Hair Follicle Drug Testing - Granite, MD

What it is, How it works

Hair testing is viewed as an effective method for uncovering drug and alcohol consumption. Hair offers a long-term record of alcohol and drug intake by embedding biomarkers within the strands of hair as they grow. When gathered from close to the scalp, hair can reveal drug and alcohol use for up to approximately three months. The collection process is straightforward, challenging to tamper with, and simple to send off.

A hair sample measuring 1.5 inches and comprising about 200 strands (similar in size to a #2 pencil) from the scalp will yield 100mg, which is optimal for screening and confirmation. For EtG, additional tests, or panels over 10, a 150mg sample is ideal. It is advisable to weigh the sample with a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair may also be gathered. When mentioning head hair, this purely refers to scalp hair. Body hair refers to all other types (facial, axillary, etc.).

Process Overview

The key steps in laboratory processing for a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a specimen within a laboratory's system. This entails confirming the sample's secure sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and ensuring completion of any additional data processing absent from an electronic chain of custody.

Screening involves an initial rapid check for substances of abuse. While it is a cost-efficient method to dismiss drug usage in most specimens, a positive screening necessitates confirmation to be legally acceptable. Any presumptively positive specimens in Screening necessitate secondary verification.

Should a specimen yield a presumptively positive result during Screening, additional hair is extracted from the original sample for Extraction. This phase involves retrieving drugs from hair at a notably lower concentration than other methods (e.g., urine or oral fluid), rendering hair drug screening a more complex process.

Verification of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive specimens undergo washing before confirmation as needed. The laboratory process from Accessioning to Confirmation is rigorously reviewed, adhering to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests trace drug use for up to 90 days, as opposed to urine tests with shorter detection periods.
• Hard to manipulate: Hair drug tests are difficult to cheat, ensuring more credible results.
• Historical insight: It reveals a pattern of drug use over time, not merely recent instances of use.

Limitations:

• Lacks immediate detection: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variations: Hair color and personal hair growth differences can alter metabolite concentration in hair.

Note: The so-called "hair follicle tests" sample the hair strand rather than the underlying hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Granite, MD is clear<. While urine tests are more common, they lack the long detection window of hair tests. Hair analysis can trace drug intake over months, offering a complete substance history that urine analysis cannot match.

Another advantage of hair testing is its reliability; it is incredibly difficult to tamper with or manipulate a hair test as compared to a urine test, ensuring valid results.

Extended Detection Window

Due to their ability to detect drug use over longer periods, hair follicle tests offer incredibly valuable insights. In Granite, MD, businesses benefit from an impressive 90-day window that provides a detailed view of an individual's past substance habits.

This extended detection period is critical for employers looking to establish a thorough understanding of an applicant's or employee's background, thereby aiding in informed decision-making.

Tamper-Resistant Testing Method

One of the key features of hair follicle tests is their resistance to tampering. In Granite, MD, sample adulteration risk is minimal, ensuring the reliability of results. Unlike other methods, hair samples provide a solid foundation for accurate testing.

This reliability in results gives peace of mind to employers, knowing that the findings are trustworthy and not subject to manipulation.

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.
