Hair Follicle Drug Testing - Welcome, LA

What it is, How it works

The analysis of hair samples has grown in prominence as an effective means for identifying drug and alcohol consumption. Hair archives a prolonged consumption history of alcohol and various drugs by holding onto biomarkers within the fibers of the growing strand. When the hair is clipped near the scalp, it can reveal a detection span of up to about three months for alcohol and other substances. Hair collection is uncomplicated, somewhat resistant to tampering, and straightforward to dispatch.

A 1.5-inch section comprising roughly 200 hair strands (comparable to a #2 pencil thickness) nearest to the scalp furnishes 100mg of hair, which is the optimal quantity for testing and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler’s scale for weighing the sample. If scalp hair is unavailable, an equivalent quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other varieties of hair (such as facial and axillary).

Process Overview

The laboratory processing of drug test results consists of four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a laboratory’s framework. This step involves ensuring that the sample was correctly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry that an electronic chain of custody system does not provide.

Screening consists of an initial rapid assessment for drugs of abuse. Although Screening is an economical approach to exclude drug usage for the majority of samples, a positive screen requires confirmation to be valid in court. Any sample indicating a potential positive during Screening necessitates a secondary confirmation.

If a sample appears potentially positive at the Screening stage, more hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are drawn out from the hair at significantly lower concentrations than in other techniques (such as urine or oral fluid), making hair drug screening the most challenging technique to conduct.

Confirmation of any positive Screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples appearing presumptively positive undergo washing before confirmation, as necessary. The entire laboratory sequence from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair certification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can identify drug usage for up to 90 days, contrary to urine tests which have a briefer detection range.
• Challenging to manipulate: It is exceedingly challenging to manipulate a hair drug test, thereby making the outcomes more dependable.
• Yields historical insight: It can exhibit a pattern of drug consumption over time, rather than recent usage alone.

Limitations:

• Inability to detect recent usage: It requires approximately 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests typically incur greater costs compared to other drug testing techniques.
• Discrepancies in outcomes: Factors like hair color and individual disparities in hair growth may influence the concentration of drug metabolites in the hair.

Note: While frequently called "hair follicle tests", the procedure examines 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.

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. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
