Hair Follicle Drug Testing - Rawlings, MD

What it is, How it works

Hair testing is recognized as an effective instrument for identifying alcohol and drug consumption. Hair offers an extensive timeline by embedding biomarkers within the strands of the growing hair. When obtained near the scalp, it can provide a detection span of up to three months for alcohol and drugs. Hair collection is easy, difficult to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (similar to the width of a #2 pencil) nearest to the scalp, generates 100mg of hair, the preferred amount for both screening and verification. For EtG, additional tests, or panels above 10, 150mg of the sample is advised. It's suggested to weigh the sample on a jeweler’s scale. If no scalp hair is present, an equivalent amount of body hair is suitable. When mentioning head hair, it is specific to scalp hair alone. Body hair includes all other types such as facial and axillary hair.

Process Overview

The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary processing of a sample within a lab’s framework. It involves checking that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing other data entries absent from the electronic chain of custody system.

Screening offers an initial rapid assessment for drug abuse. While it cost-effectively rules out drug use in most samples, a positive result must be confirmed for court acceptance. Samples with presumptive positives require additional confirmation.

A presumptive positive result in Screening leads to additional hair being extracted from the same sample for further Extraction. During this phase, drugs are isolated from hair in significantly lower concentrations than other approaches (such as urine or oral fluid), explaining the complexities of hair drug screening.

Confirmation of any positive result in screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all presumptive positives undergo washing as necessary. The entire process from Accessioning to Confirmation is overseen following both the CAP (College of American Pathologists) Hair designation and accreditation 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, surpassing the shorter span of urine tests.
• Hard to manipulate: Cheating a hair drug test is quite challenging, enhancing accuracy.
• Offers historical insight: It reveals a drug use pattern over time, not just recent activity.

Limitations:

• No recent use detection: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Result variability: Characteristics such as hair color and individual hair growth rates can alter metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis pertains to the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests in Rawlings, MD surpass urine tests in several ways. The detection accuracy is higher due to the longer time substances remain in hair.

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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
