Hair Follicle Drug Testing - Taholah, WA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive history of alcohol and drug use by capturing biomarkers within the strands as they grow. Collected near the scalp, hair can deliver nearly a 3-month detection period for alcohol and drugs. Hair is easy to collect, hard to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (similar to the width of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample for analysis and verification. For EtG, add-ons, or tests beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler's scale to measure the specimen weight. If scalp hair is missing, a comparable quantity of body hair can be taken. When discussing head hair, we mean scalp hair specifically. Body hair denotes all other hair types (facial, axillary, and so on).

Process Overview

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

Accessioning entails the initial handling of a sample into a laboratory’s system. It includes checking that the sample was correctly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any further data entry not available via an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. Though Screening is a cost-efficient method to rule out drug use in most samples, a positive result must be confirmed for legal acceptance. Samples that are provisionally positive require secondary confirmation.

If a sample is provisionally positive at the Screening phase, more hair is sourced from the original sample and readied for Extraction. During this phase, drugs are drawn from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), explaining why hair drug analysis is the most challenging methodology to execute.

Confirmation of any positive screening outcome is performed with GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All provisional positive samples are cleansed before confirmation, as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection timeframe: Hair drug tests can uncover drug use for up to 90 days, compared to urine tests, which have a shorter detection interval.
• Hard to falsify: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Historical insights: It provides a trend of drug usage over a time span, not merely recent activity.

Limitations:

• Cannot identify recent usage: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Result variability: Factors such as hair color and individual growth rates can influence the drug metabolite concentration in hair.

Note: Although often styled as "hair follicle tests", the evaluation examines the hair strand rather than 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.
