Hair Follicle Drug Testing - Warrior, AL

What it is, How it works

Recognized as a potent method for identifying alcohol and drug use, hair testing offers a thorough timeline by embedding biomarkers within the fibers of the hair as it grows. Collected near the scalp, it provides up to a 3-month detection span for substances like alcohol and drugs. The collection process is straightforward, challenging to tamper with, and simple to transport.

When obtaining a specimen, a 1.5-inch segment from approximately 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the preferred quantity for both screening and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent portion of body hair is permissible. "Head hair" exclusively refers to scalp hair, whereas "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for evaluating a drug test sample consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial intake of a sample into the lab's system. This process entails verifying the proper sealing and shipment of the sample, assigning it a random Laboratory Accessioning Number (LAN), and completing any extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary and economical method to identify potential drug use in most samples. To ensure the results are legally valid, any positive screening outcome must undergo further confirmation. Samples with presumptive positive results in Screening require additional confirmation.

For samples flagged as presumptively positive during Screening, hair is further extracted from the original sample for the Extraction phase. In this stage, drugs are drawn from the hair at much lower levels compared to other methodologies such as urine or oral fluid, making hair drug screening particularly challenging.

Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples classified as presumptive positives are cleansed as necessary before confirmation. The oversight of the entire lab process from Accessioning to Confirmation is conducted under both the College of American Pathologists (CAP) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests detect substance use for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficult to deceive: The test's accuracy is heightened due to the difficulty of cheating a hair drug test.
• Chronic usage data: It reveals patterns of drug use over time, rather than just recent consumption.

Limitations:

• Inability to detect recent usage: Drug presence in hair is typically detectable after 5-7 days.
• Expense: Hair drug testing tends to be pricier than alternative drug testing techniques.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations.

Note: Despite being commonly termed as "hair follicle tests," these tests assess the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outperform urine testing in Warrior, AL? Hair tests are more effective due to their extended detection periods and higher accuracy. Unlike urine tests, which only detect recent drug use, hair tests provide a comprehensive analysis over a longer timeframe.

Extended Detection Window

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.
