Hair Follicle Drug Testing - Columbia Falls, MT

What it is, How it works

Hair analysis is increasingly recognized as an effective means for uncovering drug and alcohol consumption. Hair captures a history of alcohol and drug use by embedding biomarkers within the hair's fibers as it grows. If collected near the scalp, hair can indicate use over nearly a three-month period for alcohol and drugs. Hair is easy to gather, not easily tampered with, and convenient to transport.

A hair sample measuring 1.5 inches containing around 200 strands (approximately the diameter of a #2 pencil) nearest to the scalp delivers 100mg of hair, considered the optimal amount for analysis. When testing for EtG, additional analytes, or panels exceeding ten, a 150mg specimen is advisable. Utilizing a jeweler’s scale to measure the sample is recommended. If scalp hair is not available, the collection of a similar quantity of body hair is an option. It should be noted that head hair refers specifically to scalp hair. Body hair includes all other hair such as facial and axillary.

Process Overview

The primary laboratory steps in drug test analysis encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase where a sample is integrated into the lab's system. This step involves checking that the sample's seal and shipping were intact, issuing a unique LAN (Laboratory Accessioning Number), and completing any necessary manual data entry not captured by an electronic chain of custody.

Screening is a preliminary examination for drug presence. Although Screening is a cost-efficient approach to exclude drug use for many samples, a positive Screen result must be validated to ensure legal admissibility. Samples that test presumptively positive need further confirmation.

For samples that are presumptively positive during Screening, additional hair is extracted from the primary sample for the Extraction process. During this phase, drug substances are drawn from hair at significantly lower concentrations than methods like urine or saliva testing, making hair drug screening one of the most complex processes to conduct.

Positive screening results require validation through GC/MS, GC/MS/MS, or LC/MS/MS. Before proceeding to confirmation, presumptive positive samples are cleansed as appropriate. The full lab process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that offer a shorter detection time frame.
• High resistance to tampering: The results of a hair drug test are more reliable as they are hard to alter.
• Longitudinal data provision: Offers insight into drug usage trends over time rather than immediate use results.

Drawbacks:

• Inability to detect recent consumption: Drugs require roughly 5-7 days post-use to become traceable in hair.
• Expense: Hair drug testing typically incurs higher costs compared to alternate testing methods.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Despite commonly being called "hair follicle tests", these tests analyze the hair strands rather than the follicles 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.
