Hair Follicle Drug Testing - Cromwell, IN

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol usage. By capturing specific biomarkers within the fibers of growing hair, it offers a prolonged timeline of such usage. When hair is gathered close to the scalp, it can reveal up to a 3-month window for detecting alcohol and drug intake. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A well-suited sample consists of a 1.5-inch section of about 200 hair strands (roughly the circumference of a #2 pencil) nearest the scalp, which equates to 100mg of hair — ideal for analysis in both screening and confirmation. For EtG assessments, additional tests, and those over 10 panels, 150mg of the sample is preferable. It's advisable to weigh the hair sample using a jeweler's scale. Should scalp hair not be available, a similar quantity of body hair may be used. References to head hair indicate scalp hair exclusively, while body hair refers to other types (such as facial, axillary, etc.).

Process Overview

There are four fundamental phases in the laboratory analysis of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is where the sample is initially integrated into the laboratory's system. This step confirms that the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and includes any supplementary data entry not covered by an electronic chain of custody.

Screening provides a preliminary examination for drugs. While Screening is a practical method to eliminate drug use for many samples, any positive findings must be confirmed for legal admissibility. Samples showing presumptive positives in Screening require further confirmation.

Samples with presumptive positive results in the Screening phase have additional hair taken from the original specimen and prepared for Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), explaining why hair drug screening is the most complex to conduct.

Confirmation of a positive screen result uses GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleaned before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is evaluated following CAP (College of American Pathologists) Hair designation standards and is accredited to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, whereas urine tests offer a shorter detection span.
• Immunity to deception: Hair drug tests are hard to falsify, resulting in more reliable outcomes.
• Reflects historical usage: It illustrates a usage pattern of drugs over time, not just recent consumption.

Limitations:

• Cannot identify recent consumption: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than other testing approaches.
• Result variability: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Referred to as "hair follicle tests", the analysis evaluates the hair strand, 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.
