Hair Follicle Drug Testing - Hill City, KS

What it is, How it works

Hair analysis is recognized as an effective means for identifying drug and alcohol use. It captures a long-term record of alcohol and drug intake by embedding markers within the structure of the hair as it grows. When taken from near the scalp, hair can offer a detection period of up to three months for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is convenient.

A sample measuring 1.5 inches of around 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp provides 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, or tests that exceed 10 panels, 150mg is advisable. It's best to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair is an alternative. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is entered into a lab’s framework. This step ensures the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data input not covered by an electronic chain of custody.

Screening provides an initial, quick evaluation for substance abuse. Although it is an economical method to exclude drug use in most samples, a positive screen must be verified to be legally admissible. Any samples that return a presumptive positive result in Screening need a confirmatory test.

Should a sample be presumptively positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs in hair are processed at a lower concentration compared to other techniques (e.g., urine or oral fluid), which makes hair drug testing the most intricate method to execute.

Confirmation of any positive result from Screening occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab process from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a shorter detection span.
• Difficult to manipulate: Cheating on a hair drug test is extremely challenging, thereby enhancing accuracy.
• Historical information: Offers a timeline of drug use patterns over a duration, not just recent usage.

Limitations:

• Does not detect recent use: It generally takes 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug testing typically incurs greater costs than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although often labeled as "hair follicle tests", the analysis is performed on the hair strand itself, rather than the sub-scalp follicle.

Why Hair Follicle Testing Beats Urine Testing

In Hill City, KS, hair follicle testing clearly outshines 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.
