Hair Follicle Drug Testing - Highwoods, IN

What it is, How it works

Hair analysis has gained traction as an efficient means for identifying drug and alcohol consumption. The fibers of growing hair strands capture biomarkers, providing a timeline of substances in the body. Hair taken near the scalp offers roughly a three-month window for detecting alcohol and drugs. It's easy to collect, relatively hard to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (aproximately equating to the diameter of a #2 pencil) from the scalp provides 100mg of hair, which is ideal for assessment and validation. For EtG, add-ons, and screenings above 10 panels, 150mg of the sample is preferred. It's advisable to use a jeweler’s scale for weighing the sample. Should scalp hair be inaccessible, an equivalent quantity of body hair can be utilized. When discussing head hair, we mean scalp hair exclusively. Body hair pertains to any other hair type (facial, axillary, etc.).

Process Overview

The primary procedures in processing a drug test sample within a laboratory encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of inducting a sample into the laboratory system. This consists of ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not available through an electronic chain of custody.

Screening is an initial assessment for substances of misuse. Though Screening provides a cost-efficient way to exclude drug use for the majority of samples, a positive result necessitates Confirmation for court acceptance. Any samples marked as potentially positive in Screening mandate further confirmation.

If a sample yields a potential positive outcome during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from the hair at a notably lower concentration compared to other techniques (like urine or oral fluid), underscoring why hair drug analysis is regarded as a challenging procedure.

Positive results from a screening are affirmed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All potential positives undergo necessary washing prior to confirmation. The complete laboratory workflow from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair credential and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair analysis can uncover drug use for up to 90 days, whereas urine tests have shorter time frames.
• Challenging to manipulate: Hair tests are difficult to deceive, enhancing result reliability.
• Offers historical insight: It charts a timeline of substance usage, not just recent activity.

Limitations:

• Inability to detect recent intake: Detection in hair requires approximately 5-7 days post-drug use.
• Expense: Hair tests usually incur higher costs compared to other testing methods.
• Result variability: Factors including hair color and individual growth patterns can affect metabolite concentrations in hair.

Note: Commonly referred to as "hair follicle tests", the analysis targets the hair strand, not 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.
