Hair Follicle Drug Testing - Nice, CA

What it is, How it works

Hair analysis has become recognized as an effective instrument for identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by embedding biomarkers within the strands' fibers. When sampled near the scalp, hair can offer a detection span of up to roughly three months for drugs and alcohol. Hair collection is straightforward, hard to tamper with, and easily transported.

An ideal specimen for testing and validation comprises a 1.5-inch segment of about 200 hair strands (about the width of a #2 pencil) located nearest to the scalp, yielding 100mg of hair. For tests exceeding 10 panels, EtG additions, or extensive tests, 150mg of hair is advised. It's best to measure the specimen with a jeweler’s scale. In the absence of scalp hair, an equivalent portion of body hair may be used. References to head hair specifically mean scalp hair. Conversely, body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary procedures in processing a drug test result in a lab involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab’s system. This process ensures the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes additional data inputs absent from an electronic chain of custody.

Screening provides a preliminary rapid assessment for drug presence. While it's a cost-efficient method to dismiss drug usage in most samples, a positive screen necessitates confirmation for court acceptance. Any specimen showing a presumptive positive in Screening requires further confirmation.

If Screening shows a presumptive positive, additional hair from the initial sample is prepared for Extraction. This process extracts drugs from hair at much lower levels compared to other methods like urine or oral fluid, rendering hair drug screening a challenging methodology.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The lab process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests, which offer a shorter detection period.
• Challenge to deceive: It is highly challenging to deceive a hair drug test, thereby enhancing result accuracy.
• Historical insight: It offers a timeline of drug use over a duration, not just recent usage.

Limitations:

• Inability to detect recent usage: Drugs require around 5-7 days to appear in hair samples.
• Expense: Hair drug tests generally incur higher costs than alternative drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the analysis actually examines the hair strand instead of the follicle under 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.
