Hair Follicle Drug Testing - Desha, AR

What it is, How it works

The use of hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair strands capture a long-term record of drugs and alcohol by embedding biomarkers within the fibers as they form. When hair is taken from near the scalp, it can reveal drug and alcohol use for a period of up to three months. The collection of hair samples is straightforward, hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches of about 200 hair strands (roughly matching the circumference of a #2 pencil) cut nearest to the scalp can yield 100mg of hair, which is the optimal quantity for testing and subsequent confirmation. For EtG, additional panels, or tests beyond 10 panels, a recommended 150mg sample should be weighed using a jeweler’s scale. If scalp hair cannot be collected, an equivalent mass of body hair is acceptable. Head hair explicitly refers to scalp hair, whereas body hair encompasses all other types (such as facial or axillary).

Process Overview

The laboratory procedures to process a drug test include four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the entry phase of getting a sample into a lab's workflow. This stage involves making sure the sample has been securely sealed and correctly transported, generating a random LAN (Laboratory Accessioning Number), and completing necessary data entry that is not covered by an electronic chain of custody system.

Screening is the first examination for substances of misuse. Although Screening offers an economical way to check a large number of samples, a positive reading must be confirmed to be legitimately acceptable in legal situations. Samples that yield a presumptive positive during Screening need to undergo another confirmation test.

Should any sample show a presumptive positive at the Screening phase, additional hair from the original sample is taken for use in Extraction. This phase removes drugs from hair at remarkably lower levels than in other testing methods like urine or oral fluids, illustrating why hair drug testing is the most complex method to perform.

Confirmation for any positive results from Screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before Confirmation, all presumptive positive samples undergo washing as necessary. Every step in the laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standard and the accreditation of ISO / IEC 17025 protocols.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use span up to 90 days, unlike urine tests which cover shorter periods.
• High accuracy preventing deception: Results are more reliable due to difficulty in circumventing a hair drug test.
• Chronological data: Capable of illustrating a timeline of drug use over an extended duration, beyond just recent consumption.

Limitations:

• Incapable of revealing immediate use: A period of approximately 5-7 days is required before substances appear in hair samples.
• Higher costs: Generally, hair drug testing is more costly than other methods of drug screening.
• Result fluctuations: Factors such as hair pigmentation and personal hair growth rates can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," this test focuses on analyzing 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
