Hair Follicle Drug Testing - Bohemia, NY

What it is, How it works

Hair testing is widely acknowledged as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive history of substance use by encasing biomarkers within the strands of the growing hair. When procured near the scalp, hair can reveal a detection range for substances, including alcohol, reaching up to nearly 3 months. Hair collection is straightforward, not easily tampered with, and convenient for transport.

Collecting a 1.5-inch hair sample of about 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is considered the optimal sample for both screening and confirmation. For testing involving EtG, additional panels, or those exceeding 10 panels, a quantity of 150mg is preferred. Utilizing a jeweler’s scale is recommended for weighing the specimen. If scalp hair is not accessible, an equivalent amount of body hair can be used. In discussions regarding head hair, it refers strictly to scalp hair. Body hair encompasses other varieties such as facial and underarm hair.

Process Overview

Laboratory processing of a drug test consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase of integrating a sample into the lab's workflow. This step covers the validation of proper sealing and shipping of the sample, the allocation of a unique LAN (Laboratory Accessioning Number), and completion of any outstanding data entry that is not already provided by an electronic chain of custody system.

Screening entails a swift preliminary analysis for potential drugs of abuse. Although Screening is a cost-efficient approach to eliminate drug usage in most cases, a positive screen must be validated to be court-admissible. Samples that display presumptive positive results in Screening require subsequent confirmation.

If the Screening phase yields a presumptive positive outcome, additional hair is extracted from the original specimen and readied for Extraction. This stage involves extracting drugs from hair at much lower concentrations compared to other techniques such as urine or oral fluid analysis, thus making hair drug screening one of the most complex methodologies to administer.

Confirmation of any positive screen is performed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Each presumptive positive sample undergoes washing before confirmation if required. The complete laboratory process from Accessioning to Confirmation is subject to review 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 tests identify drug consumption for up to 90 days, as opposed to urine tests which have a shorter detection timeframe.
• Challenging to deceive: Cheating a hair drug test is notably difficult, leading to more accurate results.
• Historical usage insights: It reveals a pattern of drug use over an extended period, not solely recent usage.

Limitations:

• Cannot identify recent use: Detectability of drugs in hair typically requires 5-7 days.
• Costly: Hair drug tests tend to be pricier compared to other drug testing alternatives.
• Result variability: Elements such as hair color and individual hair growth differences can impact drug metabolite concentrations in the hair.

Note: Although frequently termed as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When compared to traditional urine tests, hair follicle testing in Bohemia, NY, proves superior for several reasons. Notably, it offers enhanced detection accuracy for drug use, providing a more reliable overview of an individual's substance history.
