Hair Follicle Drug Testing - Fairfield, OK

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol consumption. It offers a comprehensive history of drugs by capturing biomarkers within the fiber strands of hair. When sampled near the scalp, hair can reveal up to a 3-month period of drug and alcohol usage. The process of collecting hair is straightforward, hard to tamper with, and simple to transport.

A segment measuring 1.5 inches with around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, which is the preferred amount for both screening and confirmation processes. For EtG, supplementary tests, and panels exceeding 10, a specimen weight of 150mg is suggested. It's advisable to use a jeweler’s scale to measure the weight of the sample. In instances where scalp hair is not available, a similar quantity of body hair can be gathered. When mentioning head hair, it specifically implies scalp hair. In contrast, body hair includes various types, such as facial and axillary hair.

Process Overview

The laboratory process of a drug test result involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample is integrated into the laboratory's system. This step ensures that the sample was appropriately sealed and dispatched, assigns it a distinct LAN (Laboratory Accessioning Number), and carries out any supplementary data recording not already covered by an electronic chain of custody.

Screening offers an initial assessment for substances of abuse. Although Screening efficiently eliminates drug use possibility in the majority of samples, a positive result must be confirmed to hold in legal settings. Any samples suspected to be positive during Screening warrant an additional confirmation procedure.

If a sample indicates potential drug presence during Screening, additional hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than seen in other testing methods (such as urine or oral fluid), making hair drug testing the most intricate method.

Validation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation undergoes scrutiny following both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have a detection span of up to 90 days, unlike urine tests with shorter spans.
• Resistance to fraud: Cheating on a hair drug test is notably challenging, ensuring more reliable outcomes.
• Records of past usage: It provides a pattern showing drug use over time, rather than just a recent use indication.

Limitations:

• Inability to detect recent usage: Drugs only become detectable in hair about 5-7 days post-consumption.
• Cost implications: Generally, hair drug tests cost more than other drug testing approaches.
• Result variability: Elements such as hair color and individual growth rates can impact the drug metabolite concentration in hair.

Note: Though termed as "hair follicle tests," these tests actually examine the hair strand, not the follicle residing 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.
