Hair Follicle Drug Testing - Shackelford, CA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. It captures a long-term record of substances by embedding biomarkers in the hair's fibers as it grows. When the hair is trimmed near the scalp, it offers up to a roughly three-month time frame for detecting alcohol and other drugs. Collecting hair is straightforward, hard to tamper with, and simple to transport.

A section of hair that is 1.5 inches long and contains about 200 strands (comparable in size to a #2 pencil) closest to the scalp will provide 100mg of hair, which is an optimal amount for evaluation and verification. For EtG, supplementary add-ons, or analyses over 10 panels, 150mg of the hair is advised. It is recommended to measure the sample using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent portion of body hair can be used. The term "head hair" specifically refers to hair from the scalp. "Body hair" encompasses all other hair types (facial, underarm, etc.).

Process Overview

The laboratory procedure for processing a drug test result includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample initially enters the laboratory system. This process involves confirming that the sample was appropriately sealed and delivered, generating a unique LAN (Laboratory Accessioning Number), and completing any additional information that might not have been included in an electronic chain of custody system.

Screening provides a preliminary overview for potential drugs of abuse. Although Screening is an economical method to eliminate drug usage in most samples, a positive finding requires confirmation for legal acceptance. All samples that indicate a positive result from Screening need further confirmation.

If a sample returns a presumptive positive from the Screening phase, additional hair is obtained from the original sample for the Extraction phase. In this stage, drugs are retrieved from the hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.

Any positive results from the preliminary screening are confirmed through the use of GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The full laboratory procedure from Accessioning through Confirmation is examined under the guidelines of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to three months, in contrast to urine tests with a more limited detection window.
• Hard to manipulate: It is quite challenging to compromise a hair drug test, thus enhancing the accuracy of the results.
• Offers historical perspective: The test can reveal a pattern of drug use over time, rather than focusing solely on recent usage.

Limitations:

• Unable to identify recent use: There is an approximate 5-7 day delay before drugs become detectable in hair.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can impact drug metabolite concentrations in the hair.

Note: Although often termed "hair follicle tests," the analysis is conducted on the hair strand rather than 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.
