Hair Follicle Drug Testing - Havre De Grace, MD

What it is, How it works

Hair testing is recognized as an effective technique for detecting drug and alcohol consumption. Hair captures a long-term history of alcohol and drugs by trapping biomarkers within the fibers of the growing hair strand. When gathered close to the scalp, hair can offer up to a 3-month detection period for alcohol and other substances. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the ideal sample for testing and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is recommended. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is unavailable, an equivalent amount of body hair could be gathered. When mentioning head hair, we mean scalp hair exclusively. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The process in a lab for analyzing a drug test result is composed of Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial intake of a sample into the lab’s system. This involves confirming that the sample was sealed correctly and shipped adequately, assigning a random LAN (Laboratory Accessioning Number), and adding any additional data entry absent in an electronic chain of custody system.

Screening is an initial rapid assessment for drugs of abuse. While Screening is a cost-effective method to exclude drug use in most samples, a positive screen requires confirmation to be admissible in legal settings. Any samples presumptively positive in Screening need a secondary verification.

If a sample is presumptively positive in Screening, additional hair is extracted from the initial specimen and prepped for Extraction. In this stage, drugs are extracted from hair at much lower concentrations compared to other methodologies (ex. urine or oral fluid), making hair drug screening the hardest methodology to perform.

Confirmation of any positive Screening result is done via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Difficult to manipulate: Cheating a hair drug test is quite hard, making outcomes more accurate.
• Supplies historical insights: It can show a pattern of drug consumption over time, not just recent usage.

Limitations:

• Cannot identify recent consumption: It takes roughly 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests generally cost more than other drug testing approaches.
• Result variations: Elements like hair color and individual variations in hair growth can alter the concentration of drug metabolites in the hair.

Note: While frequently referred to as "hair follicle tests," the test examines the hair strand rather than the hair 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.
