Hair Follicle Drug Testing - Eighty Four, PA

What it is, How it works

Hair assessments have emerged as an influential method for uncovering drug and alcohol consumption. Hair provides a prolonged timeline of substance intake by embedding biomarkers within the growing hair's fibers. When gathered near the scalp, hair can reveal approximately a 3-month detection span for substances like alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and convenient to send.

A 1.5-inch segment consisting of roughly 200 strands of hair (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect sample size for both screening and confirmation purposes. For EtG, additional tests, and/or examinations surpassing 10 panels, 150mg of the sample is advised. It's suggested to measure the sample on a jeweler's scale. If head hair is not available, a comparable amount of body hair can be utilized. When discussing head hair, we solely refer to scalp hair. Body hair pertains to all other varieties (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab's infrastructure. This includes confirming the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplemental data entry absent in an electronic chain of custody setup.

Screening consists of a preliminary review for illegal drug presence. Though Screening is an economical approach to dismiss drug usage in many samples, a positive screen necessitates verification for legal proceedings. All samples deemed preliminarily positive in Screening require successive confirmation.

If a sample appears to be positive during the Screening phase, additional hair is obtained from the primary sample and prepared for Extraction. Here, substances are withdrawn from hair at a lesser concentration compared to methods like urine or oral fluid, rendering hair drug screening the most intricate method to conduct.

Verification of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as preliminarily positive are cleansed ahead of confirmation if necessary. The full laboratory procedure, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standards accreditation.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for up to 90 days, in contrast to the narrower detection window of urine tests.
• Challenging to falsify: The integrity of a hair drug test is tough to compromise, ensuring more reliable outcomes.
• Offers historical insights: It can illustrate a pattern of drug consumption over time, rather than just recent instances.

Constraints:

• Incapable of recent detection: Substances become detectable in hair after approximately 5-7 days.
• Expense: Typically, hair drug tests cost more compared to other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can alter the concentration of drug metabolites present in hair.

Note: Although often termed "hair follicle tests," the analysis is conducted on the hair strand itself, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
