College of American Pathologists) Hair categorization and adheres to the ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection period: Hair drug tests can identify substance use for periods as long as 90 days, which contrasts with urine tests that have a shorter detection span.
• Difficult to falsify: Cheating with hair drug tests is extremely difficult, offering more reliable outcomes.
• Historical usage insight: Hair analysis offers a chronicle of drug use over an extended period instead of merely recent activity.

Constraints:

• Unable to detect recent usage: Substances typically become detectable in hair after about 5-7 days.
• Expense: Hair drug analysis usually incurs higher costs compared to other testing forms.
• Result variability: Factors including hair color and individual hair growth variations can influence drug metabolite concentration levels in the hair.

Note: Although commonly labeled as "hair follicle tests", the test actually examines the hair strand rather than the follicle underneath 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.
