Hair Follicle Drug Testing - Cowgill, MO

What it is, How it works

Hair analyses have emerged as an essential method for identifying drug and alcohol consumption. Hair serves as an extensive historical log for alcohol and drugs, securing biomarkers in the strands of the developing hair. When collected near the scalp, hair can offer a detection timeframe reaching up to roughly 3 months for alcohol and drugs. The procedure for collecting hair is straightforward, comparatively secure from tampering, and easily transported.

A 1.5-inch piece consisting of about 200 hair strands (roughly the dimension of a #2 pencil) nearest the scalp produces 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the hair is suggested. It is advisable to measure the hair on a jeweler’s scale. If hair from the scalp can't be collected, a similar amount of body hair might be taken. It's important to note that when mentioning head hair, it pertains to scalp hair exclusively. Body hair denotes any other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the preliminary stage where a sample is processed into a lab’s system. It comprises verifying the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not included by an electronic chain of custody system.

Screening performs an initial swift assessment for drugs of abuse. Although screening is an economical approach to negate drug use for the majority of samples, a positive result necessitates confirmation to be legally recognized. Any samples deemed potentially positive during screening are mandated to have further verification.

If a sample is indicated as potentially positive during screening, additional hair is extracted from the main sample and readied for Extraction. Here, drugs are withdrawn from hair at a considerably reduced concentration in comparison to alternative methods (e.g., urine or oral fluid), highlighting why hair drug examination is the most intricate approach to execute.

The confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All samples showing potential positivity are cleansed as required before confirmation. The complete laboratory procedure from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug consumption for up to 90 days, in contrast to urine assessments which possess a briefer detection period.
• Hard to deceive: Manipulating a hair drug assessment is highly challenging, resulting in higher accuracy.
• Offers historical insight: It reveals ongoing drug usage patterns, not just recent activity.

Limitations:

• Inability to detect recent consumption: It generally requires around 5-7 days for drugs to become traceable in hair.
• Cost: Hair drug assessments tend to be pricier than alternative drug testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: Although commonly termed "hair follicle tests", the examination targets the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Cowgill, MO, hair follicle testing surpasses traditional screening methods in several aspects. Accuracy and reliability are key benefits, as hair tests can detect a wide range of substances.

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.
