Hair Follicle Drug Testing - Azwell, WA

What it is, How it works

Hair analysis has emerged as a potent method for identifying use of drugs and alcohol. It offers a comprehensive history of substance consumption by encapsulating chemical markers within the hair's fibers as it grows. When gathered near the scalp, hair provides an approximate 3-month detection timeline for alcohol and other substances. It is easy to collect, tough to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands, about the girth of a #2 pencil, taken nearest to the scalp will yield 100mg of hair, the prime amount for testing and verification. For EtG tests, additional panels, or tests above 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not available, a comparable quantity of body hair can be used. The term head hair denotes only to scalp hair. Body hair encompasses other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step in the integration of a sample into a lab’s system. This involves checking the sample’s seal and shipment, assigning it a random LAN (Laboratory Accessioning Number), and entering any additional data not provided electronically.

Screening provides a preliminary check for substance abuse. Although it's a cost-efficient method to exclude drug use in most cases, a positive outcome from Screening must be verified for legal acceptability. Samples with a presumptive positive in Screening require further confirmation.

When a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample and readied for Extraction. During this step, drugs are removed from hair in much lower concentrations than other methods, such as urine or oral fluid, making it the most challenging method for drug screening.

Confirmation of any positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing before confirmation if needed. The complete process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have shorter detection capabilities.
• Challenging to falsify: It is significantly hard to falsify hair drug tests, enhancing result reliability.
• Gives historical insight: It can reveal a drug use pattern over time, not merely recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after consumption.
• Expense: Hair drug tests generally cost more than other testing options.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although frequently labeled as "hair follicle tests", the assessment actually evaluates the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
