Hair Follicle Drug Testing - Wheeler, IL

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the hair strand as it grows, hair offers a prolonged record of alcohol and drug usage. When gathered near the scalp, hair can present a detection window extending roughly 3 months for alcohol and other drugs. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment, consisting of around 200 strands (roughly the size of a #2 pencil) closest to the scalp, will produce 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest weighing the hair on a jeweler’s scale. If scalp hair is unavailable, a similar amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair pertains to any other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a laboratory’s system. This process includes verifying the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.

Screening involves an initial rapid test for drugs of abuse. While Screening provides a cost-effective method to rule out drug usage for the majority of samples, a positive result requires confirmation to be legally admissible. All samples with a presumptively positive Screening result must undergo a follow-up Confirmation.

Upon a presumptive positive result in the Screening phase, additional hair is taken from the original specimen and prepped for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), which is reason for hair drug screening's high complexity.

Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are pre-washed before Confirmation if necessary. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage for up to 90 days, as opposed to urine tests which have a shorter detection period.
• Difficult to deceive: Cheating a hair drug test is very challenging, rendering the outcomes more reliable.
• Offers historical data: It supplies a pattern of drug use over an extended period, not just recent use.

Limitations:

• Cannot detect recent use: It takes approximately 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Result variations: Variables such as hair color and individual discrepancies in hair growth can impact the drug metabolite concentration in the hair.

Note: Despite being frequently termed "hair follicle tests", the test itself evaluates the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Wheeler, IL, hair follicle testing stands out for its exceptional detection capabilities compared to urine tests.

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.
