Hair Follicle Drug Testing - Poolesville, MD

What it is, How it works

Hair testing has become recognized as an effective instrument for detecting drug and alcohol consumption. Hair captures biomarkers in the fibers of the hair strand, offering an extended history of substance usage. When collected near the scalp, it can reveal a detection period of up to about three months for alcohol and drugs. Hair samples are easy to gather, relatively tough to tamper with, and simple to transport.

A 1.5-inch piece comprising roughly 200 hair strands (akin to the size of a #2 pencil) nearest the scalp yields 100mg of hair, ideal for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. Employ a jeweler’s scale for weighing the specimen. If scalp hair is unavailable, an equivalent amount of body hair may be utilized. Reference to head hair implies scalp hair only, while body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The primary procedures in processing a lab drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the initial integration of a sample into a lab system. This involves ensuring the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finishing any additional data entry absent in an electronic chain of custody system.

Screening represents an initial rapid examination for drugs of abuse. Although Screening is cost-effective for ruling out drug use in most samples, a positive screen necessitates confirmation for court admissibility. Any samples presumptively positive in Screening mandate secondary confirmation.

Should a sample show presumed positivity in Screening, additional hair is extracted from the initial specimen and prepared for Extraction. During this phase, drugs are removed from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Confirmation of any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples are washed as required. The comprehensive lab process from Accessioning to Confirmation undergoes review 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 track drug use for up to 90 days, unlike urine tests with shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is exceedingly difficult, enhancing accuracy.
• Reveals historical usage: Demonstrates a usage pattern over time, not just recent intake.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug testing usually incurs higher costs than other testing methods.
• Result variations: Elements like hair color and personal differences in hair growth can impact drug metabolite concentration.

Note: Despite the common term "hair follicle tests", this analysis targets 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.
