Hair Follicle Drug Testing - Larimer, PA

What it is, How it works

Hair analysis is increasingly recognized as an effective means for detecting substance and alcohol use. Hair retains a comprehensive record of alcohol and drug consumption by embedding biomarkers within the hair fibers as they grow. When collected near the scalp, hair can offer an approximately three-month detection period for both alcohol and drugs. Collecting hair is straightforward, tampering with it is relatively challenging, and it's convenient to transport.

To obtain an ideal sample for analysis, a 1.5-inch segment consisting of about 200 hair strands (similar in thickness to a #2 pencil) taken nearest the scalp should be collected, equaling 100mg of hair. For EtG, additional tests, and/or tests surpassing 10 panels, a specimen of 150mg is advised. It's suggested to weigh the hair sample using a jeweler’s scale. In the absence of scalp hair, a proportional amount of body hair may be utilized. References to head hair are exclusive to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the system incorporates the incoming sample, checks proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and finalizes any necessary data entry not available through an electronic chain of custody system.

Screening offers an initial drug abuse check. This cost-efficient approach helps preclude drug use in most samples, but a positive screening requires confirmation for legal admissibility. Samples identified as potentially positive in Screening necessitate secondary verification.

For a sample labeled presumptively positive in Screening, additional hair is extracted from the initial collection for the Extraction phase. In this phase, drug elements are isolated from hair at much lower concentrations than in other methods (e.g., urine or oral fluids), making hair drug screening particularly challenging to conduct.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleaned before confirmation as necessary. The entire process, from Accessioning through Confirmation, is scrutinized according to both CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage up to 90 days back, unlike urine tests with a shorter detection window.
• Challenging to tamper: Cheating a hair drug test is very difficult, enhancing accuracy.
• Supplies historical patterns: It delivers a usage history over time, rather than recent consumption only.

Limitations:

• Cannot indicate recent consumption: Drugs become detectable in hair roughly 5-7 days after use.
• Expense: Hair drug tests tend to be more costly than other drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," this analysis examines 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.
