Hair Follicle Drug Testing - Sharpe, KY

What it is, How it works

Hair examination has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug exposure by capturing markers in the fibers of the developing hair strand. Collected near the scalp, hair can reveal a detection period of up to around three months for alcohol and drugs. It's easy to gather, challenging to tamper with, and straightforward to transport.

A 1.5-inch section consisting of about 200 hair strands (comparable to the size of a #2 pencil) collected closest to the scalp yields 100mg of hair, which is the optimal sample size for screening and verifying. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. It's suggested to measure the specimen on a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair can be used. References to head hair specifically denote scalp hair. Body hair encompasses all additional hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes the following four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial processing of a specimen into a lab's system. This involves confirming the sample was appropriately sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening involves a preliminary rapid assessment for abused drugs. Although Screening is cost-efficient for ruling out drug usage in most specimens, a positive result requires confirmation for legal acceptability. Samples showing a presumptive positive result in Screening necessitate secondary verification.

For samples showing a presumptive positive in the Screening phase, more hair is extracted from the original sample and readied for Extraction. Here, drugs are withdrawn from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.

Confirmation of any positive screen outcome is done via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive are cleansed before confirmation when necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized according to the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can find drug usage for up to 90 days, unlike urine tests with a shorter detection span.
• Difficult to evade: Avoiding a hair drug test is quite challenging, making the results more reliable.
• Offers historical insights: It can indicate a drug use trend over time, not just recent consumption.

Limitations:

• Cannot indicate recent consumption: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Generally, hair drug tests are pricier than other drug testing approaches.
• Result variability: Aspects like hair color and individual hair growth differences might impact drug metabolite concentrations in hair.

Note: While sometimes called "hair follicle tests," the test itself analyzes the hair strand, not 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.
