Hair Follicle Drug Testing - Fox Island, WA

What it is, How it works

The use of hair testing is regarded as an effective means for identifying drug and alcohol consumption. The fibers of growing hair strands can trap biomarkers, thus providing a prolonged history of alcohol and drug consumption. When collected near the scalp, hair can offer a detection period of up to about three months for both alcohol and drugs. Hair sampling is straightforward, hard to alter, and convenient to transport.

A sample of 1.5 inches consisting of roughly 200 hair strands (equivalent to a #2 pencil’s thickness) closest to the scalp yields 100mg of hair, which is the preferred quantity for both screening and confirmation. For tests that include EtG, add-ons, and/or exceed 10 panels, a specimen of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair may be collected. Here, head hair denotes specifically scalp hair. Body hair includes all other hair types (such as facial and axillary).

Process Overview

The drug test result processing in the lab involves four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage of incorporating a sample into a laboratory system. It comprises verifying the integrity and proper shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entries not covered by an electronic chain of custody system.

The Screening stage performs an expedited check for drugs of abuse. Although Screening is a cost-efficient method to dismiss drug presence in most samples, a positive result must be confirmed for legal admissibility. Samples with presumptive positive results in Screening need further confirmation.

If the Screening stage results in a presumptive positive, additional hair is extracted from the original specimen and prepared for Extraction. During Extraction, drugs are retrieved from the hair at much lower concentrations compared to other methods (like urine or oral fluids), highlighting the complexity of hair drug testing.

A confirmed positive result from Screening is verified using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptively positive samples undergo washing as required. The complete lab process, ranging from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can detect drug usage for up to 90 days, versus the shorter window offered by urine tests.
• Cheating difficulty: It’s quite challenging to falsify a hair drug test, ensuring more dependable results.
• Historical insight: The test offers a usage pattern over time, not limited to recent consumption.

Limitations:

• Recent use is undetectable: Drugs take about 5-7 days to show up in hair.
• Higher cost: Hair drug tests tend to cost more than other testing methods.
• Result variations: Factors like hair color and individual hair growth rates might influence drug metabolite concentration in hair.

Note: Despite being commonly called "hair follicle tests", the analysis is performed on the hair strand rather than 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. 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.
