Hair Follicle Drug Testing - Crescent, WI

What it is, How it works

Hair testing has emerged as an effective approach for identifying the use of drugs and alcohol. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the strands of developing hair. When hair is gathered near the scalp, it can reflect a drug and alcohol detection timeline of up to three months approximately. The process of collecting hair is straightforward, relatively resistant to tampering, and easily shipped.

A 1.5-inch segment of around 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation. When testing for EtG, additional tests, and/or more than 10 panels, 150mg of the sample is advisable. It is suggested to use a jeweler’s scale for weighing the sample. In the absence of scalp hair, a similar quantity of body hair may be used. When discussing head hair, we refer exclusively to scalp hair. Body hair includes all other hair forms (facial, axillary, etc.).

Process Overview

The four core processes involved in a laboratory's drug test analysis are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial processing into a lab's system. The steps include ensuring the sample was appropriately sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and conducting any additional data input not included by an electronic chain of custody method.

Screening constitutes an initial rapid drug of abuse assessment. Although Screening is an economical technique to eliminate drug usage for the majority of samples, a non-negative screen needs confirmation to be legally valid. Samples shown to be provisionally positive within Screening necessitate a further confirmation process.

When a sample is indicated as provisionally positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are isolated from hair at considerably reduced concentrations compared to alternative methods (for instance, urine or saliva), making hair drug screening a notably challenging technique to administer.

Confirming any non-negative screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing prior to confirmation as required. The whole lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for as long as 90 days, as opposed to urine tests which offer a shorter detection duration.
• Challenging to deceive: Hair drug tests are hard to cheat on, ensuring more precise outcomes.
• Yields historical insights: It reveals a trend of drug use over time, not merely recent consumption.

Limitations:

• Unable to detect recent use: It typically takes 5-7 days for drugs to appear in hair analysis.
• Expense: Hair drug tests often cost more than alternative drug testing approaches.
• Result variability: Elements such as hair color and individual hair growth disparities can impact drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the assessment itself focuses on the hair strand rather than the follicle beneath the scalp.
