Hair Follicle Drug Testing - Rockledge, AL

What it is, How it works

Hair testing has gained recognition as an effective method for identifying the use of drugs and alcohol. Hair retains a record of alcohol and drug intake by embedding biomarkers within the structure of the growing hair. When cropped near the scalp, hair can present a detection window extending up to approximately three months for alcohol and drugs. The collection of hair samples is straightforward, challenging to tamper with, and convenient for transport.

A 1.5-inch sample of approximately 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and screens exceeding ten panels, a 150mg specimen is advised. Using a jeweler’s scale to weigh the specimen is recommended. In the absence of scalp hair, a corresponding amount of body hair can be used. References to head hair are specific to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The processing of a drug test in the laboratory consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a laboratory's system. It involves checking that the sample was correctly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and entering any supplementary data that is not included in an electronic chain of custody system.

Screening consists of a preliminary assessment for drugs of abuse. While Screening offers a cost-effective way to rule out drug use in the majority of samples, a positive result requires confirmation for it to be legally permissible. Samples that show presumptive positivity in Screening necessitate additional confirmation.

Should a sample be presumptively positive at the Screening phase, more hair is taken from the main specimen for preparation in the Extraction phase. Here, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most intricate methods to implement.

Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples showing presumptive positives undergo washing prior to confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to deceive: It is notably difficult to cheat a hair drug test, enhancing the accuracy of results.
• Supplies historical data: This method provides a record of drug use over a period, rather than just recent consumption.

Limitations:

• Cannot detect recent use: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug tests often cost more compared to other drug testing techniques.
• Result variability: Elements like hair color and differences in individual hair growth can impact the concentration of drug metabolites in the hair.

Note: Although commonly known as "hair follicle tests", the actual analysis targets the hair strand and 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.
