Hair Follicle Drug Testing - George, IA

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. It offers a comprehensive history of substance use by retaining biomarkers within the strands of hair as they grow. When taken near the scalp, hair offers a detection period of up to 3 months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A sample length of 1.5 inches, comprising approximately 200 hairs (comparable in size to a #2 pencil) closest to the scalp, provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG testing, additional requirements, and/or tests exceeding 10 panels, a 150mg sample is preferred. It is advisable to use a jeweler’s scale for weighing the specimen. If scalp hair is not available, a corresponding amount of body hair can be used instead. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key stages in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within the lab's system. This step ensures the sample's proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any required data entry not covered by an electronic chain of custody.

Screening provides a preliminary evaluation for substance abuse. Although Screening is a cost-efficient approach for excluding drug use in the majority of samples, any positive screen must undergo confirmation to be legally valid. Samples with a preliminary positive result from Screening require secondary confirmation.

Should a sample test positive during the Screening phase, additional hair is taken from the original sample and readied for Extraction. Drugs are extracted from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive Screening result is completed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results are cleaned before confirmation, as necessary. The entire lab process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, as opposed to urine tests which have a shorter detection period.
• Difficult to manipulate: Cheating a hair drug test is exceedingly difficult, thus the results are more reliable.
• Historical insight: It offers a trend of drug consumption over time, not merely recent use.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variations: Factors such as hair color and differences in individual hair growth can influence drug metabolite levels in hair.

Note: Though sometimes called "hair follicle tests", the analysis is performed on 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.
