Hair Follicle Drug Testing - Meadowdale, WA

What it is, How it works

Hair analysis is increasingly recognized as a crucial means for uncovering drug and alcohol consumption. Hair strands capture chemical indicators within their structure, providing an extended timeline of substance exposure. By collecting strands near the scalp, one can achieve a detection period up to roughly 90 days for substances. The collection process is straightforward, alteration is challenging, and it is convenient for shipping.

A sample of 1.5 inches with approximately 200 hairs (around the circumference of a #2 pencil) close to the scalp yields 100mg, which is the preferred amount for screening and verification. For tests like EtG, add-ons, or those with more than 10 panels, 150mg is advisable. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is not an option, a comparable quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

The primary steps in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary processing of a sample within a lab's framework. This phase includes checking the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data input absent in an electronic chain of custody framework.

Screening consists of an initial rapid assessment for drugs of abuse. Screening provides an economical way to eliminate drug presence in most samples, but results positive in Screening must be verified for legal acceptability. Those samples that test positive initially do need secondary verification.

When a sample tests presumptively positive during Screening, additional hair is taken from the original sample and prepared for Extraction. At this phase, substances are extracted from hair at significantly lower levels than with other methods (like urine or oral fluid), underscoring why hair drug testing presents the greatest challenge in execution.

Any positive Screening outcomes are verified via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suggesting a positive result are cleaned if necessary prior to confirmation. From Accessioning to Confirmation, the entire lab process is evaluated under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 guidelines.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, while urine tests have a significantly shorter detection window.
• Resistance to tampering: It is exceedingly hard to deceive a hair drug test, enhancing result reliability.
• Long-term use insights: It reveals patterns of substance use over time, unlike assessments based solely on recent use.

Limitations:

• Inability to detect recent use: Detection in hair typically begins 5-7 days post drug intake.
• Expense: Typically, hair drug testing is pricier compared to alternative methods.
• Disparities in outcomes: Variables such as hair color and individual hair growth rates can influence drug metabolite levels within hair samples.

Note: Although often called "hair follicle tests", the testing actually examines the hair strand, not the follicle situated beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The debate over Why Hair Follicle Testing Beats Urine Testing in Meadowdale, WA is ever-present. Hair testing provides a higher detection rate for substance presence. This reliability stems from its ability to capture long-term use rather than recent single-instance exposure, unlike traditional urine tests, which may miss long-term patterns of drug use.

Extended Detection Window

One advantage of hair follicle testing is its Extended Detection Window in Meadowdale, WA. By detecting drug traces over an extended period, often up to 90 days, employers can gain insight into a more comprehensive history of an individual's drug use. This extended detection is crucial for monitoring long-term abstinence and prior usage patterns.

Tamper-Resistant Testing Method

When it comes to Tamper-Resistant Testing Method in Meadowdale, WA, hair follicle tests offer a substantial benefit. Their design makes them less susceptible to adulteration or substitution when compared to urine tests. This built-in resistance ensures the reliability and integrity of the results, instilling confidence in employers and agencies alike.

Convenient Nationwide Locations

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.
