Hair Follicle Drug Testing - Weaverville, CA

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a comprehensive record of substance use by embedding biomarkers within the shaft of the growing hair. When samples are collected near the scalp, they can offer approximately a 3-month detection window for substances like alcohol and other drugs. Hair sampling is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is the ideal amount for screening and confirmation purposes. For EtG, additional substances, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. Utilizing a jeweler’s scale for weighing the specimen is recommended. In the absence of scalp hair, an equivalent amount of body hair can be used. When discussing head hair, it refers exclusively to scalp hair. Conversely, body hair pertains to all other types (facial, axillary, etc.).

Process Overview

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

During Accessioning, the sample undergoes initial integration into a laboratory’s system. This process entails verifying the correct sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.

Screening consists of an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient strategy to exclude drug usage for most samples, a positive screen necessitates confirmation for legal admissibility. Samples yielding a presumptive positive result in Screening must undergo further confirmation.

In scenarios where the Screening stage suggests a positive result, an additional portion of hair from the initial specimen is utilized for Extraction. During Extraction, drugs are removed from the hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to execute.

Confirmation for any positive screen results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of all presumptive positive samples is done before confirmation. The complete laboratory process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, unlike urine tests which have a briefer detection range.
• Resistant to manipulation: It is exceedingly hard to tamper with a hair drug test, thus enhancing result accuracy.
• Chronological consumption data: It delivers a timeline of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Generally, hair drug tests are pricier than other testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Although often referred to as "hair follicle tests", the evaluation is conducted on the hair strand itself, 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.
