Hair Follicle Drug Testing - Seminary, MS

What it is, How it works

The assessment of substances in hair is now acknowledged as an effective means for identifying drug and alcohol use. Hair captures a prolonged history of substances as it ensnares biomarkers within its developing strands. Collected close to the scalp, hair offers nearly a 90-day window for detecting alcohol and drugs. The collection process is straightforward, resisting tampering to an extent, and is conveniently shippable.

A 1.5-inch length of roughly 200 hair strands (similar in thickness to a #2 pencil) cut nearest the scalp yields 100mg, which is the optimal quantity for both screening and verification. For tests like EtG, extended panels above ten, 150mg is advised. The weight of the specimen should be measured on a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair can be used. 'Head hair' refers specifically to scalp hair, while 'body hair' denotes other hair categories (such as facial, axillary, etc.).

Process Overview

The laboratory processing for a drug test encompasses four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is incorporated into a lab’s system. This involves checking that samples are sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any pending data entries absent from an electronic chain of custody system.

Screening involves a cursory assessment for substances of concern. Though it's a cost-wise means to exclude drug use from the majority of samples, confirmation is needed for a positive screen to hold in legal settings. Any sample that tests positive in the Screening phase demands additional confirmation.

If a sample tests positive in Screening, more hair is extracted from the original specimen and readied for Extraction. Drugs are isolated from hair at a markedly lower concentration compared to other approaches (e.g., urine or saliva), highlighting the complexity of hair drug testing as a methodology.

Confirmation for any positive result from the screening is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that initially test positive are cleansed before confirmation as needed. The progression from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use over a 90-day span, surpassing the shorter detection span of urine tests.
• Challenging to deceive: The difficulty in cheating a hair drug test enhances its accuracy.
• Historical insights: It provides a chronicle of substance use across time, unlike merely indicating recent consumption.

Limitations:

• Lacks recent use detection: Drugs take around 5-7 days to become noticeable in hair.
• Expense: Hair drug tests generally incur higher costs compared to alternate testing methods.
• Result variability: Factors like hair color and personal variations in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the assessment examines 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. 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
