Hair Follicle Drug Testing - Rosemont, MD

What it is, How it works

Hair analysis has become recognized as an effective method for spotting drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drugs by embedding biomarkers in the fibers of the hair as it grows. When sampled near the scalp, hair can reveal drug and alcohol usage within a span of around three months. The collection process is easy, altering it is relatively challenging, and it’s straightforward to transport.

A segment measuring 1.5 inches, comprising roughly 200 hair strands (the thickness of a #2 pencil) next to the scalp will yield 100mg of hair, an optimal amount for both screening and validation. For EtG, additional tests, or more than 10 panels, a specimen amount of 150mg is optimal. Utilize a jeweler’s scale for weighing the specimen. Should scalp hair be absent, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory process concerning a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial introduction of a sample into a lab’s database. It includes confirming the sample’s proper sealing and transportation, allocating a random LAN (Laboratory Accessioning Number), and executing any additional data input not captured by an electronic chain of custody system.

Screening entails a preliminary rapid inspection for drugs of abuse. Though Screening serves as a cost-efficient measure to affirm no drug use for many samples, a positive screen necessitates further confirmation to stand in court. Samples flagged as potentially positive during Screening demand further validation.

Upon a presumptive positive in the Screening phase, additional specimen hair is extracted and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), marking hair drug screening as a highly complex method to execute.

Confirming any positive Screening outcome involves employing GC/MS, GC/MS/MS, or LC/MS/MS. Samples assessed as presumptively positive undergo washing before confirmation when necessary. The whole laboratory process, from Accessioning to Confirmation, undergoes review aligned with both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests detect drug use for up to 90 days, contrasting with urine tests possessing narrower detection windows.
• Hard to deceive: Hair drug testing is arduous to falsify, thereby delivering more reliable results.
• Holds past usage data: It reveals a trend of drug use over time, rather than merely recent consumption.

Limitations:

• Incapable of detecting recent use: It requires around 5-7 days for drugs to become discernible in hair.
• Expense: Hair drug testing tends to incur higher costs compared to other testing methods.
• Result variations: Variables such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Even though often denoted as "hair follicle tests," the examination evaluates the hair strand, not 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.
