Hair Follicle Drug Testing - Gibson, WI

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drugs by embedding biomarkers within the strands' fibers. When sampled near the scalp, hair can reveal drug and alcohol presence for up to about three months. It is easy to collect, challenging to tamper with, and convenient for shipping.

A 1.5-inch hair sample roughly equivalent to 200 strands (comparable in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for both testing and validation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. We advise using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, an equivalent amount of body hair can be used. References to head hair specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result features four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab's system. This stage ensures the sample's seal and shipment accuracy, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not supplied by an electronic chain-of-custody system.

Screening is a preliminary, swift evaluation for drugs of abuse. Although Screening offers a cost-effective approach to ruling out drug usage across most samples, a positive result must be validated to hold up in court. Any samples showing a presumptive positive in Screening require secondary confirmation.

If a presumptive positive arises during the Screening phase, additional hair is extracted from the initial sample for Extraction. At this stage, drugs are extracted from hair in significantly lower concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to execute.

The Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples undergo a washing process prior to confirmation as necessary. The entire procedure from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and accredited to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for as long as 90 days, contrasting with urine tests, which feature a shorter detection window.
• Difficulty to cheat: Cheating on a hair drug test is exceedingly difficult, thus the results are more reliable.
• Provides historical data: It can demonstrate a timeline of drug use over an extended period, not just recent usage.

Limitations:

• Cannot detect recent use: Drugs require approximately 5-7 days to be detectable in hair.
• Cost: Generally, hair drug tests are pricier than alternative drug testing methods.
• Variations in results: Variables such as hair color and individual hair growth inconsistencies can influence the drug metabolites' concentration in the hair.

Note: Although often called "hair follicle tests", the test actually examines the hair strand and not 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.
