Hair Follicle Drug Testing - Jemison, AL

What it is, How it works

The utilization of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended historical record of such substances by capturing biomarkers within the fibers of the strand as it grows. When sourced near the scalp, hair can offer near a 3-month period of alcohol and drug detection. Hair collection is straightforward, relatively challenging to tamper with, and convenient to send.

A length of 1.5 inches encompassing approximately 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is optimal for screening and validation. For EtG, additional tests, and/or those that exceed 10 panels, 150mg is suggested. We advise ensuring the sample’s weight using a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses any other types (facial, axillary, etc.).

Process Overview

The procedure for laboratory processing of a drug test result consists of four principal steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the laboratory system. This step includes verifying that the sample is sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and filling any additional data not captured by an electronic chain of custody system.

Screening constitutes a preliminary inspection for drugs of misuse. Although Screening is an economical method to discard drug usage among most samples, a positive screen requires confirmation to be court-admissible. Every sample indicating a presumptive positive in Screening necessitates an extra verification.

Should a sample indicate a presumptive positive at the Screening level, additional hair is extracted from the original sample to prepare for Extraction. In this step, drugs are retrieved from hair at much lower concentrations than alternative methods (such as urine or oral fluid), underscoring hair drug screening as a complex methodology to carry out.

Verification of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptively positive samples undergo washing prior to confirmation when necessary. The comprehensive laboratory journey from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair description and maintains the accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests may identify drug use up to 90 days, unlike urine tests which have a shorter range of detection.
• Challenge to deceive: Cheating a hair drug test proves highly difficult, ensuring result accuracy.
• Yields historical insight: It offers a temporal pattern of drug utilization beyond just recent usage.

Limitations:

• Incapable of detecting recent consumption: Drugs generally become detectable in hair approximately 5-7 days post-intake.
• Expense: Generally, hair drug tests incur higher costs compared to alternative drug testing approaches.
• Result variability: Elements like hair color and individual hair growth differences can impact the concentration of drug metabolites in hair.

Note: Despite the frequent mention as "hair follicle tests", the analysis narrowly focuses on the hair strand, excluding the follicle under 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.
