Hair Follicle Drug Testing - Sandy, OR

What it is, How it works

Hair testing is regarded as an effective means for identifying drug and alcohol consumption. It offers a prolonged history of alcohol and drug use by capturing biomarkers within the hair fiber matrix. When extracted near the scalp, hair can provide an approximate 3-month period of detection for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and convenient for shipping.

A 1.5-inch hair segment sampled from around 200 strands (similar to a #2 pencil thickness) nearest to the scalp will yield 100mg of hair, the optimal portion for preliminary and confirmatory testing. For EtG, additional analytes, and/or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair is inaccessible, an equivalent quantity of body hair is acceptable. Here, head hair refers exclusively to scalp hair, whereas body hair includes all other types (such as facial, axillary, etc.).

Process Overview

The core stages in lab processing for a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a sample within a lab's workflow. This phase ensures the sample's seal and shipment were intact, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional manual data input not captured via an e-chain of custody system.

Screening is an initial expedited test for detecting drug misuse. Although an economical technique to exclude drug usage for most samples, a positive screen mandates verification for court legitimacy. All samples showing a preliminary positive in Screening necessitate further confirmation.

If the Screening phase results in a presumptive positive, additional hair is extracted from the initial sample for the Extraction process. During this stage, drugs are isolated from hair at a significantly lower concentration than other methods (e.g., urine or saliva), making hair drug testing the most complex technique.

Confirmation of any screening positives is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo necessary pre-confirmation cleansing. The entire lab process from Accessioning through Confirmation is assessed under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug testing can reveal drug usage history for up to 90 days, unlike urine tests that have shorter detection periods.
• High difficulty to falsify: Cheating a hair drug test is very challenging, thus enhancing accuracy.
• Historical usage insight: It reveals a temporal pattern of drug consumption, beyond just recent usage.

Limitations:

• Inability to identify recent use: Drugs are detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Hair color variations and individual hair growth differences can impact drug metabolite concentrations.

Note: While commonly called "hair follicle tests", the analysis focuses on 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.
