Hair Follicle Drug Testing - Freedom Acres, AZ

What it is, How it works

The use of hair testing has become recognized as a significant means for identifying drug and alcohol consumption. Hair captures a prolonged record of drugs and alcohol by embedding biomarkers within the strands of growing hair. When strands are harvested near the head, this method can deliver a detection period of nearly three months for alcohol and various drugs. Collecting hair is straightforward, challenging to tamper with, and convenient for transportation.

A sample length of 1.5 inches, comprising around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp, yields about 100mg of hair, which is the preferred quantity for both screening and verification. If additional tests like EtG or tests beyond 10 panels are required, 150mg of the sample is advised. Measuring should be done using a jeweler’s scale. Where scalp hair cannot be sourced, an equivalent measure of body hair can be taken. References to head hair indicate only scalp hair, while body hair encompasses all other hair varieties (e.g., facial, axillary).

Process Overview

The laboratory processing of drug test results involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial introduction of a sample into the lab’s system. It involves ensuring that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from an electronic chain of custody.

Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening is a cost-effective method for excluding drug use in most samples, a positive screen needs subsequent validation to hold in legal settings. Any samples that are preliminarily positive in Screening require further confirmation.

When a sample tests presumptively positive in the Screening stage, additional hair is extracted from the initial specimen for the Extraction stage. In Extraction, drugs are isolated from hair at substantially lower concentrations than found in other testing methods (like urine or oral fluid), which makes hair drug testing the most intricate methodology to execute.

Confirmation of any positive Screenings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are cleansed prior to confirmation as necessary. The complete laboratory workflow from Accessioning to Confirmation is assessed under both the CAP Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace drug use for as long as 90 days, unlike urine assessments that have a more limited detection period.
• Resistant to manipulation: Manipulating a hair drug test is very challenging, hence results are more trustworthy.
• Provides historical insights: It presents a timeline of drug use over extended periods, beyond just recent use.

Limitations:

• Unable to identify recent use: Approximately 5-7 days are required before drugs manifest in hair.
• Expense: Hair drug screenings generally incur higher costs than alternative testing methods.
• Variability in outcomes: Elements such as hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often labeled as "hair follicle tests", the evaluation concerns the hair strand rather than the follicle itself 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
