Hair Follicle Drug Testing - Canyon Park, WA

What it is, How it works

Hair strand analysis is recognized as an effective method for identifying drug and alcohol use. Hair fibers capture biomarkers within the growing strands, providing a long-term account of drug and alcohol usage. When taken near the scalp, hair can offer a detection period of up to roughly 90 days for alcohol and drugs. The collection process for hair is straightforward, challenging to tamper with, and simple to transport.

Using a 1.5-inch section of about 200 hairs (approximately the thickness of a #2 pencil) from just above the scalp provides a 100mg sample, an ideal quantity for initial and confirmatory testing. For EtG tests, additional panels, or assessments exceeding 10 panels, a 150mg sample is optimal. It's advisable to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be collected. Reference to head hair specifically denotes scalp hair, while body hair includes all other types (facial, armpit, etc.).

Process Overview

The processing of a drug test result in the lab comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initiation of sample processing within the lab system. This process ensures the sample was well-sealed and properly shipped, assigns a Laboratory Accessioning Number (LAN), and completes any missing data entry absent from an electronic chain of custody system.

Screening serves as an initial rapid assessment for the presence of drug abuse. While cost-effective for eliminating drug use in most specimens, a positive screen result must be confirmed to hold up in legal settings. Samples flagged as presumptively positive during Screening require further verification.

Should the Screening phase indicate a presumptive positive, additional hair is drawn from the original sample for Extraction. In this phase, drugs are refined from hair at much lower concentrations than other methods (such as urine or oral fluid), highlighting hair drug screening as the most complex method to execute.

To validate any positive screening findings, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Presumptively positive samples undergo washing prior to confirmation where necessary. Every step from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair classification and adheres to ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests sense drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Resistant to cheating: Hair drug tests are challenging to manipulate, ensuring more precise outcomes.
• Shows historical use: It provides a record of drug consumption over time, not just recent use.

Limitations:

• Incapable of recent use detection: Drugs take around 5-7 days to become noticeable in hair.
• Expense: Hair drug tests are typically costlier than alternative drug testing techniques.
• Result variability: Elements like hair color and individual hair growth differences can influence the concentration of drug residues in the hair.

Note: While frequently termed as "hair follicle tests", the analysis targets 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. 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.
