Hair Follicle Drug Testing - Villa Hills, KY

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of a growing hair strand, hair offers a long-term record of alcohol and drug use. When collected near the scalp, hair can offer a detection timeframe reaching up to roughly three months for alcohol and drug usage. Collecting hair is straightforward, tampering is relatively challenging, and shipping is simple.

A hair sample measuring 1.5 inches and comprising approximately 200 strands (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, and/or when conducting tests above 10 panels, a specimen weighing 150mg is advised. Utilizing a jeweler's scale for specimen weighing is suggested. Should scalp hair be nonexistent, an equivalent volume of body hair may be gathered. Reference to head hair strictly indicates scalp hair. Body hair pertains to all other varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure to produce a drug test result comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary incorporation of a sample into a laboratory’s database. This process includes ensuring the sample was correctly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent from an electronic chain of custody system.

Screening involves a preliminary inspection for drugs of abuse. While Screening is cost-effective for excluding drug use in most samples, a positive screen requires confirmation to be court-admissible. Any samples preliminarily positive in Screening necessitate further confirmation.

In instances where a sample is preliminarily positive during Screening, more hair is extracted from the original specimen and readied for Extraction. At this phase, drugs are isolated from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), making hair drug screening particularly challenging to execute.

For Confirmation of any positive screening result, methods employed include GC/MS, GC/MS/MS, or LC/MS/MS. Any samples showing presumptive positives are cleansed as necessary before Confirmation. Every stage of the laboratory procedure from Accessioning to Confirmation is evaluated under the oversight of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests reveal drug use for up to 90 days, whereas urine tests offer a briefer detection period.
• Challenging to falsify: Hair drug tests are exceptionally resistant to tampering, ensuring more precise results.
• Delivers historical insights: Offers a timeline of drug use patterns over extended periods, beyond just recent activity.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests," the assessment focuses on analyzing 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.
