Hair Follicle Drug Testing - Nottoway Court House, VA

What it is, How it works

Hair analysis has become recognized as an effective instrument for identifying alcohol and drug consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the strands as they grow. When sampled near the scalp, it can provide a detection window for substances lasting up to about three months. Collecting hair is straightforward, challenging to tamper with, and simple to send.

A sample of 1.5 inches, consisting of around 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp, will yield 100mg of hair, which is the preferred amount for evaluation and verification. For EtG, additional testing, or tests exceeding 10 panels, a specimen of 150mg is suggested. Using a jeweler’s scale to weigh the specimen is advisable. If scalp hair is absent, an equivalent quantity of body hair is a viable alternative. Referring to head hair indicates scalp hair exclusively. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The critical phases in the lab processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab's system. This step involves checking that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and performing any extra data input absent from an electronic chain of custody system.

Screening includes an initial rapid assessment for substance abuse. Although Screening offers a cost-effective method to exclude drug use for most samples, positive screens must be verified to stand in court. Presumptive positives from Screening necessitate a subsequent confirmation.

Upon receiving a presumptive positive during Screening, further hair is extracted from the initial sample for Extraction. At this phase, substances are extracted from hair at a significantly lower concentration compared to other methods (such as urine or oral fluids), making hair drug screening the most complex methodology to execute.

Verification of a positive screen is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a cleansing process before confirmation if necessary. The comprehensive lab procedure, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests which have a briefer detection interval.
• Hard to falsify: Cheating on a hair drug test is extremely difficult, enhancing result accuracy.
• Offers historical insight: It constitutes a record of drug use patterns over time, not just recent use.

Limitations:

• Incapable of identifying recent usage: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be pricier compared to alternative drug testing methods.
• Result variability: Attributes like hair color and natural differences in hair growth can influence drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests," the procedure examines the hair strand, not the follicle under 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. 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
