Hair Follicle Drug Testing - Providence, KY

What it is, How it works

Hair analysis is acclaimed as an effective instrument for identifying drug and alcohol usage. Hair encapsulates a prolonged record of alcohol and drug intake by embedding biomarkers within the strands of the hair as it grows. When sourced near the scalp, hair offers an approximate 3-month window of detection for substances such as alcohol and drugs. Hair collection is straightforward, moderately resistant to tampering, and conveniently transportable.

A 1.5-inch hair sample, comprising roughly 200 strands (comparable to the thickness of a #2 pencil) and taken nearest the scalp, delivers 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG tests, additional tests, and/or those exceeding 10 panels, a 150mg sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be collected. Head hair refers exclusively to scalp hair, while body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory process of drug testing involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial entry of a sample into the laboratory system. This step ensures the proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and completes any necessary additional data entry not covered by an electronic chain of custody system.

Screening involves a preliminary check for drugs of abuse. While Screening provides a cost-effective approach to eliminate drug use in most samples, any positive screen requires confirmation to be court-admissible. Samples deemed presumptively positive during Screening necessitate an additional confirmation.

If a sample tests presumptively positive during Screening, further hair is utilized from the original sample for the Extraction process. Here, drugs are extracted from the hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), highlighting why hair drug testing is among the most challenging methods to execute.

Confirmation for any positive screening result is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation if needed. The entire laboratory process covering Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests can track drug use for up to 90 days, unlike urine tests with shorter detection ranges.
• Hard to manipulate: Cheating a hair drug test is quite challenging, leading to more precise results.
• Offers historical insights: This method can reveal drug use patterns over time instead of just recent usage.

Limitations:

• Inability to spot recent use: It requires about 5-7 days for drugs to show up in hair samples.
• Expense: Hair drug tests tend to be pricier compared to other testing techniques.
• Result variability: Factors like hair color and individual variations in hair growth can influence metabolite concentration in hair.

Note: While commonly known as "hair follicle tests", these tests analyze the hair strand and not 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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
