Hair Follicle Drug Testing - Cima, CA

What it is, How it works

Hair testing has emerged as an effective method to detect drug and alcohol usage. Hair retains a long-term record of alcohol and other drugs by entrapping biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can provide an approximately 3-month detection timeframe for alcohol and other drugs. Hair collection is straightforward, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 strands of hair (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred sample size for screening and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg of the sample is suggested. We advise measuring the specimen using a jeweler’s scale. If scalp hair is unavailable, a similar volume of body hair can be collected. When we mention head hair, we mean only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a lab's system. This comprises confirming that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not provided by an electronic chain of custody system.

Screening subjects a sample to an initial fast check for drugs of abuse. While Screening is a cost-efficient means to eliminate drug usage in most samples, a positive screen requires confirmation for legal admissibility. Any samples deemed presumptively positive in Screening necessitate secondary confirmation.

If a sample is categorized as presumptively positive during the Screening stage, additional hair is extracted from the initial sample and prepped for Extraction. In this stage, drugs are isolated from hair in much lower concentrations than in other methods (such as urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation if needed. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests which have a more limited detection window.
• Difficulty to cheat: Cheating on a hair drug test is exceptionally difficult, ensuring more accurate results.
• Provides historical data: It can reflect a pattern of drug use over time, not merely recent usage.

Limitations:

• Cannot detect recent use: Drugs require about 5-7 days to become detectable in hair.
• Cost: Hair drug tests tend to be more costly than other drug testing methods.
• Variations in results: Elements such as hair color and personal differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although commonly referred to as "hair follicle tests", this test actually analyzes the hair strand 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.
