Hair Follicle Drug Testing - Hacienda Heights, CA

What it is, How it works

The utilization of hair tests has emerged as an instrument of significance for detecting drug and alcohol consumption. Hair captures extended periods of substance history by preserving biomarkers within the strands' fibers. When sampled near the scalp, hair can indicate usage of substances over an estimated three-month span. Collecting hair is straightforward, somewhat challenging to tamper with, and convenient for transportation.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (equivalent to a #2 pencil), closest to the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is suggested. We advocate weighing the specimen on a jeweler’s scale. If scalp hair cannot be acquired, a similar quantity of body hair can be used. When mentioning head hair, we mean only scalp hair. Body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The primary four steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the introductory handling of a sample into the lab's framework. This step includes ensuring the sample was securely sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody system.

Screening offers a preliminary rapid assessment for substance misuse. While Screening provides a budget-friendly way to negate drug use in most samples, a positive finding requires confirmation to hold up in legal proceedings. Samples showing preliminarily positive results in Screening necessitate further confirmation.

Should a sample test presumptively positive in Screening, more hair is extracted from the initial batch and readied for Extraction. During this process, substances are retrieved from hair at concentrations far lower than in other methods (like urine or oral fluid), making hair drug screening the toughest protocol to administer.

Validation of any positive screening result occurs through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before verification as needed. The lab process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can trace drug usage for a span of up to 90 days, unlike urine assessments which offer shorter detection periods.
• Hard to falsify: A hair drug test is notably difficult to compromise, enhancing result accuracy.
• Yielding historical insight: It can display a timeline of drug consumption over a duration, beyond just recent usage.

Limitations:

• Inability to indicate recent usage: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair drug assessments tend to incur higher costs than alternative testing approaches.
• Result disparity: Drug metabolite concentrations in hair can be influenced by variables like hair color and personal hair growth differences.

Note: While colloquially known as "hair follicle tests", the analysis actually focuses on the hair strand itself 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.
