Hair Follicle Drug Testing - Saint Clair, MN

What it is, How it works

Hair testing has emerged as an influential mechanism for identifying drug and alcohol consumption. Hair secures a prolonged history of alcohol and drug exposure by embedding biomarkers within the growing hair fibers. When collected near the scalp, hair is capable of offering a detection timeframe of up to roughly 3 months for both alcohol and drug presence. Collecting hair is straightforward, challenging to tamper with, and convenient for shipment.

A 1.5-inch segment comprising around 200 hair strands (approximately the diameter of a #2 pencil) from nearest to the scalp yields 100mg of hair, the optimal sample size for screening and validation. For EtG, extensions, and/or evaluations exceeding 10 panels, a 150mg sample is suggested. We advise utilizing a jeweler's scale to weigh the specimen. Should scalp hair be inaccessible, an equivalent volume of body hair may be harvested. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Summary

The laboratory processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a sample into a laboratory’s framework. This process involves confirming the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any further data entry not supplied by an electronic chain of custody system.

Screening involves an initial rapid assessment for recreational drugs. Although Screening provides a cost-efficient method to exclude drug use in most samples, a positive screen mandates confirmation for legal admissibility. All samples that test presumptively positive during Screening necessitate a successive confirmation.

Should a sample test presumptively positive in Screening, additional hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are isolated from hair at markedly lower concentrations than in other methodologies (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.

The validation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as required. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug use for as long as 90 days, unlike urine tests which feature a more limited detection timeframe.
• Challenges in falsification: Cheating a hair drug test is exceedingly difficult, enhancing the accuracy of the results.
• Historical utilization data: It offers a record of drug use over time rather than merely recent usage.

Drawbacks:

• Incapable of detecting current use: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair drug tests are typically pricier than alternative drug evaluation techniques.
• Result variability: Aspects such as hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Though frequently termed "hair follicle tests," the analysis targets the hair shaft rather than 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.
