Hair Follicle Drug Testing - Tuxedo, NC

What it is, How it works

Hair testing has gained recognition as a potent means for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug usage by securing biomarkers within the fibers of the growing hair strand. When obtained near the scalp, hair can offer up to roughly a 3-month detection timeframe for alcohol and other drugs. Hair is easy to collect, somewhat challenging to tamper with, and convenient to transport.

A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the preferred sample for analysis and confirmation. For EtG, add-ons, and/or analyses exceeding 10 panels, 150mg of the sample is suggested. We advise measuring the sample on a jeweler’s scale. If scalp hair is inaccessible, an equal quantity of body hair can be collected. Referring to head hair pertains only to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four principal steps in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary handling of a sample into a laboratory’s system. This process verifies that the sample was securely sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not encompassed in an electronic chain of custody system.

Screening consists of an initial rapid assessment for drugs of abuse. Though Screening is a cost-effective avenue to exclude drug usage in most samples, a positive screen must be confirmed for courtroom admissibility. Samples that return a presumptive positive during Screening need secondary validation.

If a sample shows a presumptive positive result in the Screening phase, additional hair is retrieved from the initial sample and prepared for Extraction. During this stage, drugs are isolated from hair at significantly lower concentrations than through other methods (e.g., urine or oral fluid), which accounts for the complexity of hair drug testing.

Confirming any positive screen involves GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if needed. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair notation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can unveil drug use for up to 90 days, unlike urine tests which have a more limited detection timeframe.
• Difficulty to cheat: Hair drug tests are quite resistant to cheating, rendering the results more trustworthy.
• Provides historical data: Offers a timeline of drug use patterns over time, not solely recent use.

Limitations:

• Cannot detect recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Cost: Hair drug tests often incur higher costs than other testing methods.
• Variations in results: Variables like hair color and individual hair growth rates can alter the concentration of drug metabolites within the hair.

Note: Despite being commonly dubbed as "hair follicle tests", the analysis targets the hair strand, excluding the hair 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.
