Hair Follicle Drug Testing - Seneca Knolls, NY

What it is, How it works

Hair testing is increasingly recognized as an effective method for spotting drug and alcohol use. Hair tracks a prolonged history of alcohol and drug exposure by embedding biomarkers within its growing fibers. When obtained near the scalp, hair can reveal up to a three-month detection timeframe for alcohol and drugs. It is straightforward to collect, relatively resistant to tampering, and easily transportable.

A 1.5-inch snip consisting of around 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, perfect for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a 150mg sample is suggested. We advise measuring the sample with a jeweler’s scale. If scalp hair is not available, an equivalent mass of body hair can be used. Head hair refers specifically to scalp hair, while body hair pertains to all other types (e.g., facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves introducing a sample into a lab’s database initially. This step includes ensuring the sample's proper sealing and shipment, assigning it a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not submitted via an electronic chain of custody.

Screening entails a preliminary swift assessment for drugs of abuse. While it’s a cost-efficient method to exclude drug use for most samples, a positive result needs confirmation to stand in court. Any samples testing presumptively positive during Screening require further confirmation.

If a sample tests presumptive positive at the Screening stage, additional hair is extracted from the original sample and readied for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing remains one of the most challenging methodologies.

Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. From Accessioning to Confirmation, the entire lab process is evaluated under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can detect drug use for up to 90 days, unlike urine tests which have a briefer detection period.
• Difficult to manipulate: Hair drug testing is very hard to deceive, thus yielding more reliable results.
• Offers historical insight: It can present a trend of drug use over time, rather than just recent consumption.

Limitations:

• Unable to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be costlier than alternative drug testing approaches.
• Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the actual analysis targets 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.
