Hair Follicle Drug Testing - Fairview, MD

What it is, How it works

Hair analysis is now recognized as an effective instrument for identifying drug and alcohol usage. Hair can encapsulate a long-term record of alcohol and drug presence by embedding biomarkers within the strand's fibers as it grows. When hair is sourced near the scalp, it presents roughly a 3-month window of detection for alcohol and drugs. It's straightforward to gather, somewhat resistant to tampering, and convenient for transportation.

A sample measuring 1.5 inches and consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg, which is the optimal amount for both preliminary and confirmatory tests. For EtG, additional substances, or tests exceeding 10 panels, acquiring 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is unavailable, an equivalent quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" includes other types (e.g., facial, axillary).

Process Overview

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

Accessioning is the initial stage of incorporating a sample into a lab's system. This phase verifies proper sealing and shipping of the sample, assigns it a random LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic chain of custody system.

Screening offers an initial rapid evaluation for drugs of abuse. Although Screening is an economic approach to exclude drug use in most samples, a positive outcome must be verified for court acceptance. Any samples with presumptive positive results in Screening require a secondary confirmation.

Should a Screening suggest a presumptive positive, additional hair is extracted from the main sample and prepped for Extraction. At this juncture, hair undergoes extraction at concentrations significantly lower than those found in other methods (such as urine or oral fluid), contributing to hair drug screening's complexity.

Confirmation of any positive Screening results takes place via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed as necessary before Confirmation. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing exposes drug use over a 90-day duration, compared to the more limited timeframe of urine tests.
• Resistance to manipulation: The challenge of tampering with a hair drug test increases result reliability.
• Historical usage insight: It reflects a timeline of drug consumption patterns, not just recent usage.

Limitations:

• Inability to detect recent usage: Drugs generally become detectable in hair within 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Often termed as "hair follicle tests", the actual analysis targets 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. 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.
