Hair Follicle Drug Testing - Rouse, CA

What it is, How it works

Utilizing hair tests has emerged as an effective method for identifying substance and alcohol consumption. Hair encapsulates a prolonged record of alcohol and drug presence by trapping specific markers in the growing hair's structure. When extracted close to the scalp, hair can offer a detection timeframe of around three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches and consisting of roughly 200 hairs (akin to the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the preferred sample size for both screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, it's recommended to have 150mg of the sample. Using a jeweler’s scale is suggested for accurately measuring the specimen. If scalp hair cannot be obtained, the equivalent quantity of body hair is acceptable. By 'head hair', we exclusively mean scalp hair, while 'body hair' pertains to other hair types such as facial or underarm hair.

Process Overview

The primary stages involved in the laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into a lab's system. This stage involves ensuring that the sample is securely sealed and properly delivered, assigning it a random Laboratory Accessioning Number (LAN), and performing any additional data entry not covered by an electronic custody transfer system.

Screening entails a preliminary evaluation for substance abuse. Although Screening is an economical means to eliminate drug use in most samples, any positive results from Screening must be verified to be legally binding. Presumpively positive samples from Screening require further confirmation.

Should a sample be positive in the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other procedures (like urine or oral fluids), making hair drug testing the most challenging method to conduct.

Verification of any positive Screening outcome occurs through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples undergo washing as required before confirmation. The whole lab process, from Accessioning to Confirmation, is observed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use up to 90 days post-consumption, unlike urine tests, which have a shorter detection span.
• Hard to manipulate: It is nearly impossible to deceive a hair drug test, resulting in more reliable outcomes.
• Offers historical insight: It reveals a pattern of drug usage over a timeline, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs become identifiable in hair after about 5-7 days.
• Expense: Typically, hair drug tests are pricier than other drug testing techniques.
• Result variability: Hair color and personal differences in hair growth can influence the drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests", the examination targets the hair strand, 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.
