Hair Follicle Drug Testing - Clyde, CA

What it is, How it works

Hair analysis has become recognized as a robust technique for determining drug and alcohol consumption. Hair offers a historical record of alcohol and drug intake by capturing biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can offer up to around a 3-month detection period for substances. Hair collection is straightforward, relatively tough to adulterate, and simple to ship.

A 1.5-inch segment containing roughly 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is advised. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair can't be obtained, a similar amount of body hair may be used. References to head hair pertain only to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial handling of a sample entering a lab’s system. This step verifies that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finishes any additional data entry absent from an electronic chain of custody system.

Screening conducts an initial rapid assessment of drugs of abuse. While Screening is a cost-saving approach for ruling out drug usage in most samples, any positive screening necessitates confirmation to be valid in court. Samples showing positive results in Screening require further confirmation.

If a sample shows a positive indication in the Screening phase, more hair from the original sample is extracted and prepared for Extraction. In this phase, substances are extracted at much lower concentrations than with other methods (e.g., urine or oral fluid), making hair drug screening a highly challenging methodology to execute.

Any positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned as necessary before confirmation. The complete laboratory workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 benchmarks.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, surpassing the shorter detection period of urine tests.
• High difficulty to falsify: Altering a hair drug test is very challenging, increasing result accuracy.
• Offers historical insight: It provides a pattern of substance use over time, not just recent consumption.

Drawbacks:

• Inability to identify recent consumption: Drugs typically become detectable in hair 5-7 days post-use.
• Expense: Hair drug tests usually have a higher cost than other drug test types.
• Result variations: Attributes like hair color and individual hair growth differences can impact drug metabolite concentrations in the hair.

Note: Often labeled as "hair follicle tests", the analysis targets the hair strand 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. 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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
