Hair Follicle Drug Testing - Alpaugh, CA

What it is, How it works

Hair testing is increasingly valued as an effective means for identifying drug and alcohol usage. Hair offers a prolonged record of drug and alcohol consumption by embedding biomarkers within the strands of growing hair. When obtained near the scalp, hair can present a detection period of up to around three months for substances. It is uncomplicated to collect, somewhat resistant to tampering, and straightforward to transport.

Gathering a 1.5-inch cut of roughly 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal quantity for analysis and verification. For EtG, additional tests, and/or evaluations exceeding 10 panels, a 150mg sample is advisable. Measuring the specimen on a jeweler's scale is suggested. If scalp hair is unavailable, an equal amount from body hair may be gathered. References to head hair mean only scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning handles the initial integration of a sample into a lab’s system, checking that it was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing supplementary data entry absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for drug substances. Although Screening economically dismisses drug usage in most samples, any positive results require confirmation for legal admissibility. Presumptively positive samples from Screening necessitate secondary verification.

If a Screening is presumptively positive, additional hair is pulled from the original sample for Extraction, where drugs are isolated at much lesser concentrations than through other methods (e.g., urine or oral fluid), marking hair drug screening as one of the most challenging methodologies.

Confirmation of any positive screening results is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned as needed before confirmation. The entire process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests reveal substance use up to 90 days, whereas urine tests have shorter detection spans.
• Cheating is challenging: The difficulty in falsifying a hair drug test improves accuracy.
• Delivers historical insight: It reveals patterns of drug use over time, not solely recent consumption.

Limitations:

• Inability to detect recent consumption: It takes approximately 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are usually costlier than alternative drug testing techniques.
• Result variability: Variables like hair color and personal hair growth differences can influence drug metabolite levels within hair.

Note: Commonly termed "hair follicle tests", these actually examine 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.

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.
