Hair Follicle Drug Testing - University At Buffalo, NY

What it is, How it works

Hair testing has emerged as a formidable resource in identifying substance use of drugs and alcohol. A lengthy record of alcohol and drug usage is captured in the growing hair's fiber structure, as it locks in unique biomarkers. When hair is taken close to the scalp, it can reveal a usage history extending up to roughly three months for alcohol and drugs. The process of gathering hair is straightforward, tampering can be quite challenging, and transportation is hassle-free.

An optimal 1.5-inch segment of nearly 200 hair strands, akin in size to a #2 pencil and nearest to the scalp, will yield 100mg—the preferred amount for analysis and verification. If testing for EtG, additional requirements, or assessments beyond 10 panels, a 150mg sample is advised. It's advisable to determine the weight using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent mass of body hair is alternatively valid. It is important to clarify that head hair exclusively denotes hair on the scalp, while body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The four pivotal procedures in laboratory analysis for drug test results consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the foundational step where the sample enters a lab’s database. This phase confirms the sample’s proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and fills in any lacking information otherwise unsupported by an electronic chain of custody mechanism.

Screening entails an expedited evaluation for potential drug abuse. While Screening is a cost-efficient method to identify drug use absence in most specimens, a positive detection must be confirmed for legal admissibility. Samples yielding a presumptive positive in Screening necessitate another verification process.

If Screening suggests a positive, additional hair from the original sample is extracted for Extraction preparation. This phase allows retrieving drugs from hair at a minute concentration, distinguishing it from other methods such as urine or oral fluid, signifying hair drug analysis as the most intricate procedure to execute.

Any positive screening outcome is validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are washed before confirmation if required. The entire lab procedure, from Accessioning to Confirmation, is subject to review per both the CAP (College of American Pathologists) Hair criteria and the accreditation in compliance with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection timeframe: Hair drug assessments can identify drug consumption as far back as 90 days, whereas urine tests offer a shorter detection period.
• Cheating resistance: It is significantly challenging to falsify a hair drug assay, thus enhancing result accuracy.
• Produces historical insight: It offers consumption patterns over time rather than identifying only recent usage.

Limitations:

• Recent use detection: Drug presence in hair requires a duration of about 5-7 days before becoming detectable.
• Expense: Hair drug assessments generally incur higher costs than alternate methods.
• Variable results: Elements like hair color and personal hair growth differences can skew drug metabolite concentrations in hair.

Note: Commonly labeled as "hair follicle tests", this test analyzes the hair strand, rather than the follicle underlying the scalp.

Why Hair Follicle Testing Beats Urine Testing

In University at Buffalo, NY, hair follicle tests outperform traditional urine tests in several aspects. One major advantage is the extended detection window, which provides a more comprehensive history of drug use, unlike the shorter detection period of urine tests.
