Hair Follicle Drug Testing - Coldstream, KY

What it is, How it works

Hair sampling is perceived as an effective instrument for identifying the presence of drugs and alcohol. Hair offers a prolonged record of alcohol and drug consumption by encapsulating biomarkers within the strands as hair grows. Hair samples taken close to the scalp can provide a detection timeframe for up to around three months for both alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A hair sample measuring 1.5 inches, consisting of roughly 200 strands (comparable in size to a #2 pencil) at the point closest to the scalp, yields 100mg of hair, the optimal sample size for both screening and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg is preferred. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair is a suitable alternative. When we mention head hair, it specifically pertains to scalp hair. Body hair encompasses any other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the sample’s initial entry into the laboratory system, confirming the sample’s proper seal and shipment, allocating a random Laboratory Accessioning Number (LAN), and managing any further data not provided through an electronic chain of custody system.

Screening executes a preliminary rapid assessment for substance abuse. Although Screening serves as a cost-effective means to exclude drug use among most samples, a positive screen necessitates confirmation for legal admissibility. Samples that yield a presumptive positive in Screening do require subsequent confirmation.

In instances where a sample emerges as presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. During this phase, drugs are isolated from hair at considerably lower concentrations than other methods (such as urine or oral fluids), signifying that hair drug analysis is amongst the most intricate methodologies.

Confirmation, following a positive screen, is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. Presumably positive samples undergo washing prior to confirmation as required. The comprehensive laboratory sequence, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation along with the accreditation standards of ISO / IEC 17025.

Benefits of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug presence for as long as 90 days, while urine tests have a shorter detection period.
• Difficult to manipulate: Hair drug assessments are harder to falsify, enhancing the precision of results.
• Offers historical insight: It presents a pattern of drug intake over time rather than only recent consumption.

Drawbacks:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug analyses are typically pricier than other drug testing techniques.
• Result variability: Variables like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although frequently termed "hair follicle tests", this test evaluates the strand itself, 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.
