Hair Follicle Drug Testing - Hardwick, MN

What it is, How it works

Hair screening has emerged as an effective instrument for identifying alcohol and drug use. Hair retains a prolonged history of substances by embedding biomarkers within the fibers of the developing hair strand. When procured near the scalp, hair can offer a detection window of up to roughly 3 months for alcohol and other substances. Hair is straightforward to collect, relatively hard to tamper with, and effortless to transport.

A 1.5-inch segment comprising around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, the preferred sample for analysis and verification. For EtG, additional tests, and/or analyses exceeding 10 panels, a specimen weight of 150mg is advised. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not obtainable, an equivalent quantity of body hair might be collected. In reference to head hair, it pertains solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome encompasses four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the preliminary incorporation of a sample into a laboratory’s database. This includes checking the sample's proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and concluding any surplus data entry not managed by an electronic chain of custody system.

Screening entails an initial rapid examination for abusive substances. Although Screening is an economical means to dismiss drug consumption in most samples, a positive screening necessitates confirmation to be valid in legal contexts. Samples that are presumptively affirmative in Screening necessitate additional confirmation.

Should a sample be preliminarily positive in the Screening stage, supplementary hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at significantly diminished concentrations compared to other methodologies (e.g., urine or oral fluid), rendering hair drug screening the most challenging procedure to execute.

Confirmation of any positive screening outcome transpires through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug use up to 90 days, unlike urine tests that offer a briefer detection timeframe.
• Challenging to falsify: Cheating a hair drug test is exceedingly tough, rendering the outcomes more reliable.
• Yields historical information: It can supply a timeline of drug consumption over time, rather than merely recent activity.

Limitations:

• Incapable of identifying recent use: It necessitates about 5-7 days for substances to become detectable in hair.
• Expensiveness: Hair drug tests are generally costlier than other drug testing options.
• Result inconsistencies: Variables such as hair pigment and personal discrepancies in hair growth might influence the concentration of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the examination focuses on the hair strand 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.
