Hair Follicle Drug Testing - Nuevo, CA

What it is, How it works

Hair testing is recognized as an effective mechanism for identifying drug and alcohol consumption. Hair records a timeline of alcohol and drugs by embedding biomarkers within its growing strands. When gathered near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch sample with around 200 hair strands (approximately the width of a #2 pencil) near the scalp yields 100mg, ideal for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for precise measurement. If scalp hair is inaccessible, a proportional amount of body hair can be sourced. Reference to head hair pertains solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The key phases in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial incorporation of a sample into a laboratory’s system, ensuring the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input absent from an electronic chain of custody system.

Screening provides an initial, rapid assessment for drugs of abuse. While effective in ruling out drug usage across most samples, a positive screen warrants confirmation for court admissibility. Samples with a presumptive positive in Screening require subsequent confirmation.

If Screening yields a presumptively positive result, additional hair is extracted from the initial sample for Extraction. This stage involves extracting drugs from hair at a notably lower concentration compared to other methods (ex. urine or oral fluid), making hair drug screening a complex methodology.

Confirmation of any positive screening is executed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Detects drug use up to 90 days, unlike urine tests with shorter detection periods.
• Hard to deceive: Cheating a hair drug test is arduous, enhancing result accuracy.
• Delivers historical usage data: Offers a usage pattern over time, not solely recent use.

Limitations:

• Inability to detect recent use: Requires roughly 5-7 days for drugs to be visible in hair.
• Expense: Generally, hair drug tests cost more than other drug testing methods.
• Result variability: Hair color and individual hair growth variations can impact drug metabolite levels in the hair.

Note: Commonly termed as "hair follicle tests", the analysis pertains to 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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
