Hair Follicle Drug Testing - Humphreys, OK

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair can provide an extended timeline of alcohol and drug intake by encapsulating biomarkers within the strands as they grow. When trimmed near the scalp, hair can reveal information about substance use for up to three months. It’s straightforward to collect, tough to tamper with, and convenient to mail.

A section measuring 1.5 inches of roughly 200 hair strands (approximately analogous to a #2 pencil's diameter) nearest the scalp yields 100mg, which is perfect for testing and confirmation. For EtG, supplementary, or tests beyond 10 panels, 150mg is advised. It's best to weigh the sample using a jeweler’s scale. If the scalp hair isn't available, an equal body hair amount can be used. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (facial, underarm, etc.).

Process Overview

The primary stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial sample entry into the lab's system. This includes affirming proper sealing and shipping of the sample, assigning it an arbitrary LAN (Laboratory Accessioning Number), and covering any extra data input missing from an electronic chain of custody.

Screening conducts a preliminary brief analysis for substance abuse. While it economically dismisses drug usage in most samples, a positive screen must be validated to stand in legal scenarios. Any samples showing presumptive positivity during Screening require a follow-up confirmation.

For a sample with a presumptive positive result in Screening, additional hair is extracted from the initial batch and readied for Extraction. Here, drugs are drawn from hair at significantly lower concentrations compared to other techniques (for instance, urine or oral fluid), underscoring hair drug testing's complexity.

GC/MS, GC/MS/MS, or LC/MS/MS techniques handle the Confirmation of positive screening outcomes. Samples preliminary identified as positive are cleansed before confirmation if needed. The complete lab process from Accessioning to Confirmation undergoes scrutiny according to the CAP (College of American Pathologists) Hair standard and accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair tests can sense drug use for up to 90 days, unlike urine tests which have a narrower detection span.
• Hard to falsify: Cheating a hair test is tough, increasing result accuracy.
• Reveals use history: It displays a trend of substance use over time, not merely recent use.

Limitations:

• Recent use cannot be detected: Drugs become detectable in hair roughly 5-7 days post-use.
• Expense: Hair tests tend to be pricier than other drug testing options.
• Result inconsistencies: Variables like hair color and personal hair growth rates can influence the concentration of drug traces in hair.

Note: Although termed "hair follicle tests," the analyses focus on the hair strand, not the follicle below 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.
