Hair Follicle Drug Testing - South Antelope Valley, CA

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug usage by capturing biomarkers within the strands of growing hair. By collecting hair near the scalp, it provides about a 3-month detection window for substances like alcohol and drugs. Hair is straightforward to gather, relatively challenging to tamper with, and convenient to transport.

A hair sample of 1.5 inches, consisting of roughly 200 strands (comparable to the width of a #2 pencil) and taken closest to the scalp, yields 100mg of hair, which is optimal for screening and verifying results. For EtG, additional tests, and/or examinations beyond 10 panels, a sample of 150mg is advised. We suggest utilizing a jeweler’s scale for measuring the specimen. If scalp hair is not accessible, a comparable measure of body hair can be collected. When we mention head hair, we specifically refer to scalp hair. Body hair encompasses all other hair types (including facial and axillary).

Process Overview

The laboratory procedure for processing a drug test outcome involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen into a laboratory's system. This step includes checking that the sample was sealed and sent appropriately, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not available through an electronic chain of custody system.

Screening offers an initial rapid evaluation for illicit drugs. While Screening is an economical method to exclude drug use in most samples, a positive screen must be verified for court acceptance. Samples with a presumptive positive in Screening necessitate additional confirmation.

Should a specimen show a presumptive positive during the Screening phase, more hair is removed from the initial sample for Extraction preparation. During this phase, drugs are extracted from hair at substantially lower concentrations than in alternative methods (such as urine or oral fluid), thus making hair drug screening the most complex method to execute.

Verification of any positive screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS techniques. All presumptively positive specimens undergo a washing process before confirmation if necessary. The comprehensive laboratory procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair directive and the ISO / IEC 17025 accreditation norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a reduced detection span.
• Difficult to falsify: Cheating a hair drug test is extremely hard, resulting in more accurate findings.
• Tracks historical trends: It shows a pattern of drug usage over time, not merely recent use.

Limitations:

• Unable to identify recent use: It takes around 5-7 days before drugs can be detected in hair.
• Expense: Hair drug tests are typically costlier than other testing methods.
• Result variability: Elements such as hair color and individual hair growth variations can impact the concentration of drug metabolites in hair.

Note: Commonly termed as "hair follicle tests", the test actually examines the hair strand rather than the hair 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.
