Hair Follicle Drug Testing - Effie, LA

What it is, How it works

The utilization of hair testing has emerged as an effective means for uncovering drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by confining biomarkers within the strands of hair as it grows. When hair is gathered near the scalp, it can offer up to about a 3-month timeframe for detecting alcohol and various drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.

An optimal 1.5-inch hair sample from around 200 strands (roughly the size of a #2 pencil) nearest to the scalp will yield 100mg, suitable for screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the specimen with a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be taken. By head hair, we imply only scalp hair. Body hair includes other types like facial or axillary hair.

Process Overview

The core stages of processing a drug test in the laboratory encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial registration of a sample within the lab's system. This step ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any requisite data input absent from an electronic chain of custody system.

Screening involves a preliminary rapid assessment for substance misuse. Although Screening is an economical means to eliminate drug use in most samples, a positive outcome demands confirmation for legal admissibility. Any samples that test presumptively positive at Screening require subsequent confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drug extraction from hair occurs at a notably lower concentration than in alternative methodologies (e.g., urine or oral fluid), rendering hair drug testing particularly challenging to conduct.

Verification of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo cleansing before confirmation as necessary. The complete laboratory sequence from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug analyses can identify drug use for a span of up to 90 days, in contrast to urine analyses which provide a shorter detection span.
• Resistance to cheating: Cheating a hair drug test is exceedingly challenging, thus enhancing result accuracy.
• Offers historical insight: It illustrates a usage pattern over time, not merely recent activity.

Limitations:

• Incapability to detect recent consumption: It generally takes 5-7 days for substances to manifest in hair.
• Expense: Hair drug tests are typically costlier than other testing techniques.
• Result variability: Variables such as hair color and personal growth rate can influence drug metabolite concentration within hair.

Note: Although commonly termed "hair follicle tests," the analysis pertains to 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. 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.
