Hair Follicle Drug Testing - Walthill, NE

What it is, How it works

Hair analysis has become recognized as a robust method for the identification of drug and alcohol consumption. Hair captures a long-duration record of alcohol and drug intake by embedding biomarkers in the structure of the growing hair strand. If collected near the scalp, hair can offer approximately a 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easily transportable.

An approximately 1.5-inch segment of about 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, the perfect amount for screening and validation. For EtG, additional testing, and/or tests over 10 panels, 150mg of the specimen is advised. We propose verifying the specimen's weight on a jeweler’s scale. If scalp hair is inaccessible, a similar quantity of body hair might be gathered. By head hair, we specifically mean scalp hair only. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The key phases in the laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample into a laboratory’s framework. This process includes checking that the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and finalizing any further data entry absent in an electronic chain of custody system.

Screening involves an initial rapid assessment for drugs of abuse. While Screening offers a cost-efficient approach to exclude drug use in the majority of samples, a positive result must be verified to be permissible in court. Samples showing presumptive positivity in Screening necessitate additional verification.

In cases where a sample is presumptively positive during the Screening phase, further hair is pulled from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at markedly lower concentrations than other techniques (ex. urine or oral fluid), which is why hair drug screening remains the most complex technique to conduct.

Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo cleansing before verification as required. The entire laboratory sequence from Accessioning to Confirmation is critically assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests are capable of detecting drug usage for a period of up to 90 days, unlike urine tests which have a shorter detection span.
• Challenging to manipulate: Cheating a hair drug test is extremely hard, thus making the outcomes more dependable.
• Delivers historical data: Such tests can demonstrate a pattern of drug usage over an interval, rather than just recent use.

Limitations:

• Incapable of detecting recent use: A period of approximately 5-7 days is needed for drugs to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs compared to other drug screening options.
• Inconsistencies in results: Elements such as hair color and individual differences in hair growth can influence the drug metabolite concentration in hair.

Note: Though frequently referred to as "hair follicle tests", the actual test examines the hair strand, not the follicle located 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.
