Hair Follicle Drug Testing - Crowders, NC

What it is, How it works

Analyzing drug and alcohol consumption through hair testing is increasingly recognized as an effective method. The fibers of hair strands, as they grow, encapsulate biomarkers, offering a prolonged record of substance use. When sourced close to the scalp, hair provides an opportunity for detection of alcohol and drugs spanning up to roughly three months. Hair collection is straightforward, hard to tamper with, and convenient to transport.

To conduct screening and confirmation, a sample measuring 1.5 inches with about 200 strands (equivalent to a #2 pencil thickness) near the scalp provides 100mg of hair, considered ideal. For EtG analyses, supplementary tests, or those exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to measure the sample is recommended. Should scalp hair be inaccessible, a similar quantity of body hair is acceptable. Note that “head hair” exclusively refers to scalp hair, whereas "body hair" includes all other types (e.g., facial, axillary, etc.).

Process Overview

The laboratory process of determining a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial stage where a sample is integrated into a laboratory system. Steps include verifying secure sealing and safe shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and executing any leftover data recording not addressed by an electronic tracking system.

Screening involves the preliminary assessment for drugs of abuse. Although Screening effectively rules out drug presence in most samples, a positive result must undergo confirmation for legal validity. Presumptive positives in Screening require further verification.

Should Screening suggest a positive result, additional hair from the primary sample undergoes Extraction. Drugs are extracted from hair in significantly lower concentrations than in alternatives such as urine or saliva tests, underscoring the complexity of hair drug screening.

Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed prior to Confirmation if necessary. The entire lab workflow from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Capable of detecting drug use for up to 90 days, hair tests offer a longer detection period than urine tests.
• Resilient to tampering: Manipulating hair test results is highly challenging, thus ensuring more reliable outcomes.
• Tracks historical data: Hair tests reveal drug use patterns across a timeline, not just recent consumption.

Limitations:

• Incapable of identifying recent use: Drugs become traceable in hair within approximately 5-7 days.
• Expenses: Hair drug testing typically incurs higher costs than other testing methods.
• Result variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentration.

Note: Although the term "hair follicle tests" is frequently used, the analysis focuses on the hair strand, 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.
