Hair Follicle Drug Testing - Del Rey, CA

What it is, How it works

Hair testing is increasingly recognized as a formidable resource for identifying the use of alcohol and drugs. Hair captures biomarkers in its fiber strands, offering a record of substance use over an extended period. When gathered near the scalp, this method can detect alcohol and drugs for up to about three months. Collection is straightforward, tampering is challenging, and shipping is uncomplicated.

A 1.5-inch section consisting of roughly 200 hair strands (approximately equivalent to a #2 pencil's size) near the scalp provides 100mg, the optimal sample size for testing. For EtG, add-ons, and/or tests exceeding ten panels, 150mg is advised. We suggest using a jeweler's scale for accuracy. If scalp hair is not present, an equivalent quantity of body hair can be substituted. Our reference to head hair specifically means scalp hair, excluding other hair types like facial or axillary hair.

Process Overview

The comprehensive lab processing framework for a drug test result comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is preliminarily processed into the lab's system. This phase ensures the sample's seal and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entries missing from an electronic chain of custody.

Screening provides an initial assessment for drugs of abuse. While it's an economical means for excluding drug use in most samples, a positive screen requires confirmation for legal acceptance. Samples with positive indications during Screening necessitate further verification.

If the Screening indicates a presumptive positive, additional hair is taken from the initial sample for Extraction preparation. This stage involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), marking it as the most intricate drug screening method.

Positive screening results undergo Confirmation using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptive positive are washed before confirmation as necessary. From Accessioning to Confirmation, the process adheres to the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests identify drug use up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Cheating deterrent: Cheating a hair drug test is exceptionally challenging, thus enhancing result reliability.
• Insightful historical data: It tracks a drug usage pattern over time, unlike identifying only recent use.

Limitations:

• Cannot identify recent use: Detectability in hair occurs roughly after 5-7 days of drug use.
• Expense: Hair drug tests are typically costlier compared to other methods.
• Result variability: Factors like hair color and growth variations can influence drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests," the test actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing triumphs over urine tests in Del Rey, CA, mainly due to enhanced detection capability and reliability. Unlike traditional methods, hair follicle tests capture a detailed picture of substance use.

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.
