Hair Follicle Drug Testing - Poso Park, CA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It offers a historical view of substance use by capturing biomarkers within the growing hair fibers. When hair is gathered near the scalp, it can reveal alcohol and drug use over a period of up to three months. Hair collection is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch portion consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the preferred amount for examination and validation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is suggested. It's advised to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair might be used. The term head hair specifically pertains to scalp hair, while body hair includes all other types (facial, axillary, and so on).

Process Overview

The drug testing process in a lab consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is introduced into the laboratory's system, ensuring it was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody protocol.

Screening is a preliminary assessment for drug presence. Although it is cost-efficient for ruling out drug use in most samples, a positive outcome needs confirmation to be considered valid in a legal context. Samples that are preliminarily positive during Screening require further confirmation.

In the event of a presumptive positive result in the Screening phase, additional hair is taken from the original sample for the Extraction process. Here, drugs are isolated from hair at a much lower concentration compared to other methods like urine or saliva tests, making hair drug testing the most complex to execute.

GC/MS, GC/MS/MS, or LC/MS/MS is employed for confirming any positive screening findings. All samples deemed presumptively positive are washed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair endorsement and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug testing can reveal drug use for up to 90 days, unlike urine tests which have a more limited detection timeframe.
• Difficulty to cheat: Tampering with a hair drug test is highly challenging, thus increasing result accuracy.
• Provides historical data: Offers a drug use pattern over time, not merely recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair in about 5-7 days.
• Cost: Generally, hair drug tests are more expensive than other testing methods.
• Variations in results: Hair color and individual differences in hair growth can affect metabolite levels in the hair.

Note: Despite often being termed "hair follicle tests", the examination targets 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.
