Hair Follicle Drug Testing - Detroit, TX

What it is, How it works

The use of hair testing has emerged as an effective instrument for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the hair as it grows, hair provides an extended historical record of alcohol and other substance use. When hair is taken near the scalp, it offers an approximate three-month detection period for alcohol and other substances. Hair is straightforward to gather, harder to adulterate, and simple to transport.

An ideal testing sample comprises 1.5 inches of about 200 hair strands (similar in size to a #2 pencil) closest to the scalp, equating to 100mg of hair. For EtG, additional testing, or more than 10 panels, 150mg of the sample is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair can be collected. References to head hair exclusively denote scalp hair, whereas body hair encompasses any other hair type (facial, axillary, etc.).

Process Overview

The laboratory procedures for determining a drug test result involve four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a specimen within the lab's framework. This includes verifying the proper sealing and shipment of the sample, assigning it a random LAN (Laboratory Accessioning Number), and entering supplementary data not provided by an electronic chain of custody.

Screening constitutes an initial rapid evaluation for drug abuse. As Screening is a cost-effective method to dismiss drug presence in most samples, a positive result necessitates further confirmation to be validated in a court setting. Any samples identified as presumptively positive in Screening necessitate a follow-up confirmation.

Upon detecting a presumptive positive during the Screening process, additional hair is extracted from the initial sample for the Extraction phase. At this juncture, substances are isolated from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), which underscores the complexity of hair drug screenings.

Confirmation of any positive screening outcome is verified via GC/MS, GC/MS/MS, or LC/MS/MS. All samples labeled as presumptively positive are cleansed before confirmation if required. The end-to-end laboratory operations from Accessioning to Confirmation undergo scrutiny under the CAP (College of American Pathologists) Hair designation and conform to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair can reveal drug usage spanning up to 90 days, versus the shorter detection span of urine tests.
• Low susceptibility to tampering: Cheating a hair drug test is notably challenging, yielding more reliable outcomes.
• Tracks historical usage: It reflects drug consumption patterns over time, not solely recent activity.

Limitations:

• Incapable of indicating recent intake: Drugs generally require around 5-7 days post-use to become detectable in hair.
• Expense: Hair testing usually incurs higher costs than most other drug testing modalities.
• Result variability: Factors like hair color and personal differences in hair growth can influence the level of drug metabolites present in the hair.

Note: The term "hair follicle tests" commonly used actually refers to analysis of the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
