Hair Follicle Drug Testing - Westfield, TX

What it is, How it works

Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. Hair serves as a long-term repository of drug and alcohol markers by embedding biomarkers within the strands as hair grows. When collected near the scalp, hair can offer an approximate 3-month detection period for substances like alcohol. The collection of hair is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) closest to the scalp results in 100mg of hair, which is the optimal sample size for screening and confirmation. In cases involving EtG, additional testing, and/or tests exceeding 10 panels, a specimen quantity of 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is absent, a similar amount of body hair can be collected. It is important to note that when mentioning head hair, we only refer to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four fundamental steps in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into the laboratory’s system. This process includes verification of the sample’s seal and proper shipment, assignment of a random LAN (Laboratory Accessioning Number), and completion of any missing data entry not covered by an electronic chain of custody system.

Screening comprises a preliminary rapid check for drugs of abuse. Although Screening is a cost-efficient method to potentially exclude drug use in the majority of samples, a positive screen necessitates confirmation to be court-admissible. Presumptively positive Screening samples require subsequent confirmation.

If the sample appears positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. During Extraction, drugs are withdrawn from the hair at significantly lower concentrations than other methods (such as urine or oral fluid), which makes hair drug screening a challenging methodology.

Confirmation of any positive Screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptively positive undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for up to 90 days, unlike urine tests that have a shorter detection period.
• Challenging to circumvent: Cheating a hair test is hard, leading to more reliable results.
• Offers historic data: It reflects a pattern of drug usage over time, rather than just recent use.

Limitations:

• Inability to detect recent usage: It takes about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests typically carry a higher cost than other testing methods.
• Result variabilities: Factors like hair color and individual growth rates can impact drug metabolite concentrations in hair.

Note: Often referred to as "hair follicle tests", the examination focuses on analyzing the hair strand, not the follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Westfield, TX

Hair testing stands out as a superior alternative to urine tests due to its unmatched detection accuracy and dependability. Unlike urine tests, which may only identify recent consumption, hair follicle tests unveil a broader history of substance use. This makes them an ideal choice for environments prioritizing rigorous testing measures and long-term vigilance.

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.
