Hair Follicle Drug Testing - Antrim, LA

What it is, How it works

Hair testing is increasingly seen as an effective means for identifying drug and alcohol consumption. By encasing biomarkers within the strands' fibers, hair offers a long-term record of alcohol and drug intake. Proximity to the scalp allows hair to reveal a near 3-month detection range for alcohol and drugs. It’s easy to gather, challenging to tamper with, and straightforward to transport.

A sample length of 1.5 inches comprising roughly 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp yields 100mg, which is the optimal quantity for screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, 150mg is suggested. A jeweler's scale is recommended for weighing the specimen. In the absence of scalp hair, an equivalent from body hair may be used. The term head hair exclusively refers to scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result comprises four critical phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial integration into a lab’s system. This entails confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and inputting any ancillary data not covered by an electronic chain of custody.

Screening conducts a preliminary assessment for drugs of abuse. Although it is an economical method to exclude drug consumption in most samples, positive results in Screening require further verification for court validity. Presumptive positives in Screening necessitate a secondary confirmation step.

For results presumed positive at Screening, additional hair from the original sample is extracted for further processing. Drugs are retrieved from hair at significantly lower concentrations compared to alternate methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique.

Verification of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Samples deemed presumptive positives are washed prior to any necessary confirmation. The complete process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection scope.
• Hard to falsify: It is exceedingly difficult to compromise a hair drug test, enhancing the accuracy of results.
• Offers chronological insights: It provides a depiction of drug use over time, not just recent intake.

Limitations:

• Inability to detect recent use: Detection of drugs in hair requires approximately 5-7 days.
• Expense: Hair drug evaluations are typically pricier than alternate testing methods.
• Result variability: Individual differences such as hair color and growth rates can influence drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests", the assessment examines the hair strand itself, not the underlying scalp follicle.

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.
