Hair Follicle Drug Testing - Swatara, MN

What it is, How it works

Hair testing has increasingly been recognized as a significant approach to identify drug and alcohol consumption. Hair can capture a long-term record of alcohol and drugs by encasing biomarkers within the fibers of its growing strand. When gathered near the scalp, hair can provide an approximate 3-month detection period for alcohol and drugs. Hair is straightforward to collect, relatively resistant to tampering, and simple to transport.

A 1.5-inch strand of roughly 200 hairs (about the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-on tests, or those exceeding 10 panels, 150mg of the sample is advised. It's best to measure the specimen on a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be gathered. When mentioning head hair, it specifically denotes scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The core phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample's initial integration into a lab’s system, including verifying proper sample sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.

Screening provides a preliminary swift examination for drugs. Although Screening is cost-efficient for eliminating drug use in most samples, a positive screen must be confirmed to be court-admissible. Any samples that are potentially positive in Screening require additional confirmation.

If a sample is potentially positive during Screening, more hair from the initial sample is used and prepped for Extraction. Here, drugs are removed from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), which explains why hair drug screening is the toughest technique to execute.

Confirmation of any positive screening result is completed via GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples are washed before confirmation as needed. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests can detect drug use up to 90 days, unlike urine tests that have a shorter detection period.
• Challenging to cheat: It's notably hard to falsify a hair drug test, ensuring more precise results.
• Offers historical insight: It shows a drug usage pattern over time, not just recent consumption.

Limitations:

• Unable to detect recent usage: Drugs typically take 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Result variations: Hair color and personal differences in hair growth may impact drug metabolites' concentration within the hair.

Note: Commonly termed as "hair follicle tests", this test examines 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.
