Hair Follicle Drug Testing - North Crows Nest, IN

What it is, How it works

Hair testing is now regarded as an effective method for identifying drug and alcohol use. Hair captures a prolonged history of alcohol and drugs by securing biomarkers within the fibers of the hair strand as it grows. When collected from near the scalp, hair can reveal up to an estimated 3-month window for alcohol and other drugs detection. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.

A 1.5-inch sample, consisting of roughly 200 hair strands (approximating a #2 pencil size) close to the scalp, will yield 100mg of hair, which is the optimal sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest weighing the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair may be gathered. Head hair specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result features four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a laboratory’s system. This process involves confirming that the sample was appropriately sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening involves a preliminary quick assessment for drug abuse. Although Screening offers a cost-efficient means to negate drug usage in most samples, a positive screen necessitates confirmation to be legally acceptable. Samples presumed positive in Screening do require a secondary confirmation.

If a sample shows a presumptive positive at the Screening phase, additional hair is taken from the initial specimen and prepared for Extraction. Here, drugs are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to implement.

To confirm any positive screening result, GC/MS, GC/MS/MS, or LC/MS/MS is utilized. All presumptive positive samples are cleansed prior to confirmation if needed. The full laboratory procedure from Accessioning to Confirmation observes both CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for a duration of up to 90 days, unlike urine tests which have a shorter detection window.
• Hard to falsify: Cheating a hair drug test is extremely challenging, ensuring more accurate results.
• Historical data provision: It can offer a trend of drug use over a period of time, rather than just recent use.

Limitations:

• Recent use undetectable: It requires roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to cost more than other drug testing methods.
• Result variations: Elements like hair color and individual growth rate can influence drug metabolite concentration in hair.

Note: Commonly referred to as "hair follicle tests", the test examines the hair strand rather than the hair 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.
