Hair Follicle Drug Testing - Lewisetta, VA

What it is, How it works

Hair testing is now recognized as an effective method for detecting drug and alcohol consumption. Hair offers a long-term record of alcohol and drug use by embedding biomarkers within the fibers of the hair strand as it grows. When hair is collected near the scalp, it can reveal alcohol and drug usage for up to about three months. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A 1.5-inch hair sample consisting of approximately 200 strands (comparable in thickness to a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG enhancements or tests extending beyond 10 panels, a 150mg sample is advised. It's beneficial to weigh the sample using a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair can be used. In this context, head hair refers solely to scalp hair, whereas body hair encompasses all other hair categories (such as facial and axillary hair).

Process Overview

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

Accessioning involves incorporating a sample into the laboratory's system initially. This process includes verifying the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entry that an electronic chain of custody system hasn't covered.

Screening is a preliminary quick test for identifying drugs of abuse. While it's cost-effective for eliminating drug use in most samples, a positive screening result must be confirmed to be valid in legal settings. Samples with presumptive positive results in Screening require secondary confirmation.

If Screening yields a presumptive positive result, additional hair is extracted from the original sample and prepared for Extraction. During this step, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which accounts for why hair drug screening poses the most challenging methodology to conduct.

Confirmation for any positive screening outcomes is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo a wash before confirmation, as necessary. The comprehensive laboratory process from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and accreditation with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests that have a shorter detection period.
• Challenge to adulterate: It is notably difficult to tamper with a hair drug test, leading to more reliable results.
• Historical insights: It can depict a pattern of drug consumption over a duration, not merely the recent use.

Limitations:

• Incapable of detecting recent usage: It generally takes around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing tends to be costlier than other drug testing methods.
• Result variations: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although frequently termed as "hair follicle tests", the analysis actually examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lewisetta, VA, hair follicle testing offers advantages over standard urine tests. Hair tests are less likely to be manipulated and provide a longer detection window, often revealing drug use up to 90 days prior.

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.
