Hair Follicle Drug Testing - Fishing Creek, MD

What it is, How it works

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair records a prolonged history of alcohol and other drug usage by capturing biomarkers within the fibers of the growing hair shaft. When collected close to the scalp, hair can offer up to roughly a 3-month detection period for alcohol and other drugs. Hair is straightforward to gather, somewhat resistant to tampering, and uncomplicated to transport.

A 1.5-inch sample of roughly 200 strands of hair (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimum sample for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is recommended. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be collected. In reference to head hair, we mean scalp hair only. Body hair includes all other hair types (such as facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial preparation of a sample in a laboratory’s system. This involves verifying that the sample was sealed and shipped accurately, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody system.

Screening provides a preliminary rapid evaluation for drugs of abuse. Though Screening is a cost-efficient method to rule out drug usage in a majority of samples, a positive screen must be confirmed to be valid in legal proceedings. Any samples deemed presumptively positive during Screening need a secondary confirmation.

If a sample is deemed presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at a notably lower concentration than with other methods (e.g., urine or oral fluid), which is why hair drug screening is considered the most challenging methodology to execute.

Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire laboratory process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have a shorter detection period.
• Increased difficulty to falsify: It is exceedingly difficult to evade a hair drug test, leading to more precise results.
• Delivers historical insight: It can reveal a pattern of drug use over time, rather than just recent usage.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Higher cost: Hair drug tests are typically more costly than other drug testing methods.
• Result variations: Factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite the term "hair follicle tests", the test analyzes 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. 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.
