Hair Follicle Drug Testing - Fresno, OH

What it is, How it works

Hair testing has gained recognition as an effective mechanism for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug usage by embedding biomarkers within the strands as it grows. By gathering hair near the scalp, one can achieve an estimated 3-month detection period for alcohol and drugs. Hair is easy to obtain, relatively resistant to tampering, and conveniently transportable.

A 1.5-inch section consisting of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp is ideal for providing 100mg of hair, which is the preferred sample quantity for both screening and confirmation. For EtG, supplemental tests, and tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest the specimen be measured on a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair only. Body hair encompasses other hair types (e.g., facial, axillary).

Process Overview

The pivotal steps in the laboratory's handling of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a laboratory's workflow, which includes ensuring the sample was properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input absent from an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient method to eliminate drug presence in most samples, a positive screen must undergo confirmation to be valid in legal contexts. Samples that test presumptively positive in Screening require further confirmation.

Should a sample indicate a presumptive positive in the Screening phase, additional hair is removed from the original specimen and made ready for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug testing a challenging methodology to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory protocol from Accessioning to Confirmation undergoes evaluation according to both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, as opposed to urine tests which offer a narrower window.
• Resistance to manipulation: It is exceedingly challenging to deceive a hair drug test, resulting in more reliable outcomes.
• Offers a historical record: It provides a timeline of drug consumption across an extended timeframe, rather than indicating only recent use.

Limitations:

• Inability to detect recent usage: It generally requires 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests tend to be pricier compared to alternative drug testing approaches.
• Result variability: Elements such as hair color and individual differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Even though frequently dubbed "hair follicle tests", the analysis actually examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Fresno, OH, surpasses urine testing by providing better 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. 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.
