Hair Follicle Drug Testing - Darlington, MD

What it is, How it works

Hair analysis has become a recognized method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by encapsulating biomarkers within the strands. When collected near the scalp, hair can offer a detection window of up to three months for alcohol and various drugs. It's straightforward to collect hair, challenging to tamper with, and easy to transport.

A 1.5-inch hair sample consisting of roughly 200 strands (similar in diameter to a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample size for testing and validation. For EtG, additional substances, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest weighing the sample on a jeweler’s scale. If scalp hair isn't accessible, an equivalent amount of body hair can be sampled. When we mention head hair, it refers solely to scalp hair. Body hair includes all other hair types (such as facial, axillary, etc.).

Process Overview

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

Accessioning is the preliminary processing phase of integrating a sample into a lab's system. It entails verifying that the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not already in an electronic chain of custody system.

Screening involves an initial assessment for controlled substance usage. Although Screening is a cost-efficient means to rule out drug use in the majority of samples, a positive screen must be verified to be admissible in legal contexts. Samples that are initially flagged as positive in Screening require further confirmation.

If a sample is flagged positive during Screening, additional hair is removed from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at lower concentrations than alternative methods (such as urine or saliva), making hair drug screening one of the most complex techniques.

Confirmation of any positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed as required before confirmation. The entire lab process, from Accessioning to Confirmation, is carefully evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can discover drug use for up to 90 days, in contrast to urine tests which offer a shorter detection window.
• Challenging to falsify: Cheating a hair drug test is exceptionally hard, ensuring more reliable results.
• Historic usage info: It reveals a timeline of drug consumption over extended durations, not just recent usage.

Limitations:

• Lacks detection of recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variations: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Though often described as "hair follicle tests", the test itself 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.
