Hair Follicle Drug Testing - Rio Rico, AZ

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug use by embedding biomarkers within the fibers of the developing hair shaft. When procured near the scalp, hair can reveal a detection duration of up to roughly three months for alcohol and drugs. Hair is uncomplicated to gather, somewhat resistant to tampering, and simple to transport.

A 1.5-inch portion encompassing around 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for screening and verification. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg of the hair is advised. Using a jeweler’s scale for the specimen weighing is suggested. If head hair is absent, a comparable quantity of body hair can be used. By head hair, we mean scalp hair only. Body hair refers to all other types such as facial, axillary, etc.

Process Overview

The quartet of critical steps in the laboratory processing of a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the first step of incorporating a sample into the laboratory’s system. This process encompasses confirming the sample was correctly sealed and dispatched, allotting a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not included in an electronic chain of custody system.

Screening entails an initial brief evaluation for drugs of abuse. Screening is an economical method for eliminating drug use in the majority of cases. However, a positive screen necessitates confirmation to stand in court. Specimens presumed positive from Screening do necessitate a secondary confirmation.

If a specimen is presumptively positive during Screening, additional hair is extracted from the initial batch to prepare for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), which explains why hair drug screening ranks among the most challenging methodologies.

Verification of any affirmative screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a wash before final confirmation if necessary. The end-to-end lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug usage for up to 90 days, unlike urine evaluations with a smaller detection period.
• Hard to deceive: Hair drug evaluations are challenging to deceive, augmenting result accuracy.
• Offers historical information: It presents a pattern of drug use across time, beyond just immediate use.

Limitations:

• Inability to identify recent use: Drugs take around 5-7 days to be noticeable in hair.
• Expense: Hair drug tests often cost more than other drug testing forms.
• Result variations: Factors like hair color and person-specific hair growth can influence drug metabolite concentration in hair.

Note: Although commonly termed as "hair follicle tests", the examination itself evaluates the hair strand and not the hair follicle 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.
