Hair Follicle Drug Testing - Wynona, OK

What it is, How it works

Hair analysis is increasingly regarded as a robust method for identifying drug and alcohol consumption. The fibers of a growing hair strand capture biomarkers that can reveal a user’s long-term history with these substances. By collecting hair samples near the scalp, one can achieve a detection timeframe of about three months for both alcohol and drugs. This method is straightforward in collection, somewhat resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches and comprising around 200 hair strands (approximately the thickness of a #2 pencil) closely cropped to the scalp yields 100mg, which is optimal for both screening and confirmation tests. For comprehensive tests such as EtG, additional panels exceeding ten, 150mg is preferred. It's advisable to determine the specimen’s weight using a jeweler’s scale. Should scalp hair be inadequate, an equivalent amount of body hair is acceptable. The term head hair pertains specifically to scalp hair, whereas body hair encompasses all other varieties (like facial and underarm hair).

Process Overview

The drug test laboratory processing involves four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial phase where a sample is integrated into a laboratory system. This involves ensuring the sample was appropriately sealed and dispatched, assigning it a unique LAN (Laboratory Accessioning Number), and executing additional data entry when an electronic chain of custody system hasn’t provided all necessary details.

Screening is a preliminary assessment for substances of abuse. Though Screening is a cost-efficient approach for excluding drug use in most samples, a positive outcome mandates further confirmation for legal validity. Samples flagged as presumptively positive during Screening require an additional verification step.

During Extraction, if a sample shows probable positivity at the Screening stage, extra hair is taken from the initial sample and readied for extraction. Hair drug screening extracts drugs from hair at significantly lower concentrations than other methods such as urine or oral fluid, which makes it a more challenging technique to conduct.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive undergo a washing process pre-confirmation, if necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized in accordance with both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair drug testing is capable of identifying drug use for as many as 90 days, whereas urine testing offers a shorter detection period.
• Challenging to manipulate: Manipulating hair drug test results is highly challenging, thus enhancing result accuracy.
• Historical trend data: It provides insight into a user’s drug consumption pattern over time, not just recent usage.

Limitations:

• Lacks detection of immediate use: Drugs require about 5-7 days to become noticeable in hair.
• Higher expense: Hair drug tests entail a greater cost compared to other testing methods.
• Result variations: Differences in hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Commonly called "hair follicle tests", the analysis is on the hair strand itself rather than the follicle beneath 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.
