Hair Follicle Drug Testing - Ensenada, NM

What it is, How it works

Utilizing hair analysis is regarded as a potent method for uncovering drug and alcohol consumption. Hair captures biomarkers in the strands of growing hair, offering a prolonged record of alcohol and drug presence. When taken from near the scalp, hair reveals a detection span for alcohol and drugs reaching approximately three months. Gathering is straightforward, tampering is somewhat challenging, and transit is convenient.

Extracting a 1.5-inch portion of around 200 hair strands (similar to the thickness of a #2 pencil) near the scalp yields 100mg, perfect for both screening and confirming. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We advocate for measuring the sample's weight with a jeweler’s scale. If scalp hair isn't obtainable, the same quantity of body hair may be utilized. Head hair exclusively denotes scalp hair. Body hair encompasses all other variants (facial, axillary, etc.).

Process Overview

The laboratory journey from initial sample to drug test result comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of introducing a sample into the laboratory's workflow. This ensures samples are appropriately sealed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any requisite data entry not managed by an electronic custody chain system.

Screening signifies a preliminary swift check for drug presence. While Screening is an affordable method to dismiss drug activity in many cases, any positive findings demand confirmation for legal acceptance. Samples identified as positive during Screening necessitate further verification.

When a sample shows a positive result in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, the drug is isolated from hair in significantly lower concentrations compared to other techniques (e.g., urine or saliva), underscoring the complexity of performing hair drug screening.

Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All positive presumptive samples are cleansed before confirmation if required. The comprehensive laboratory method, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair guidelines and meets ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair analysis can trace drug usage up to 90 days, whereas urine analysis offers a shorter span.
• Resistance to deception: Cheating in hair drug testing is notably difficult, thus ensuring more reliable results.
• Chronological insights: Offers a pattern of substance use over time rather than merely recent activity.

Limitations:

• Incapable of spotting recent consumption: Detection in hair requires approximately 5-7 days post-drug use.
• Expense: Hair drug analysis tends to be costlier than alternate drug testing techniques.
• Result variability: Hair color discrepancies and individual variations in hair growth can influence drug metabolite concentration.

Note: Frequently termed as "hair follicle tests", the analysis targets the hair strand itself, not the follicle located 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.
