Hair Follicle Drug Testing - Southeast Osage, OK

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair can capture a long-term record of alcohol and drug biomarkers within the hair strand's fibers. When sampled near the scalp, hair can offer a detection timeframe of up to about three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. It's suggested to weigh the sample using a jeweler's scale. If scalp hair isn't available, a similar quantity of body hair can be used. When referring to head hair, it specifically means scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The drug test results process in the lab consists of Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial incorporation of a sample into the lab system. This includes ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. While Screening offers a cost-efficient way to dismiss drug use in the majority of samples, a positive screen is essential for admissibility in legal proceedings. Any samples that are presumptively positive in Screening must undergo secondary confirmation.

If identified as presumptively positive during the Screening phase, extra hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at a much lower concentration than other methods (e.g., urine or oral fluid), which accounts for hair drug screening being the most challenging methodology to perform.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptive positives are washed before confirmation as required. The lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use up to 90 days in contrast to the shorter detection window of urine tests.
• Difficulty to cheat: Cheating on a hair drug test is extremely challenging, ensuring more accurate results.
• Provides historical data: It displays a pattern of drug use over time and not just recent consumption.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Typically, hair drug tests are more expensive than other drug testing techniques.
• Variations in results: Factors like hair color and personal differences in hair growth can influence the drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," the analysis is performed on the hair strand rather than the follicle beneath the scalp.

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.
