Hair Follicle Drug Testing - Walnut Grove, MN

What it is, How it works

Recognized as a vital instrument in uncovering drug and alcohol consumption, hair analysis provides an extended retrospective by capturing markers within the fibrous structure of growing hair strands. When taken near the scalp, hair offers a retrospective detection window of approximately three months for alcohol and drugs. The hair collection process is straightforward, challenging to tamper with, and simple to transport.

Collecting a 1.5-inch segment comprising about 200 strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is deemed optimal for analysis and verification. For EtG, additional assessments, and tests beyond ten panels, a 150mg sample is advisable. It's suggested to weigh the specimen using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair may be obtained. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other types of hair (such as facial or axillary).

Process Outline

The fundamental stages in laboratory drug test processing encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a specimen into a laboratory framework. This involves ensuring the sample was securely sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.

Screening serves as an initial rapid assay to check for illicit substances. While Screening is an economical method to dismiss drug usage in most samples, a positive screen necessitates confirmation to hold up in legal contexts. Any samples presumptively positive during Screening must undergo a secondary verification.

If a specimen shows presumptive positivity in Screening, more hair is derived from the original sample for Extraction, where drugs are isolated from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluids), underscoring the complexity of performing hair drug analysis.

Detailed Confirmation of any positive screening outcome is executed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo purification before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification alongside ISO / IEC 17025 accreditation standards.

Perks of hair drug screening:

• Extended detection period: Hair drug tests can identify drug use over a span up to 90 days, whereas urine tests provide a narrower detection margin.
• Difficult to manipulate: It's nearly impossible to falsify a hair drug test, enhancing result integrity.
• Reveals historical usage: It outlines a timeline of drug consumption, instead of merely recent activity.

Drawbacks:

• Incapable of spotting recent usage: Drugs typically become traceable in hair after about 5-7 days.
• Expense: Hair drug tests generally incur higher costs than alternate drug screening methods.
• Result variability: Aspects like hair pigmentation and personal hair growth variations can influence drug metabolite concentration in hair.

Note: The analysis frequently termed as "hair follicle tests" actually evaluates the hair strand itself and not the follicle residing 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.
