Hair Follicle Drug Testing - Sonoita, AZ

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair records a prolonged history of alcohol and drug use by capturing biomarkers within its strands during growth. When taken from near the scalp, hair offers up to a roughly 3-month detection period for alcohol and drugs. The collection of hair is easy, challenging to tamper with, and straightforward to transport.

A 1.5-inch sample amounting to around 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair isn't present, a comparable quantity of body hair may be obtained. By head hair, we mean only scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the initial processing of a sample into the lab’s system. This process ensures proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and performs any additional data entry beyond what an electronic chain of custody system provides.

Screening serves as a preliminary examination for substances of abuse. Though Screening is an economical means to identify drug use in most samples, a positive screen necessitates verification to be valid in legal settings. Any samples reading presumptively positive during Screening demand further confirmation.

For samples showing a presumptive positive during Screening, extra hair is taken from the initial sample and prepped for Extraction. Here, drugs are removed from hair at far lesser concentrations than found in other methods (such as urine or oral fluid), which makes hair drug screening the most complex method to execute.

Verification of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed prior to verification as needed. The comprehensive lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests reveal drug use up to 90 days back, unlike urine tests with shorter detection periods.
• Hard to falsify: Cheating on a hair drug test is notably hard, ensuring more reliable outcomes.
• Offers historical usage data: It illustrates a pattern of drug use over time, not merely recent use.

Limitations:

• Cannot uncover recent use: It requires around 5-7 days for drugs to be visible in hair.
• Expense: Hair drug tests typically cost more than alternative drug testing techniques.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the drug metabolite levels in hair.

Note: Despite the common term "hair follicle tests", the test evaluates the hair strand, 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.
