Hair Follicle Drug Testing - Riverton, OR

What it is, How it works

Recognized as an effective means to identify drug and alcohol consumption, hair testing captures a history of substance use over time by encapsulating biomarkers in the hair strand's developing fibers. When taken near the scalp, hair enables as much as a three-month detection timeframe for alcohol and drugs. It is straightforward to gather, moderately hard to tamper with, and convenient to transport.

A 1.5-inch hair sample consisting of approximately 200 strands (similar in diameter to a #2 pencil) near the scalp will yield 100mg, the optimal amount for both screening and verification. For EtG, extras, and/or assessments exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for specimen weighing is advisable. In cases where scalp hair is absent, an equivalent body hair amount can be obtained. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial phase of integrating a sample into a laboratory database. This step ensures the sample's sealing and shipment are accurately handled, assigns a unique LAN (Laboratory Accessioning Number), and enters any additional data absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for substance misuse. While Screening is an economical approach to eliminate drug use in most cases, a positive Screening needs validation to be legally acceptable. Samples that are conditionally positive in Screening necessitate further confirmation.

Should a sample reflect a conditional positive in the Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair in notably lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing presents greater challenges.

Verification of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All conditionally positive samples are cleansed prior to confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for as long as 90 days, versus urine tests which offer a shorter timeframe.
• Difficult to evade: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Offers usage history: It shows a drug use trend over time, rather than solely focusing on immediate use.

Limitations:

• Cannot detect recent use: Detecting drugs in hair takes about 5-7 days.
• Cost: Hair drug tests are generally pricier than alternative testing methods.
• Result variability: Elements such as hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Often called "hair follicle tests," the analysis targets the hair strand, not the scalp's hair follicle.

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. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
