Hair Follicle Drug Testing - Macedonia, AL

What it is, How it works

Hair testing has emerged as an effective means for identifying the use of drugs and alcohol. Hair offers an extended historical record of alcohol and drug use by capturing biomarkers within the fibers of the hair as it grows. When snipped near the scalp, hair can offer an alcohol and drug detection span of up to roughly 3 months. Collecting hair is straightforward, not easy to tamper with, and convenient to transport.

A sample measuring 1.5 inches of approximately 200 hair strands (comparable to a #2 pencil's thickness) nearest the scalp yields 100mg, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, a proportional amount of body hair can be gathered. When mentioning head hair, it exclusively refers to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial filing of a sample into a lab’s system. This step involves confirming the sample's secure sealing and transport, allocating an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody framework.

Screening conducts a preliminary rapid assessment for drug misuse. Although Screening is an economical method for negating drug use in most samples, a positive screening must be validated to stand in court. Any samples deemed presumptively positive during Screening necessitate further confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are separated from hair at a concentration significantly lesser than in other systems (e.g., urine or saliva), rendering hair drug screening the most intricate methodology to execute.

For confirming any positive screening outcome, technologies such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. All samples that test presumptively positive undergo washing prior to confirmation as required. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more limited detection timeframe.
• Hard to evade: Cheating a hair drug test is exceedingly challenging, enhancing result accuracy.
• Offers chronological data: It can chart a timeline of drug use over a period, not solely recent activities.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests typically incur greater costs compared to alternative testing methods.
• Result variability: Elements like hair color and personal differences in hair growth may influence drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests", the analysis is performed on the hair strand, not the follicle under 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.
