Hair Follicle Drug Testing - Wauna, WA

What it is, How it works

Hair analyses are increasingly recognized as an effective method for identifying the use of drugs and alcohol. The hair captures a long-term record of these substances by embedding biomarkers within the fibers of the growing hair strands. When taken close to the scalp, hair can offer up to a 3-month window of detection for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to ship.

A sample of 1.5 inches comprising around 200 strands of hair (roughly the girth of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for screening and confirmation. For EtG, extended panels, or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest measuring the specimen with a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be taken. References to head hair indicate scalp hair exclusively. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of drug tests encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial integration into the lab's system. This consists of checking that the sample was securely sealed and correctly dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any further data input absent in an electronic chain of custody system.

Screening offers a preliminary quick assessment for drugs of abuse. While Screening is an economical approach to exclude drug usage across most samples, a positive indication requires confirmation to be valid in legal contexts. Samples flagged as presumptively positive during Screening necessitate a second confirmation.

If during Screening a sample is considered presumptively positive, more hair is extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at much lower concentrations than in other techniques (such as urine or oral fluid), making hair drug screening the most challenging technique to execute.

Confirmation of positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if required. The comprehensive lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, in contrast to urine tests that have a shorter detection period.
• Challenging to deceive: Tampering with a hair drug test is quite difficult, which enhances the accuracy of the outcomes.
• Historical data provision: It can illustrate a pattern of drug use across a duration, beyond just recent activity.

Limitations:

• Incapable of detecting recent use: It typically requires about 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests are generally pricier than other drug testing approaches.
• Result variability: Elements such as hair color and personal variations in hair growth may impact the levels of drug metabolites in the hair.

Note: Though commonly dubbed "hair follicle tests", the analysis focuses on the hair strand itself, 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.
