Hair Follicle Drug Testing - White City, OR

What it is, How it works

Hair analysis has gained recognition as an effective means for uncovering drug and alcohol usage. Hair captures a prolonged history of substances by embedding biomarkers within the fibers of the growing hair. Collected near the scalp, it can offer a detection window of roughly 3 months for both alcohol and drugs. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.

A 1.5-inch hair specimen of about 200 strands (comparable to a #2 pencil) near the scalp yields 100mg, which is optimal for analysis and verification. For EtG, additional tests, or tests over 10 panels, 150mg is suggested. Utilizing a jeweler’s scale to weigh the sample is advisable. If scalp hair isn’t available, a similar amount of body hair can suffice. "Head hair" specifically denotes scalp hair, while "body hair" includes all other types like facial or axillary hair.

Procedure Overview

The key stages in the laboratory handling of a drug testing sample include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about the preliminary processing of a specimen into a lab’s system. This step ensures that the sample was suitably sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing data entry not captured by an electronic custody tracking system.

Screening offers a swift preliminary check for drug presence. Although Screening is a cost-efficient method to eliminate drug presence in most samples, any positive screen must be validated to be legally admissible. Samples that test presumptively positive in Screening need subsequent confirmation.

Should a sample appear presumptively positive in Screening, additional hair is extracted from the initial sample for Extraction. This phase extracts drugs from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), thus making hair drug screening the most complex methodology.

Any positive result during Screening is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation, as required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 standards accreditation.

Benefits of hair drug analysis:

• Prolonged detection period: Hair drug analysis can reveal drug use for up to 90 days, while urine analyses have a shorter detection span.
• Resistant to deceit: Altering a hair drug test is quite challenging, ensuring more reliable outcomes.
• Supplies historical insight: It can indicate drug use patterns over time, beyond just recent consumption.

Drawbacks:

• Lacks recent detection: Approximately 5-7 days are needed for drugs to be evident in hair.
• Expense: Hair drug analysis typically costs more than alternative testing methods.
• Result variations: Differences like hair color and individual hair growth rates can influence the drug metabolite concentration in hair.

Note: Often called "hair follicle tests", the analysis actually examines the hair strand, 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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
