Hair Follicle Drug Testing - Randallstown, MD

What it is, How it works

Hair analysis is increasingly viewed as an effective means for identifying the use of drugs and alcohol. Hair captures a long-term record of substance use by embedding biomarkers within its growing fibers. When clipped near the scalp, hair offers up to an approximately three-month timeframe for detecting alcohol and other substances. Hair is easy to collect, resistant to tampering, and straightforward to transport.

A 1.5-inch hair segment, containing about 200 strands (roughly the diameter of a #2 pencil) closest to the scalp, yields 100mg of hair, which is the optimal sample for screening and affirmation. For EtG, add-ons, and/or tests involving more than 10 panels, a specimen of 150mg is advisable. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not accessible, an equivalent amount of body hair may be gathered. References to head hair pertain to scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory workflow for processing a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the process by integrating a sample into a lab's system. This step involves confirming the proper sealing and shipment of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.

Screening constitutes a preliminary assessment for substance abuse. It provides a cost-effective method to exclude drug use in most samples, yet a positive screen must be validated to be considered admissible in legal proceedings. Samples showing presumptive positivity in Screening require additional confirmation.

When Screening suggests a positive result, more hair is retrieved from the original specimen for the Extraction phase. In this phase, drugs are retrieved from the hair in far smaller concentrations compared to other methods (like urine or oral fluid), making hair drug analysis the most challenging method to conduct.

Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleansed before confirmation as necessary. The comprehensive laboratory procedure from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for a duration of up to 90 days, whereas urine tests provide a shorter detection period.
• Resistance to tampering: It's extremely challenging to manipulate a hair drug test, thus yielding more reliable results.
• Produces historical data: It unveils a pattern of drug use over an extended span, beyond just recent consumption.

Limitations:

• Inability to identify recent consumption: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically pricier than alternative drug testing methods.
• Variability in outcomes: Factors like hair color and individual variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often termed "hair follicle tests", the procedure actually examines the hair strand rather than 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.
