Hair Follicle Drug Testing - Ashley, MO

What it is, How it works

Hair analysis has emerged as an influential resource for identifying substance and alcohol consumption. Hair offers an extended timeline of alcohol and drug presence by capturing biomarkers within the strands of developing hair. When obtained near the scalp, hair can exhibit an approximate 3-month detection period for alcohol and other substances. Hair is straightforward to gather, reasonably challenging to tamper with, and convenient to transport.

A segment measuring 1.5 inches comprising around 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, supplementary tests, and/or examinations exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be obtained. When mentioning head hair, we exclusively refer to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The four primary steps in the lab analysis of a substance test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into a laboratory’s system. This includes verifying that the sample was sealed and shipped properly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not provided by an electronic chain of custody system.

Screening involves an initial quick check for drugs of abuse. While Screening is a cost-effective way to rule out drug usage on the majority of samples, a positive screen needs to be confirmed to be admissible in court. Any samples that are presumptively positive in Screening do require a secondary confirmation.

If a sample is presumptively positive in the Screening stage, more hair is pulled from the initial specimen and prepared for Extraction. In this stage, drugs are extracted from hair at a much lower concentration than in other methodologies (ex. urine or oral fluid), which is why hair drug screening is the most difficult methodology to perform.

Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as needed. The entire laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug assessments can recognize substance use for up to 90 days, whereas urine tests have a more brief detection period.
• Challenging to deceive: It is notably challenging to deceive a hair drug assessment, enhancing the accuracy of the outcomes.
• Offers historical context: It can delineate a pattern of drug consumption over time, rather than just recent usage.

Limitations:

• Inability to detect recent consumption: It takes roughly 5-7 days for substances to become identifiable in hair.
• Expense: Hair drug assessments typically cost more than other testing methods.
• Result variations: Elements such as hair color and individual growth variability can impact the concentration of drug metabolites in the hair.

Note: Although commonly known as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
