Hair Follicle Drug Testing - Cathcart, WA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair records a prolonged history of alcohol and drug use by encapsulating biomarkers within the strands as they grow. A sample taken near the scalp can reveal usage over a period of up to three months for alcohol and other drugs. Collecting hair is straightforward, manipulating results is challenging, and transporting is hassle-free.

A 1.5-inch strand sample, comprising roughly 200 strands (comparable to the width of a #2 pencil) nearest to the scalp, offers about 100mg of hair, the optimal amount for analysis and verification. For EtG, additional tests, or panels exceeding 10, it is advised to collect 150mg of the sample. Using a jeweler’s scale is recommended for measuring the sample's weight. If head hair is not an option, a similar quantity of body hair can be collected. Head hair refers exclusively to scalp hair, while body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The laboratory evaluation of a drug test result involves four critical phases: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially integrated into the laboratory’s system. This entails confirming the sample was adequately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.

Screening involves a preliminary assessment for drugs of abuse. While it is a cost-effective approach to eliminate drug use in most samples, a positive screening must be validated for legal acceptability. Samples that presumptively test positive require additional verification through confirmation.

When a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen to prepare for Extraction. In this step, drugs are isolated from hair at much lower concentrations than in other testing methods (such as urine or oral fluid), making hair drug testing a more complex procedure.

Verification of a positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing presumptive positive are cleansed before verification as necessary. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
• Testing integrity: Cheating on a hair drug test is nearly impossible, enhancing the accuracy of results.
• Data over time: It offers insights into drug usage patterns over time, rather than a snapshot of recent use only.

Limitations:

• No recent use detection: Drugs take roughly 5-7 days to appear in hair.
• Expense: Hair drug tests typically cost more than alternative drug testing approaches.
• Result variations: Factors like hair color and individual hair growth can influence drug metabolite concentrations in hair.

Note: Although called "hair follicle tests", these tests examine the hair strand, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outshine urine testing in Cathcart, WA? Hair testing is superior due to its high accuracy and reliability in detecting substances over a longer period.

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.
