Hair Follicle Drug Testing - Central Valley, WA

What it is, How it works

Hair testing is regarded as a robust method for detecting drug and alcohol consumption. Such testing offers an extended history of substance use by encapsulating biomarkers within the growing hair's fibers. When obtained near the scalp, hair samples can demonstrate a detection period of up to roughly 3 months for substances. Hair collection is straightforward, hard to tamper with, and easily transported.

A 1.5-inch segment containing about 200 strands of hair (approximately the width of a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimal sample for both screening and confirmation processes. For EtG, additional tests, and/or analyses beyond 10 panels, 150mg of the sample is advised. It is beneficial to gauge the sample using a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair might be used. References to head hair pertain exclusively to scalp hair. Body hair includes any other kinds of hair (facial, axillary, etc.).

Process Overview

The principal phases in the laboratory processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab's system. This stage ensures the sample is correctly sealed and transported, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any missing data entry not supplied via an electronic chain of custody.

Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening efficiently excludes substance use in most cases, a positive screen requires confirmation for admissibility in legal settings. Samples that are seemingly positive in Screening require further confirmation.

Samples with a presumptive positive outcome during the Screening are further processed by retrieving additional hair from the original specimen for Extraction. At this phase, drugs are extracted from the hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug screening the most challenging test to conduct.

Positive results from Screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleaned before confirmation when necessary. The laboratory procedure from Accessioning to Confirmation undergoes supervision under the CAP (College of American Pathologists) Hair criteria and alignment with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests identify drug use spanning up to 90 days, unlike urine tests that have a more limited detection span.
• Challenging to manipulate: Cheating a hair drug test is considerably difficult, enhancing result accuracy.
• Tracks usage history: It reveals drug use patterns over an extended timeframe, not merely recent use.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug tests typically cost more than alternative drug-testing techniques.
• Result variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Despite common references as "hair follicle tests", the actual analysis focuses on the hair strand rather than 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.
