Hair Follicle Drug Testing - Port Ashton, AK

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol intake. Hair captures biomarkers within the strands as it grows, offering a lengthy history of substance use. Collected close to the scalp, hair can reveal up to a three-month detection period for alcohol and drugs. It is straightforward to collect, challenging to alter, and convenient to transport.

A sample of 1.5 inches consisting of roughly 200 hair strands (roughly the thickness of a #2 pencil) near the scalp provides 100mg, which is the preferable quantity for screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. In cases where scalp hair is absent, a comparable amount of body hair may be used. "Head hair" specifically refers to scalp hair, while "body hair" covers all other types (e.g., facial, axillary).

Process Overview

The key stages in a drug test’s laboratory processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial intake of a sample into the lab’s system. It involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not managed by an electronic chain of custody system.

Screening is a preliminary test for substance abuse. While it is a cost-efficient method to eliminate drug use across most samples, a positive screen must be verified to stand in court. Presumptive positive samples identified in Screening need a further confirmation.

For samples showing presumptive positives in the Screening phase, additional hair is extracted from the specimen for the Extraction process. This phase involves extracting substances from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug testing particularly challenging.

Confirmation of any positive screen results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use up to 90 days, compared to urine tests that have a shorter detection period.
• Hard to manipulate: It is quite challenging to tamper with hair drug tests, which enhances result accuracy.
• Offers an historical perspective: It showcases a pattern of drug use over time, not just recent use.

Limitations:

• Incapable of spotting recent use: It takes about 5-7 days for substances to appear in hair.
• Expense: Hair drug tests typically cost more than other drug testing approaches.
• Result variations: Aspects like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Despite the common term "hair follicle tests", the actual analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
