Hair Follicle Drug Testing - Trumbauersville, PA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within its fibers, offering long-term insights into drug and alcohol intake. A sample collected near the scalp can reflect up to a three-month detection period for substances. Hair is easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch section comprising roughly 200 hairs (approximately as wide as a #2 pencil) near the scalp provides around 100mg of hair, the preferred amount for testing. For EtG, additional checks, and exams exceeding 10 panels, 150mg of hair is advised. It is recommended to weigh the sample on a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be gathered. In discussions of head hair, it pertains only to scalp hair. Body hair encompasses all other varieties, including facial and axillary hair, among others.

Process Overview

The primary stages of laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a specimen within a lab's procedures. This stage ensures the sample is properly enclosed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any missing information not covered by an electronic custody tracking system.

Screening provides an expedited assessment for commonly abused substances. Although Screening is an economical means of ruling out drug use in many samples, positive results must be confirmed for legal acceptability. Samples testing presumptively positive in Screening require further confirmation.

At the Screening stage, if a sample indicates a presumptive positive result, additional hair is separated from the original sample for the Extraction process. During Extraction, drugs are isolated from hair at notably lower levels than other methods, such as urine or oral cavity samples, contributing to the complexity of hair drug evaluation.

Confirmation of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive specimens are cleaned prior to confirmation as necessary. The complete lab procedure from Accessioning through to Confirmation is evaluated according to both CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection period: Hair assessments can determine drug usage for up to 90 days, unlike urine tests which cover a briefer timeframe.
• High resistance to tampering: Cheating a hair drug test is exceedingly difficult, ensuring more dependable results.
• Tracks past usage: It can indicate a pattern of drug intake over time, not just recent activity.

Limitations:

• Inability to identify recent use: It typically takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug assays tend to be costlier than other testing methodologies.
• Result variability: Hair color and individual differences in hair growth may influence the levels of drug residues within the hair.

Note: Although commonly termed "hair follicle tests", the analysis examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine testing in Trumbauersville, PA? Hair testing benefits outweigh those of traditional urine tests through superior detection accuracy and reliability.

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.
