Hair Follicle Drug Testing - Nazareth, PA

What it is, How it works

Hair testing is regarded as a potent method for identifying drug and alcohol consumption. It provides an extended history of these substances by encasing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair samples offer an approximately 3-month detection window for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A hair sample measuring 1.5 inches and consisting of about 200 strands (comparable to a #2 pencil) near the scalp yields 100mg, the preferred quantity for screening and validation. For EtG add-ons and/or tests beyond 10 panels, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. In cases where scalp hair is lacking, an equivalent quantity of body hair can be collected. 'Head hair' refers exclusively to scalp hair, whereas 'body hair' includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the sample’s initial processing into the lab’s system. This step checks that the sample was correctly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry omitted by an electronic chain of custody system.

Screening provides an initial rapid check for drug use. Although cost-effective for eliminating drug use in most samples, a positive screen requires confirmation to be valid in legal situations. Any samples presumptively positive in Screening necessitate further confirmation.

If a sample is presumptively positive in the Screening process, additional hair is extracted from the primary specimen to prepare for Extraction. This stage involves extracting drugs from the hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging to execute.

Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive undergo washing before confirmation as necessary. The full lab process from Accessioning to Confirmation complies with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Resistance to cheating: Hair drug tests are hard to cheat, enhancing accuracy.
• Supplies historical data: It reveals a pattern of drug use over time, not just immediate use.

Limitations:

• Inability to spot recent use: It takes approximately 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests often cost more than alternative drug testing methods.
• Result variations: Factors like hair color and individual growth can impact drug metabolite concentrations in hair.

Note: Though commonly called "hair follicle tests", the test analyzes 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. 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.
