Hair Follicle Drug Testing - La Paz Valley, AZ

What it is, How it works

Hair analysis is now viewed as an efficient method for identifying drug and alcohol consumption. By embedding biomarkers in the strands, hair gives a long-term record of these substances in the body. If collected near the scalp, hair can offer a detection timeframe of around three months for various substances. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.

A sample roughly 1.5 inches long, consisting of about 200 strands of hair (comparable in size to a #2 pencil) close to the scalp, will yield 100mg, which is perfect for both screening and confirmation. For EtG, extra tests, and those beyond 10 panels, a 150mg sample is suggested. We advocate measuring the sample using a jeweler’s scale. If head hair isn’t available, a similar quantity of body hair can be used. Head hair refers solely to hair from the scalp, whereas body hair encompasses all other types (such as facial and axillary hair).

Process Overview

There are four essential stages in the lab analysis of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where the lab incorporates a sample into their system. This step ensures the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic custody system.

Screening provides an initial quick assessment for drug abuse indicators. It’s a cost-efficient technique to exclude drug usage for most samples, although a positive result here must be confirmed to be court-admissible. Presumptive positives in this test need further confirmation.

For samples suggesting positivity at Screening, a portion of hair is taken from the original sample and set for Extraction. Drugs are extracted from hair at a much lower concentration in this stage compared to other methods (e.g., urine or oral fluids), making hair testing one of the most intricate practices.

Confirmation of any positive screen results is conducted via GC/MS, GC/MS/MS, or LC/MS/MS processes. All samples with a presumptive positive result undergo a wash before confirmation. The entire progression from Accessioning to Confirmation is subject to evaluation under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair tests can reveal drug use for a duration of up to 90 days, which is longer than the window for urine tests.
• Hard to manipulate: Cheating on a hair drug test is quite challenging, ensuring more reliable results.
• Historical insights: It can show a drug usage pattern over time, instead of just recent use.

Limitations:

• Cannot uncover recent drug use: It takes roughly 5-7 days for drugs to be measurable in hair.
• Expensive: Hair drug tests often cost more than other testing alternatives.
• Result variability: Factors such as hair color and personal hair growth rates can influence the level of drug metabolites in hair.

Note: Although these are referred to as "hair follicle tests", they're only concerned with the hair strands, not the follicles 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.
