Hair Follicle Drug Testing - Hobart, OK

What it is, How it works

Hair testing has become recognized as a robust method for identifying drug and alcohol consumption. Hair offers a prolonged record of substance use by capturing biomarkers within the strands of hair as they grow. When cut near the scalp, hair can reveal a detection period of up to roughly three months for alcohol and other substances. Collecting hair is straightforward, it's moderately hard to tamper with, and it can be easily transported.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp will yield 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair isn’t available, a similar quantity of body hair can be collected. When mentioning head hair, we mean scalp hair only. Body hair pertains to all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning covers the initial sample processing into a lab’s system. This step verifies that the sample was properly sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and completes any further data input not covered by an electronic chain of custody system.

Screening consists of a rapid preliminary check for prohibited substances. Though Screening is a cost-efficient way to exclude drug use in most samples, a positive screen must be validated to be considered in court. Samples that are presumptively positive during Screening necessitate secondary confirmation.

If a sample is tentatively positive during the Screening phase, more hair is taken from the original sample for Extraction. During Extraction, substances are drawn out from hair at a notably lower concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.

Positive screening confirmations are carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can recognize drug use for up to 90 days, whereas urine tests have a shorter detection span.
• Hard to deceive: Attempting to manipulate a hair drug test is exceptionally difficult, leading to more reliable results.
• Yields historical insights: It can show a usage pattern over time, not just recent consumption.

Limitations:

• Cannot detect new usage: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug screens are often pricier than other drug testing methods.
• Variability in outcomes: Elements like hair color and individual growth differences can influence drug metabolite levels in the hair.

Note: Often termed "hair follicle tests", the test actually examines the hair strand and not the follicle beneath the skin.

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.
