Hair Follicle Drug Testing - Odessa, NE

What it is, How it works

The perception of hair testing as an effective method for identifying drug and alcohol consumption has grown. Hair offers a chronicle of alcohol and drug use by embedding biomarkers within the strands. When collected near the scalp, a hair sample can reveal up to a 3-month detection period for substances. Hair collection is straightforward, challenging to tamper with, and convenient for transport.

A sample of 1.5 inches, approximately 200 strands (the size of a #2 pencil) near the scalp, equates to 100mg of hair—ideal for both screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not an option, an equivalent amount of body hair can be used. By head hair, we mean only scalp hair; body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

There are four primary steps in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is registered into the laboratory system. This involves confirming that the sample has been sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entry not available via an electronic chain of custody system.

The Screening phase consists of a preliminary check for common drugs of abuse. Though cost-effective, any positive screen result must be confirmed for legal use. Samples that are presumptively positive during Screening require further confirmation.

In cases where a sample is presumptively positive at the Screening phase, additional hair from the initial sample is prepared for Extraction. This step retrieves drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug tests complex to conduct.

Positive screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire process from Accessioning to Confirmation is conducted following guidelines from CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection range.
• Increased test integrity: Cheating a hair drug test is very difficult, ensuring more precise results.
• Historical insight: Hair tests can show a pattern of drug use over time, rather than just recent usage.

Limitations:

• Cannot identify recent use: It takes around 5-7 days for drugs to become detectable in hair.
• Expensive option: Generally, hair drug tests cost more than other drug testing methods.
• Result variability: Factors like hair color and individual growth variations can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", such tests actually analyze the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Odessa, NE, the superiority of hair follicle testing over conventional urine tests is clear. With enhanced detection capacities, hair tests offer longer accuracy. Urine tests might catch recent use, but hair tests identify much further back. Employers benefit from greater reliability and precision, helping maintain a drug-free environment.

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.
