Hair Follicle Drug Testing - Federal, PA

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. The hair captures long-term substance use history by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can reveal alcohol and other drug usage up to roughly a 3-month period. The collection process is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for analysis and validation. For tests like EtG, add-ons, or over 10 panels, 150mg of the sample is optimal. The specimen should be weighed using a jeweler's scale. If scalp hair is inaccessible, an equivalent amount of body hair can be taken. Head hair pertains solely to scalp hair, whereas body hair encompasses all other types (such as facial and axillary).

Process Overview

The laboratory processing of a drug test result encompasses four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially processing a sample into the laboratory's system. This step includes confirming the sample's proper sealing and shipment, allocating it a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody.

Screening constitutes an initial rapid evaluation for abuse substances. While it is an economical method to exclude drug usage for the majority of samples, a positive screen demands verification to be court-admissible. Any samples with presumptive positives during Screening must undergo a secondary confirmation.

Should a sample show a presumptive positive during Screening, additional hair is retrieved from the original sample in preparation for Extraction. During this phase, drugs are isolated from hair in significantly lower concentrations than other techniques (e.g., urine or oral fluid), rendering hair drug screening uniquely challenging.

Any positive results from screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are washed before confirmation as necessary. The comprehensive lab process, from Accessioning to Confirmation, is assessed under CAP (College of American Pathologists) Hair designation and holds accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug examinations can trace drug use for as long as 90 days, which surpasses the shorter detection period of urine tests.
• Low likelihood of deception: Cheating a hair drug test is extremely challenging, enhancing the accuracy of results.
• Historical data provision: It demonstrates a usage pattern over time, rather than just recent use.

Limitations:

• Inability to pinpoint recent use: It generally takes 5-7 days before substances are detectable in the hair.
• Expense: Hair drug examinations typically carry a higher price than other testing methodologies.
• Result variations: Elements like hair color and individual hair growth differences can impact drug metabolite concentrations in the hair.

Note: Though commonly called "hair follicle tests", it is the hair strand and not the hair follicle beneath the scalp that gets examined.

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.
