Hair Follicle Drug Testing - Leonard, MI

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair captures a comprehensive history of substance use by embedding biomarkers within its growing strands. When taken close to the scalp, hair can indicate drug and alcohol usage over an approximate three-month period. Its collection is easy, it's relatively hard to tamper with, and it can be shipped with ease.

A 1.5-inch sample comprising around 200 hair strands (roughly the dimensions of a #2 pencil) nearest to the scalp will yield 100mg of hair, the recommended sample size for screening and validation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample size is suggested. Using a jeweler's scale for weighing is advisable. If scalp hair is unavailable, an equivalent amount of body hair is acceptable. When mentioning head hair, we imply scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The core stages in lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses integrating a specimen into a lab's system. This involves ensuring the sample was correctly sealed and posted, issuing a unique LAN (Laboratory Accessioning Number), and completing any extra data input missing from an electronic chain of custody record.

Screening is a preliminary swift inspection for potential drug use. Although Screening is a cost-efficient method to dismiss drug usage in most specimens, a positive screening result must be authenticated for legal admissibility. Samples that are tentatively positive in Screening necessitate further confirmation.

In cases of presumptive positive results during Screening, additional hair is retrieved from the initial sample and prepped for Extraction. This phase involves drawing out drugs from hair at significantly lower concentrations than alternative methods (e.g., urine or saliva), underscoring why hair drug testing is notably challenging.

Validating any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS processes. All samples indicating potential positivity are cleaned before confirmation as necessary. The entire lab procedure, from Accessioning through Confirmation, is subject to evaluation under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection capability: Hair drug screening identifies drug consumption for as long as 90 days, unlike urine screenings with more limited detection spans.
• Resistance to manipulation: Hair drug tests are notably difficult to manipulate, thereby enhancing result accuracy.
• Insight into substance history: It provides insight into drug use patterns over time, beyond immediate consumption.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to show up in hair samples.
• Expense: Hair drug examinations often incur higher costs compared to other drug test techniques.
• Result variability: Elements such as hair pigmentation and individual growth variation can influence metabolite concentration in hair.

Note: Despite being popularly called "hair follicle tests," the analysis targets the strand itself rather than 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. 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.

In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
