Hair Follicle Drug Testing - Whaleyville, VA

What it is, How it works

Hair assessments have been recognized as an effective means for identifying drug and alcohol use. Hair provides an extended-record history of alcohol and other substances by capturing biomarkers within the fibers of the growing hair strand. When obtained near the scalp, hair can offer up to an estimated 3-month detection period for alcohol and drugs. Hair is easy to collect, somewhat hard to tamper with, and simple to transport.

A 1.5-inch segment of about 200 hairs (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal sample for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's recommended to measure the sample using a jeweler’s scale. If head hair is not available, an equal quantity of body hair can be collected. When discussing head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The primary steps involved in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into a lab’s system. This incorporates confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening entails an initial brief examination for drugs of concern. Although Screening is an economical method to exclude drug use on most samples, a positive screen must be validated to be court-admissible. Any samples that indicate a presumptive positive in Screening require a second confirmation.

If a sample indicates a presumptive positive in the Screening phase, more hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are obtained from hair at a substantially lower concentration than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to undertake.

Every positive screening result undergoes confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as necessary. The entire laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can determine drug usage for up to 90 days, unlike urine tests that have a shorter detection duration.
• Complex to deceive: Cheating a hair drug test is quite challenging, ensuring more precise results.
• Offers historical insight: It offers a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Cannot identify recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more compared to other drug testing methods.
• Result variations: Elements such as hair color and individual differences in hair growth may impact the concentration of drug metabolites in the hair.

Note: Although commonly termed as "hair follicle tests", the procedure itself evaluates the hair strand, not the hair follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
