Hair Follicle Drug Testing - Danville, OH

What it is, How it works

Hair analysis is now regarded as an effective means for identifying drug and alcohol consumption. It captures a historical record of substance use by embedding biomarkers within the strands of growing hair. When hair is sampled near the scalp, it may offer a detection range up to about three months for alcohol and drugs. Collecting hair is straightforward, generally resistant to tampering, and convenient to dispatch.

A hair sample of 1.5 inches, consisting of approximately 200 strands (similar to a #2 pencil's thickness) nearest to the scalp provides 100mg of hair, which is considered the ideal sample size for both initial screening and further confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale is recommended for weighing the specimen. Should scalp hair not be available, a comparable amount of body hair can be taken. Head hair exclusively refers to scalp hair, while body hair encompasses all other types such as facial and axillary.

Process Overview

The key phases involved in laboratory testing of a drug sample result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial input of a specimen into the laboratory system. It confirms the sample was properly sealed and sent, allocates a random LAN (Laboratory Accessioning Number), and fulfills any remaining data entry not supported by an electronic chain of custody.

Screening offers a preliminary assessment for substance abuse. Although Screening provides a cost-efficient method to exclude drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Samples with questionable positive results during Screening must undergo secondary verification.

After a sample tests potentially positive during Screening, additional hair is extracted from the original sample for the Extraction phase. In this phase, chemicals are retrieved from hair at significantly lower levels than in methods like urine or oral fluid, making hair drug tests one of the most challenging techniques to execute.

For Confirmation of any positive results, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are used. All potential positive samples are cleaned before confirmation if required. The entire procedure from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect substance use for up to 90 days, which is longer than the detection period for urine tests.
• Hard to deceive: Compromising a hair drug test is very challenging, resulting in high accuracy.
• Provides usage history: It can show a pattern of drug use over time, beyond just recent use.

Limitations:

• Inability to detect recent use: Drugs need around 5-7 days to become noticeable in hair.
• Expense: Hair drug tests are usually pricier compared to other drug testing approaches.
• Result variations: Elements like hair color and differences in individual hair growth can influence drug metabolite concentrations in hair.

Note: While commonly known as "hair follicle tests", the analysis is done on the hair strand, not the follicle under 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.
