Hair Follicle Drug Testing - Mount Spokane, WA

What it is, How it works

Hair analysis has become recognized as a potent method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance intake by capturing biomarkers within the structure of the growing hair. When taken near the scalp, hair can reveal up to a 90-day window for detecting alcohol and drugs. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to send.

A 1.5-inch collection of roughly 200 hair strands (about the circumference of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred amount for assessment and confirmation. For EtG, additional screenings, and/or tests beyond 10 panels, a 150mg sample is advised. It's suggested to weigh the hair using a jeweler’s scale. If scalp hair isn’t available, a similar quantity of body hair may be used. When mentioning head hair, it pertains solely to scalp hair. Body hair refers to any other hair types (facial, underarm, etc.).

Process Overview

The sequence for lab processing of a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where the sample is incorporated into the lab’s system. This step verifies sample sealing and accurate shipping, assigns a LAN (Laboratory Accessioning Number), and completes any further data entry not covered by electronic custody systems.

Screening provides a preliminary assessment for drugs of abuse. Although Screening is an economical approach to eliminate drug presence in most samples, any positive findings must be confirmed for court validity. Presumptive positives in Screening must undergo a secondary confirmation.

With presumptive positive results at the Screening phase, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are isolated from hair, at much lower levels than in other methods (e.g., urine or saliva), making hair drug testing the most challenging technique to perform.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives receive a wash before confirmation if necessary. The total lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use for up to 90 days, unlike urine tests that have a briefer detection timeframe.
• Hard to bypass: Cheating a hair drug test is very challenging, ensuring more precise results.
• Offers past data: Hair testing can show drug usage patterns over time, beyond just recent use.

Limitations:

• Inability to detect recent intake: Detected drugs in hair take around 5-7 days to appear.
• Expense: Hair drug tests tend to be costlier than other testing methods.
• Result fluctuations: Aspects like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although termed "hair follicle tests", the procedure examines 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
