Hair Follicle Drug Testing - Hall Park, OK

What it is, How it works

Hair analysis is increasingly valued for its efficacy in identifying drug and alcohol consumption. Over time, hair embeds markers within its fibers, offering an extensive record of substance use. When sourced near the scalp, it can indicate alcohol and drug presence for roughly a three-month period. Hair samples are easy to collect, challenging to tamper with, and simple to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (roughly the size of a #2 pencil) nearest the scalp provides 100mg, the optimal amount for both screening and confirmation. For tests like EtG, additional testing, or assessments exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample on a jeweler's scale. If scalp hair isn't available, a similar quantity of body hair can be used. Note that 'head hair' specifically pertains to scalp hair, while 'body hair' encompasses all other types (e.g., facial, axillary).

Process Overview

The procedure for processing a drug test outcome in a lab encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase includes the initial incorporation of a sample into a lab’s system. This phase ensures the sample is appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not handled by electronic chain of custody processes.

The Screening phase conducts a preliminary check for substance abuse. Though Screening is an economical means to exclude drug presence in most samples, outcomes showing potential positivity must be validated for court eligibility. Any samples with presumptive positive results in Screening necessitate secondary verification.

Should a sample show presumptive positivity during Screening, additional hair is extracted from the initial specimen for the Extraction stage. Here, drugs are drawn from hair at diminished concentrations compared to other techniques (e.g., urine or oral fluid), which underscores the complexity of performing hair drug screening.

Every positive result from screening undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before Confirmation, as required. The entire lab course, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and the ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption up to 90 days prior, unlike urine tests, which have a shorter detection span.
• Hard to tamper with: Cheating a hair drug test is incredibly challenging, leading to more precise results.
• Offers historical insight: Hair drug tests display a pattern of drug use across time, not just recent intake.

Limitations:

• Unable to detect recent consumption: It requires about 5-7 days for drugs to manifest in hair samples.
• Expense: Generally, hair drug tests cost more than alternative drug testing methods.
• Result variations: Elements such as hair color and unique growth patterns can influence the concentration of drug metabolites within hair.

Note: Although commonly called "hair follicle tests", the analysis evaluates the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing is considerably superior to urine screening in Hall Park, OK. Its long detection window and resistance to manipulation provide a more accurate depiction of drug use over time. While urine tests may detect substances used recently, hair tests offer an in-depth view, making them a preferred choice for many stakeholders.

Extended Detection Window

In Hall Park, OK, hair follicle testing captures a longer history of drug use, up to 90 days. This expanded detection period allows employers to gain a deeper insight into an individual’s substance habits, crucial for making informed decisions regarding employment and ensuring a safe workplace.

Tamper-Resistant Testing Method

Hair follicle testing boasts a robust defense against tampering, a significant advantage in Hall Park, OK. Its methodology lessens the chance of altering results, offering reliability and confidence in the outcomes provided. This integrity is vital for both legal and professional scenarios requiring indisputable evidence.

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.
