Hair Follicle Drug Testing - Loyola, CA

What it is, How it works

Hair analyses have emerged as an influential method for identifying drug and alcohol consumption. The hair encases a prolonged history of alcohol and drug usage by capturing biomarkers within the growing hair strand's fibers. Collected near the scalp, hair can reveal a detection period of up to about three months for drugs and alcohol. Hair sampling is straightforward, relatively resistant to tampering, and convenient to transport.

A sample length of 1.5 inches comprising around 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, optimal for screening and confirmation. For EtG, additional tests, or multiple-panel tests, 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be obtained. 'Head hair' refers specifically to scalp hair, while 'body hair' encompasses all other hair types (such as facial and underarm hair).

Process Overview

The laboratory processing of drug test results incorporates four crucial procedures: Accessioning, Screening, Extraction, and Confirmation.

Accessioning implies the initial integration of a sample into a laboratory's system. This procedure includes confirming that the sample was properly sealed and shipped, allocating a random Laboratory Accessioning Number (LAN), and executing any additional data entries not supplied by an electronic chain of custody system.

Screening serves as an initial brisk assessment for substance abuse. Though Screening is economical for excluding drug use in most samples, positive outcomes necessitate confirmation to be acceptable in legal settings. Samples that are presumptively positive in Screening mandate subsequent confirmation.

If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. In this process, drugs are isolated from hair at notably lower concentrations compared to other techniques (such as urine or oral fluid), rendering hair drug screening as a challenging method to execute.

Confirmation of any positive screening findings employs GC/MS, GC/MS/MS, or LC/MS/MS. Any samples identified as presumptive positives undergo washing before confirmation if necessary. The end-to-end laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the standards set by ISO / IEC 17025.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug intake up to 90 days, in contrast to urine tests which offer a shorter detection timeframe.
• Challenging to tamper with: It is exceedingly challenging to tamper with a hair drug test, thereby enhancing result accuracy.
• Presents historical insight: It can display an overview of drug usage over time, unlike tests showing only recent usage.

Limitations:

• Incapability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing generally incurs higher costs compared to alternative testing methods.
• Result variability: Elements such as hair color and personal hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although commonly termed "hair follicle tests," the test evaluates the hair strand rather than 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.
