Hair Follicle Drug Testing - Naytahwaush, MN

What it is, How it works

Hair testing is increasingly recognized as an effective resource for identifying drug and alcohol consumption. The fibers of the growing hair strand capture biomarkers, providing a prolonged timeline for substance detection. Hair, especially when collected near the scalp, offers an approximately three-month detection period for both alcohol and drugs. Its collection is straightforward, challenging to tamper with, and convenient to ship.

A 1.5-inch sample consisting of roughly 200 hair strands (approximating the thickness of a #2 pencil) cut close to the scalp yields 100mg of hair, which is ideal for both screening and confirmation tests. For EtG, additional tests, or panels exceeding 10, a specimen size of 150mg is advised. To ensure accuracy, we suggest weighing the sample using a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be collected. The term head hair refers specifically to scalp hair, while body hair pertains to all other types (such as facial and axillary hair).

Process Overview

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

Accessioning is the initial step where a sample is entered into the laboratory’s system. This step includes confirming the sample’s secure sealing and proper shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any manual data entry not captured by an electronic chain of custody system.

Screening entails a rapid preliminary test for the presence of drugs. Though cost-effective for ruling out drug use in most samples, a positive screen must be confirmed to ensure it is admissible in legal proceedings. Samples that yield a presumptive positive result during Screening require further confirmation through a secondary process.

If a sample tests presumptively positive during Screening, additional hair from the original specimen is sourced and prepared for Extraction. In this phase, drugs are extracted from hair at concentrations far lower than in other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screening.

Any positive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples identified as presumptively positive are washed before Confirmation as necessary. From Accessioning to Confirmation, the entire laboratory process undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Challenging to manipulate: The difficulty in cheating with a hair drug test enhances result accuracy.
• Supplies historical insight: It provides a drug use pattern over time, rather than only recent usage data.

Limitations:

• Unable to detect recent consumption: Drugs become detectable in hair only after about 5-7 days.
• Expense: Generally more expensive when compared to other drug testing methods.
• Result variability: Factors like hair color and growth variations among individuals can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed as "hair follicle tests", the test analyzes 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. 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.
