Hair Follicle Drug Testing - Saint Marys, AK

What it is, How it works

Hair assessment is now recognized as an influential means for detecting drug and alcohol consumption. Hair captures a long-lasting account of alcohol and other drugs by embedding biomarkers within the strands’ fibers as they grow. If taken near the scalp, hair can show an alcohol or drug presence for up to roughly 3 months. Hair collection is straightforward, hard to tamper with, and simple to send.

A sample of 1.5 inches, containing about 200 hair strands (around the dimensions of a #2 pencil) nearest the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG tests, additional checks, and/or those exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. If hair from the head isn’t available, an equivalent volume of body hair can be used. Head hair refers specifically to scalp hair. All other hair types (facial, axillary, etc.) are classified as body hair.

Process Overview

The primary stages involved in analyzing a drug test in a laboratory setting include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab's system. This step ensures the sample is correctly sealed and transported and that a random LAN (Laboratory Accessioning Number) is allocated, along with any extra data entry needed beyond what an electronic chain of custody system supplies.

Screening involves a preliminary swift drug abuse check. While it’s an economical way to exclude drug use in most cases, a positive outcome requires confirmation to stand in a legal setting. Any presumptively positive samples from Screening need a follow-up confirmation.

If a sample marks presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. At this juncture, drugs are retrieved from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

The Confirmation step for any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation, as needed. The complete lab process from Accessioning to Confirmation adheres to the standards set by the CAP (College of American Pathologists) under their Hair designation and complies with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can uncover drug consumption for up to 90 days, unlike urine tests with shorter detection ranges.
• Minimal chance of deceit: Hair drug tests are notably hard to manipulate, enhancing accuracy in results.
• Reveals usage history: It offers insights into drug patterns over time, beyond just recent use.

Limitations:

• Cannot identify recent use: Drugs typically take about 5-7 days to become detectable in hair.
• Expense: Hair drug assessments generally cost more than alternative methods.
• Result variations: Factors such as hair color and individual hair growth differences may impact drug metabolite concentration in the hair.

Note: Typically termed as "hair follicle tests", this analysis examines the hair strand 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.
