Hair Follicle Drug Testing - Golden Meadow, LA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The hair captures biomarkers within the strands that grow, allowing for a historical view of substance intake. When hair is trimmed close to the scalp, it can provide approximately a 3-month timeframe for detecting alcohol and other drugs. Hair collection is easy, tamper-resistant, and convenient for shipping.

A sample of 1.5 inches comprising roughly 200 hair strands (comparable to a #2 pencil’s thickness) positioned nearest to the scalp yields 100mg of hair, optimal for both screening and verification. For EtG, supplements, and/or tests exceeding 10 panels, collecting 150mg is advised. Measuring the sample using a jeweler’s scale is recommended. In the absence of scalp hair, a matching amount of body hair can be obtained. The term head hair pertains solely to scalp hair, while body hair includes all other forms of hair (facial, axillary, etc.).

Process Overview

The essential steps in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial integration of a specimen into a laboratory’s framework. This step encompasses ensuring the sample is properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and performing outstanding data input not covered by an electronic chain of custody system.

Screening represents an initial rapid assessment for drug misuse. Although Screening offers a cost-efficient solution to eliminate drug use in most samples, a positive finding from this process requires confirmation to be legally valid. Any samples that test presumptively positive in Screening necessitate secondary confirmation.

Should a sample yield a presumptive positive at the Screening phase, additional hair is extracted from the primary sample and prepped for Extraction. During Extraction, drugs are removed from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), rendering it the most complex methodology for drug testing.

Positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive specimens are cleansed if indicated. The complete lab process, from Accessioning to Confirmation, is audited in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug consumption up to 90 days prior, unlike urine tests which have a narrower detection range.
• Hard to deceive: Hair drug evaluations are considerably challenging to manipulate, enhancing result reliability.
• Offers a historical consumption pattern: It can reveal drug use trends over some time, beyond just recent usage.

Limitations:

• Incapable of indicating recent consumption: Drugs typically require about 5-7 days to become traceable in hair.
• Expense: Hair drug evaluations tend to be pricier than alternative drug testing approaches.
• Result variability: Elements such as hair color and individual hair growth differences might impact drug metabolite levels in the hair.

Note: Commonly known as "hair follicle tests," this assessment actually examines the hair strand and 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.
