Hair Follicle Drug Testing - Gray, IA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol use. Hair retains a historical record of alcohol and drug intake by embedding biomarkers in the strands as they grow. When hair is cut close to the scalp, it can reveal drug and alcohol consumption for up to around 90 days. Collecting hair is straightforward, hard to manipulate, and convenient to transport.

Gathering a sample of 1.5 inches from roughly 200 strands near the scalp provides about 100mg of hair, suitable for both preliminary screening and confirmatory testing. For assessments like EtG, additional screenings, or those exceeding 10 panels, it is advisable to use 150mg of hair. We suggest using a jeweler’s scale for precise weighing of the sample. If scalp hair isn't accessible, an equivalent amount of body hair may be used. 'Head hair' specifically refers to hair from the scalp, whereas 'body hair' includes all other types such as facial and axillary hair.

Process Overview

The lab processing for a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially integrated into a laboratory's tracking system. This step includes checking if the sample is appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and inputting any supplementary information absent from an electronic chain of custody system.

Screening is a preliminary rapid test for the presence of substances. While it’s a practical measure to dismiss drug use in most samples economically, a positive screening outcome warrants a confirmatory test for validity, especially in legal contexts. Presumptive positives from Screening necessitate further confirmation.

In cases of presumptive positivity during Screening, additional hair is extracted from the original sample and readied for the Extraction phase. Here, drugs are separated from the hair at much lower concentrations compared to other techniques like urine or oral fluid tests, making hair drug testing a complex method to administer.

Confirmation of any positive screening requires techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples testing presumptive positive are cleansed as required. The comprehensive lab operation from Accessioning through Confirmation is evaluated in line with both CAP (College of American Pathologists) Hair specifications and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have a shorter detection duration.
• Challenging to tamper with: Tampering with hair drug tests is exceptionally tough, enhancing result accuracy.
• Documents historical usage: It can reflect drug use patterns over time, rather than just recent consumption.

Limitations:

• Inability to detect recent intake: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug testing is generally costlier than other testing techniques.
• Result fluctuations: Elements such as hair color and individual differences in growth can influence drug metabolite concentrations in hair.

Note: The so-called "hair follicle test" actually examines the strand of hair itself, 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. 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.
