Hair Follicle Drug Testing - Thomasville, NC

What it is, How it works

Hair testing is now regarded as a significant method for detecting drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug use by capturing biomarkers within the strands as it grows. When a sample is obtained near the scalp, hair testing offers upto a roughly three-month detection timeframe for alcohol and drug presence. Collecting hair is straightforward, somewhat resistant to tampering, and can be easily transported.

A 1.5-inch hair sample consisting of roughly 200 strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for analysis and verification. For EtG, add-ons, or screenings exceeding 10 panels, a specimen size of 150mg is advised. It is suggested to measure the sample using a jeweler's scale. If head hair can't be collected, a similar amount of body hair is acceptable. "Head hair" strictly refers to scalp hair; "body hair" includes all other types (facial, armpit, etc.).

Process Overview

There are four primary stages in the laboratory processing of drug test samples: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial handling of a specimen into the lab's system. This process includes the authentication of proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody setup.

Screening carries out a preliminary and rapid assessment for abuse of drugs. Although Screening economically filters drug usage from most specimens, a positive result requires verification for court validity. Samples indicating presumed positivity in Screening necessitate additional confirmation.

When samples show presumed positives at the Screening phase, more hair is prepared from the original specimen for the Extraction process. At this step, lower concentrations of drugs are derived from hair compared to other methods (e.g., urine or oral fluids), making hair screening exceptionally challenging.

Confirming any positive screening involves GC/MS, GC/MS/MS, or LC/MS/MS. Each presumed positive sample is cleaned before confirmation if necessary. The entire lab routine from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair specialization and certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing can reveal drug use over a span of up to 90 days, unlike urine tests which have a shorter detection range.
• Challenge to bypass: It is highly challenging to falsify a hair drug test, thereby ensuring more accurate results.
• Delivers past data: It can display a drug usage pattern over time, as opposed to only recent utilization.

Limitations:

• Incapable of identifying recent usage: Drugs generally need about 5-7 days to become evident in hair.
• Expense: Hair drug testing is often costlier compared to alternative drug testing techniques.
• Discrepancies in results: Attributes like hair color and personal hair growth differences can influence the concentration of drug indicators in hair.

Note: Often labeled as "hair follicle tests," the examination focuses on the hair strand and 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.
