Hair Follicle Drug Testing - Agnos, AR

What it is, How it works

Hair testing is widely regarded as an effective method for detecting drug and alcohol consumption. By encasing biomarkers within the strands of hair, it offers a prolonged history of substance use. Hair collected near the scalp can provide a detection timeframe of up to three months for alcohol and drug presence. It's easy to gather, fairly tamper-resistant, and straightforward to transport.

A 1.5-inch sample encompassing roughly 200 hair strands (equivalent to a #2 pencil's thickness) nearest to the scalp yields 100mg, which is perfect for screening and verification. When conducting tests such as EtG, add-ons, or those exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale is recommended to measure the specimen weight. If scalp hair isn't accessible, the same quantity of body hair can be used. Here, head hair exclusively means scalp hair, while body hair denotes other types (such as facial or axillary).

Process Overview

The lab processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary task of incorporating a sample into a lab's system, ensuring the sample's secure sealing and transport, allotting a random LAN (Laboratory Accessioning Number), and completing any supplementary data input that an electronic chain of custody system hasn't provided.

Screening is a preliminary look for drugs of concern. Although a frugal method to exclude drug presence mostly, confirmatory steps must follow a positive screen to be court-relevant. Presumptive positive samples from Screening necessitate secondary authentication.

When a sample tests presumptive positive in Screening, further hair is extracted from the reserved sample and prepped for Extraction. This phase involves extracting drugs from hair at notably low concentrations compared to other methods (such as urine or oral fluid), attributing to the complexity of hair drug screening.

Positive screening confirmations occur via GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation washing of presumptively positive samples is done if needed. The entire lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can find drug use up to 90 days, unlike urine tests with shorter spans.
• Hard to fake: Manipulating results is challenging with hair drug tests, ensuring higher accuracy.
• Shows historical patterns: Identifies a trend of drug use over durations, not merely recent consumption.

Limitations:

• Incapable of recent detection: It generally requires 5-7 days for drugs to appear in hair.
• Expense: Hair drug testing typically costs more compared to other testing methods.
• Result variability: Elements like hair color and different growth rates might influence metabolite concentrations.

Note: Though commonly termed "hair follicle tests", the test assesses the hair strand instead of 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.
