Hair Follicle Drug Testing - Peru, NY

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol use. Hair retains evidence of alcohol and drugs over a long period by capturing markers in the hair's growing fibers. By collecting hair near the scalp, a detection timeframe of up to about 3 months for drugs and alcohol can be achieved. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample size of 1.5 inches, comprising roughly 200 strands (about a #2 pencil's diameter) closest to the scalp, yields 100mg of hair, which is ideal for assessment and validation. For tests such as EtG, add-ons, and those exceeding 10 panels, a specimen weighing 150mg is preferable. It is advisable to weigh the hair on a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be gathered. Our references to head hair exclusively concern scalp hair. Meanwhile, body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The primary phases in processing a drug test in the lab encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the initial stage, entering a sample into the laboratory’s system. This phase ensures the correct sealing and shipping of the sample, assigns a LAN (Laboratory Accessioning Number) at random, and completes any required data input not managed by an electronic chain of custody system.

Screening serves as a preliminary rapid test for drug presence. Screening offers a cost-effective method to eliminate drug usage for most samples; however, a positive result requires confirmation for court acceptance. Samples with presumptive positive results from Screening proceed to subsequent verification.

In instances where Screening indicates a presumptive positive, more hair from the initial sample is subjected to Extraction. Here, drugs are separated from the hair in significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), demonstrating why hair drug testing is among the most challenging techniques to execute.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing if needed before confirmation. The entire laboratory method from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days past, unlike urine tests, which detect over shorter durations.
• Hard to tamper with: Cheating a hair drug test is exceedingly tough, enhancing result credibility.
• Yields historical insights: Provides patterns of drug consumption over time, beyond mere recent use.

Limitations:

• Incapable of recent use detection: Drugs typically become evident in hair within 5-7 days.
• Expense: Hair drug tests usually incur higher costs compared to other methods.
• Result variability: Dye color differences and individual hair growth rates can alter drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests," this test evaluates the hair strand rather than 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.
