Hair Follicle Drug Testing - Long Beach, MN

What it is, How it works

Hair screening is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended historical record of drinking and substance use by embedding biomarkers within the hair strand's fibers as it grows. Collected near the scalp, hair can reveal substance use over a period stretching up to around three months. Collecting hair is straightforward, poses challenges for tampering, and is convenient to transport.

A 1.5-inch hair sample consisting of roughly 200 strands (comparable to a #2 pencil's thickness) from the scalp yields 100mg of hair, which is the preferred amount for testing and confirmatory analysis. For EtG, additional tests, and/or screenings exceeding 10 panels, a 150mg sample is advised. It is recommended to use a jeweler’s scale for weighing the sample. In cases where scalp hair is absent, a comparable amount of body hair can be used. Here, head hair specifically pertains to scalp hair, while body hair includes all other types (such as facial or axillary hair).

Overview of the Process

The laboratory workflow for processing a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a laboratory’s framework. This process ensures the sample was appropriately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and concludes any additional data entry beyond what an electronic chain of custody system provides.

Screening provides an initial rapid check for substances of abuse. Although screening is a budget-friendly method mainly used to rule out drug presence in most samples, a positive screen result needs verification to be court-admissible. Samples indicative of a positive result in screening need confirmatory testing.

Should a sample appear positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. Here, substances are extracted from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening a particularly challenging method to execute.

Confirming positive screening outcomes involves using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned as necessary before confirmation. The comprehensive lab process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair guidelines and meets ISO / IEC 17025 accreditation criteria.

Benefits of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days, compared to the shorter detection span of urine tests.
• Proof against tampering: Hair drug tests are challenging to bypass, ensuring more reliable outcomes.
• Records past patterns: They can reveal drug use trends over time rather than merely recent usage.

Challenges:

• Inability to catch recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug testing is often costlier than other testing approaches.
• Variability in outcomes: Variables like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: The term "hair follicle tests" is commonly used, though the analysis actually examines the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
