Hair Follicle Drug Testing - San Juan, NM

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. This methodology captures long-term drug and alcohol usage by storing biomarkers within the hair fibers as they grow. By collecting hair near the scalp, it's possible to achieve a detection span of up to roughly three months for alcohol and various drugs. Collection is straightforward, it's somewhat resistant to tampering, and shipping is uncomplicated.

Securing a segment of hair 1.5 inches long, roughly equivalent to 200 strands (similar in width to a #2 pencil), from the scalp will provide 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, or panels above 10, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair is not available, an equivalent amount of body hair can be used instead. "Head hair" references scalp hair solely. "Body hair" encompasses all other varieties such as facial and axillary hair.

Process Overview

The four essential stages in lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of incorporating a sample into a laboratory's system. This involves checking that the sample was sealed and transported appropriately, designating a random LAN (Laboratory Accessioning Number), and finishing any additional data input not offered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug abuse. While this is a cost-efficient method to exclude drug usage for most samples, a positive outcome in screening must be verified to be legally valid. Samples showing presumptive positive results in Screening require subsequent verification.

Should a presumptive positive be found during Screening, more hair is retrieved from the original specimen to prepare for Extraction. During this step, drugs are extracted from hair at significantly lower concentrations compared to other methods like urine or oral fluid, contributing to the challenging nature of hair drug analysis.

Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples with presumptive positives undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is reviewed according to both the CAP (College of American Pathologists) Hair standards and the accreditation under ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage up to 90 days, compared to urine tests with a shorter detection timeframe.
• Challenging to manipulate: Hair drug tests are quite difficult to falsify, enhancing the reliability of results.
• Historical usage data: They can reveal a history of drug use over time, not merely recent activity.

Limitations:

• Inability to detect recent use: There is a 5-7 day timeframe before drugs become detectable in hair.
• Expense: Generally, hair drug tests are costlier than alternative drug testing methods.
• Result variability: Drug metabolite concentration can be influenced by differences in hair color and individual hair growth rates.

Note: Despite being commonly called "hair follicle tests", the analysis specifically examines the hair strand and 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.
