Hair Follicle Drug Testing - Fieldale, VA

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the strands of growing hair. When obtained near the scalp, hair can offer approximately a 90-day detection window for alcohol and other substances. The collection process is straightforward, somewhat resistant to tampering, and easily transportable.

A 1.5-inch sample consisting of about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, 150mg is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair may be utilized. "Head hair" pertains exclusively to scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for handling a drug test outcome comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into the laboratory system. This phase includes validating that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing additional data input not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen requires validation for court admissibility. Any samples yielding a presumptive positive during Screening mandate secondary confirmation.

If a sample appears positive during the Screening phase, more hair is retrieved from the primary specimen for the Extraction phase. During this phase, substances are extracted from hair at much lower concentrations than other methods (such as urine or oral fluid), which makes hair drug screening among the most challenging methodologies to execute.

Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are subject to washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments reveal drug use up to 90 days, unlike urine tests with shorter detection durations.
• Difficulty in tampering: Cheating a hair drug test is exceedingly hard, enhancing result accuracy.
• Offers historical insights: Shows a pattern of drug use over time, not merely recent consumption.

Limitations:

• Inability to recognize recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variations: Factors like hair color and personal hair growth differences can impact drug metabolite concentration in the hair.

Note: Commonly termed "hair follicle tests", the assessment evaluates the hair strand, 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. 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.
