Hair Follicle Drug Testing - Linton Hall, VA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers in the hair strands, hair reveals an extended timeline of substance usage. When hair samples are collected near the scalp, they can indicate alcohol and drug use for up to around three months. Hair is straightforward to gather, difficult to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp, will yield 100mg, which is optimal for screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, a 150mg specimen is preferred. It is suggested to weigh the sample on a jeweler’s scale. In the event that scalp hair cannot be collected, a similar quantity of body hair may be utilized. Mention of head hair exclusively refers to scalp hair, whereas body hair pertains to all other types (such as facial or axillary hair).

Process Overview

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

Accessioning is the first step where a sample is entered into the laboratory’s system. This step includes confirming that the sample was sealed and sent correctly, assigning it a random LAN (Laboratory Accessioning Number), and performing any additional data input not supplied by an electronic chain of custody system.

Screening is a preliminary assessment for substances of abuse. Although Screening is economical for excluding drug use in most samples, a positive result requires confirmation to be legally acceptable. Samples that show a potential positive in Screening necessitate further Confirmation.

Upon a presumptive positive in the Screening stage, more hair is extracted from the initial sample for the Extraction process. Here, drugs are isolated from hair in a more diluted form compared to other techniques (for example, urine or oral fluid), explaining why hair drug testing is the most challenging methodology to carry out.

Confirmation of any positive Screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as required before Confirmation. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for as long as 90 days, as opposed to urine tests which examine a shorter timeframe.
• Hard to falsify: It's extremely challenging to evade a hair drug test, which enhances the accuracy of findings.
• Offers historical insight: It can exhibit a use pattern over time, rather than just current consumption.

Limitations:

• Doesn't detect recent consumption: It requires about 5-7 days for drugs to become traceable in hair.
• Higher cost: Hair drug tests are typically pricier than other testing approaches.
• Result variability: Variances such as hair color and individual hair growth rates can influence the presence of drug metabolites in hair.

Note: Though commonly known as "hair follicle tests", this test analyzes 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.
