Hair Follicle Drug Testing - Goodville, PA

What it is, How it works

Hair testing is now recognized as an effective means of detecting drug and alcohol consumption. Hair traps biomarkers within the strands, capturing a long-term record of alcohol and other drugs. When collected near the scalp, hair can offer a detection window of up to three months for both alcohol and drugs. This method is straightforward to gather, moderately challenging to alter, and easy to transport.

A sample measuring 1.5 inches with approximately 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp yields around 100mg of hair, which is ideal for screening and confirming. For EtG, additional examinations, and/or tests exceeding 10 panels, 150mg of hair is advised. A jeweler's scale is recommended for measuring the sample weight. If scalp hair isn't accessible, a comparable quantity of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types (such as facial, axillary, etc.).

Process Overview

The four core steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a lab's system. This step verifies that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody.

Screening serves as a preliminary check for drug abuse. Though it is cost-effective for ruling out drug use in most samples, a positive result must be confirmed for legal admissibility. Presumptive positives in Screening necessitate a secondary confirmation.

When Screening shows a presumptive positive, additional hair is drawn from the original sample for Extraction. Here, drugs are sourced from hair at concentrations far lower than other methods (e.g., urine or oral fluid), making hair drug testing a highly complex methodology.

Positive results from Screening are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleaned before confirmation if necessary. The laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing reveals drug use for up to 90 days, unlike urine tests with shorter windows.
• Hard to manipulate: It is quite hard to falsify a hair drug test, enhancing the accuracy of results.
• Historic usage data: Provides insights into drug use patterns over a time span instead of just recent intake.

Limitations:

• Cannot detect recent intake: Drugs take around 5-7 days to become detectable in hair.
• Cost implications: Generally, hair drug tests are pricier than alternative drug testing methods.
• Variability in results: Hair color and individual hair growth variations can change drug metabolite levels in hair.

Note: Commonly called "hair follicle tests," the actual analysis is of the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine tests in Goodville, PA? The answer lies in detection consistency and dependability.

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.
