Hair Follicle Drug Testing - Otter, MT

What it is, How it works

Hair analysis is increasingly recognized as an effective tool for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug use by embedding biomarkers within the hair fibers as they grow. By obtaining a sample close to the scalp, hair can reveal up to a 3-month period of alcohol and drug use. The collection process is straightforward, challenging to alter, and convenient to transport.

To obtain the ideal sample of 100mg, approximately 200 strands of hair (or the thickness of a #2 pencil) measuring 1.5 inches from the scalp should be used for testing. For examinations like EtG, additional assessments, or tests exceeding 10 panels, it is advised to use a sample weighing 150mg. Utilizing a jeweler’s scale is recommended for accurate measurement. If scalp hair isn’t available, a comparable quantity of body hair can be used. The term 'head hair' exclusively refers to scalp hair, while 'body hair' encompasses all other hair types (e.g., facial, axillary).

Process Overview

The laboratory process of a drug test encompasses four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is recorded in the laboratory’s system. This process involves ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any missing information not captured by an electronic chain of custody.

Screening is a preliminary examination for identifying substances of abuse. While this provides an economical method to screen most samples for drug usage, a positive result necessitates further validation for legal admissibility. All samples yielding a presumptive positive in Screening require a subsequent confirmation.

For samples with potential positive results in the Screening phase, additional hair is extracted from the original sample for the Extraction process. During this phase, substances are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), highlighting the complexity of hair drug analysis.

Confirmation of a positive screening outcome is achieved through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected to be positive undergo a wash before confirmation, as needed. The comprehensive laboratory sequence, from Accessioning to Confirmation, undergoes an audit under both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair analysis can detect drug usage up to 90 days, while urine tests offer a shorter duration for detection.
• Difficult to falsify: Hair drug tests are highly accurate as they are difficult to tamper with.
• Historical insight: It allows for tracking drug use patterns over time, instead of just recent usage.

Limitations:

• Delayed detection: Drugs take around 5-7 days to be detectable in hair after use.
• Expense: Generally, hair drug tests come at a higher cost compared to alternative testing methods.
• Result variations: Factors like hair color and individual hair growth rates may influence the drug metabolite levels in hair.

Note: Although commonly termed as "hair follicle tests", the procedure actually 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.
