Hair Follicle Drug Testing - Afton, CA

What it is, How it works

Hair testing is now perceived as an effective method for identifying drug and alcohol consumption. Hair captures a long-duration record of alcohol and drugs by embedding biomarkers within the growing hair strand's fibers. When acquired near the scalp, hair can offer up to an approximate 3-month detection span for alcohol and drugs. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional analyses, and/or examinations beyond 10 panels, 150mg of the sample are advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is absent, a comparable volume of body hair can be collected. In our references to head hair, we exclusively mean scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

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

Accessioning consists of the initial sample processing into a lab's system. This step verifies the proper sealing and shipping of the sample, assigns a distinct LAN (Laboratory Accessioning Number), and fills any additional data entry gaps not covered by an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. Although Screening serves as a cost-efficient method to eliminate drug usage in most samples, a positive screen requires confirmation to be admissible in legal proceedings. Any samples with presumptive positive results during Screening necessitate a secondary confirmation.

If a sample yields a presumptive positive outcome in Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than those detected through other methodologies (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

The Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing as required before confirmation. Every part of the laboratory process, from Accessioning to Confirmation, follows a thorough review under the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can detect drug use for up to 90 days, as opposed to urine tests with a shorter detection span.
• Low susceptibility to tampering: The difficulty in altering a hair drug test makes the results more reliable.
• Offers usage history: It can reveal a drug use trend over an extended period, rather than just recent consumption.

Limitations:

• Inability to identify recent use: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although commonly termed as "hair follicle tests," the analysis itself examines 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.
