Hair Follicle Drug Testing - Rye, AZ

What it is, How it works

Recognized as a potent means for detecting alcohol and drug usage, hair testing offers a comprehensive long-term record by encapsulating biomarkers within the strands as they grow. Hair, when cut near the scalp, gives an alcohol and drug detection period of up to around 90 days. It's easy to collect, challenging to alter, and straightforward to transport.

Collecting a 1.5-inch sample of approximately 200 hair strands (about #2 pencil thickness) from near the scalp yields 100mg of hair, the prime sample for both screening and validation. A specimen of 150mg is recommended for tests involving EtG, add-ons, and surpassing 10 panels. Utilizing a jeweler’s scale is advisable for weighing the sample. If scalp hair is absent, equivalent body hair can be gathered. 'Head hair' strictly denotes scalp hair, while 'body hair' references all other hair types (e.g., facial, axillary).

Process Overview

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

In Accessioning, the sample undergoes initial processing within the lab's framework. This step involves confirming the proper sealing and shipment of the sample, granting it a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.

Screening delivers a preliminary evaluation to determine the presence of drugs. Although Screening efficiently excludes drug consumption in most samples cost-effectively, any positive screen necessitates confirmation to be court-admissible. Samples yielding presumptive positives during Screening require additional confirmation.

Should a sample exhibit a presumptive positive during Screening, further hair is extracted from the initial sample for the Extraction phase. Here, drug traces are drawn out at much lower levels than other methods (such as urine or oral fluid), making hair drug screening notably intricate.

The Confirmation of any positive screening outcome occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as necessary. The complete lab process from Accessioning through Confirmation adheres to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use for up to 90 days, outlasting the shorter detection period of urine tests.
• Reduced cheating potential: Cheating a hair drug test is highly impractical, ensuring greater precision.
• Delivers historical insights: This method reveals usage patterns over time rather than recent consumption alone.

Limitations:

• Inability to detect recent usage: Drugs require approximately 5-7 days to be detectable in hair.
• Higher cost: Hair drug tests usually incur greater expenses than alternative drug-testing methods.
• Result variations: Drug metabolite concentration in hair can be swayed by factors like hair color and individual growth differences.

Note: Despite the term "hair follicle tests," the procedure examines the hair strand, not the scalp's hair follicle.

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.
