Hair Follicle Drug Testing - Colon, MI

What it is, How it works

Utilizing hair testing is observed as a significant method for detecting drug and alcohol consumption. Hair offers an extended history of alcohol and drug usage by encapsulating biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair may present up to about a 3-month window for detecting alcohol and drugs. Hair is uncomplicated to gather, relatively resistant to tampering, and simple to send.

A sample measuring 1.5 inches consisting of about 200 hair strands (approximately the girth of a #2 pencil) nearest the scalp yields 100mg of hair, the perfect specimen for screening and confirmation processes. For EtG, additional tests, and/or panels exceeding 10, 150mg of the hair specimen is advised. We suggest weighing the hair using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent amount of body hair can be collected. When addressing head hair, it specifically pertains to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the preliminary steps of processing a sample in a laboratory's system. It involves ensuring the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. Though Screening is cost-efficient to eliminate drug use for most samples, any positive screenings require verification to stand in court. Samples with presumptive positives in Screening necessitate a follow-up confirmation.

For any sample that shows a presumptive positive at the Screening stage, more hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than in methodologies such as urine or oral fluid; thus, making hair drug screening the most challenging method to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS confirms any positive screening result. All presumptive positive samples undergo a wash before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests with a shorter detection timeframe.
• Difficult to deceive: Cheating a hair drug test is extremely challenging, enhancing the results' accuracy.
• Offers historical insights: It can demonstrate a timeline of drug usage over a period, rather than just recent use.

Drawbacks:

• Recent use undetectable: It requires about 5-7 days for drugs to be discernible in hair.
• Expensive: Hair drug tests generally incur higher costs compared to alternate drug testing methods.
• Results variability: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Often called “hair follicle tests”, the analysis is conducted on the hair strand, not on the hair 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.
