Hair Follicle Drug Testing - Hillsboro, OR

What it is, How it works

Hair testing is widely recognized as a robust method for detecting drug and alcohol use. It offers an extended history of substance use by capturing biomarkers within the fibers of the growing hair strand. Hair collected near the scalp can reveal drug and alcohol usage for up to three months. The collection is simple, difficult to tamper with, and straightforward to transport.

A sample of 1.5 inches containing approximately 200 strands of hair (similar in size to a #2 pencil) near the scalp yields 100mg, which is optimal for screening and verification. For EtG, add-ons, or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler's scale for weighing the specimen. If scalp hair is not obtainable, an equivalent amount of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" covers all other hair types (facial, axillary, etc.).

Process Overview

The principal stages in laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into the laboratory system. This step involves verifying sample sealing and proper shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not present in the electronic chain of custody system.

Screening performs an initial check for the presence of drug abuse. Although Screening is an economical approach to exclude drug usage in most samples, court-admissibility requires confirming a positive screen. Samples presumed positive during Screening require secondary confirmation.

If the Screening stage indicates a presumptive positive result, additional hair is drawn from the original sample for Extraction. In this phase, drug extraction from hair occurs at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing particularly challenging.

Confirmation of any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a washing process before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use for up to 90 days, whereas urine tests offer a shorter window.
• Challenging to falsify: Hair drug tests are difficult to manipulate, resulting in more reliable outcomes.
• Historical data provision: This method can reveal drug use patterns over an extended period rather than just recent use.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug testing is typically more costly than other testing methods.
• Result variations: Factors like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Though often called "hair follicle tests," the analysis targets the hair strand, 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.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
