Hair Follicle Drug Testing - Horse Pasture, VA

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair preserves a long-term record of alcohol and drugs by embedding biomarkers within the strands of the growing hair. Collected near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and drugs. It is easy to collect, somewhat resistant to tampering, and straightforward to transport.

A 1.5-inch segment of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, the preferred quantity for both screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for weighing is recommended. If scalp hair is not available, an equivalent quantity of body hair can be obtained. Reference to head hair pertains solely to scalp hair. Body hair denotes all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial sample entry into a lab's system. This process ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody.

Screening is an initial rapid assessment for drugs of abuse. While it serves as a cost-effective method to rule out drug use for most samples, a positive screening result must be confirmed for court admissibility. Samples that are presumptively positive in Screening require secondary confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (like urine or oral fluid), making hair drug screening particularly challenging to execute.

Confirmation of any positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are washed as needed before confirmation. The entire lab processing cycle from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and in accordance with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests with a shorter detection span.
• Challenging to deceive: Cheating a hair drug test is very difficult, leading to more precise results.
• Delivers historic data: It can show a trend of drug use over time, instead of just recent use.

Limitations:

• Cannot identify recent use: It takes around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are typically more costly than other drug testing methods.
• Result variations: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

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