Hair Follicle Drug Testing - Lilita, AL

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol use. Hair offers an extended history of alcohol and drugs by embedding biomarkers in the strands of growing hair. When sourced near the scalp, hair can indicate alcohol and drug usage within an approximate 3-month period. Hair sampling is straightforward, challenging to tamper with, and convenient to transport.

By collecting a 1.5-inch sample of approximately 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp, one can obtain 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the specimen with a jeweler’s scale. If scalp hair can't be provided, a comparable quantity of body hair may be gathered. In the context of head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial incorporation of a sample into a laboratory's system. This step ensures that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not covered by an electronic chain of custody system.

Screening performs an initial rapid check for drug use. While Screening is a cost-effective method to eliminate drug use for most samples, any positive screen needs confirmation to be legally admissible. Any samples with presumptive positive results in Screening require further confirmation.

If a sample returns a presumptively positive result during Screening, additional hair is drawn from the original specimen for preparation in the Extraction phase. Here, drugs are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug testing a challenging methodology.

Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positive results are cleansed before confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Lengthy detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests which have a shorter period of detection.
• Challenging to manipulate: Cheating a hair drug test is extremely difficult, ensuring more precise results.
• Offers historical insights: It can reveal a timeline of drug usage over time, as opposed to only recent usage.

Limitations:

• Inability to detect recent consumption: It requires around 5-7 days for drugs to become noticeable in hair.
• Higher costs: Hair drug tests tend to be pricier than other drug testing techniques.
• Possible result discrepancies: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though commonly termed as "hair follicle tests", the methodology examines the hair strand and not the underlying scalp follicle.

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.
