Hair Follicle Drug Testing - Potter, AR

What it is, How it works

Hair analysis has emerged as a crucial method for detecting substance and alcohol consumption. Hair captures long-term indicators of substances and alcohol by embedding biomarkers within the structure of the growing hair strand. When gathered near the scalp, it offers an approximate 3-month detection timeframe for substances and alcohol. The process of collecting hair is straightforward, relatively hard to tamper with, and effortless to transport.

A sample of 1.5 inches consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for evaluation and confirmation. For EtG, additional tests, and/or evaluations exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair cannot be collected, an equivalent amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair, whereas body hair encompasses other types of hair (face, underarm, etc.).

Process Overview

There are four primary steps in the lab examination process of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the early stage of integrating a sample into a lab’s system. This process includes ensuring the sample was properly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and completing any further data input not covered by an electronic chain of custody system.

Screening is the preliminary assessment for drugs of misuse. Although Screening serves as a cost-efficient method to dismiss drug consumption for most samples, a positive result in Screening necessitates confirmation to be valid in legal proceedings. Samples testing presumptively positive in Screening require a secondary validation.

If a sample results in presumptive positivity during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. At this stage, substances are removed from hair at a much lower concentration compared to other methodologies (such as urine or oral fluid), making hair drug analysis a challenging method to execute.

Confirmation of any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positives are cleansed before confirmation as appropriate. The complete process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection timeframe: Hair drug evaluations can detect drug use up to 90 days, in contrast with urine tests which have a more limited detection window.
• Challenging to deceive: Cheating a hair drug analysis is quite challenging, enhancing the accuracy of the results.
• Offers historical insight: It provides an overview of substance use over time, not solely recent usage.

Limitations:

• Inability to detect recent consumption: It takes roughly 5-7 days for substances to become traceable in hair.
• Expense: Hair drug evaluations are usually pricier compared to other drug testing techniques.
• Results may vary: Elements like hair color and individual differences in hair growth can influence the concentration of substance metabolites in the hair.

Note: Although frequently termed as "hair follicle tests", the actual test analyzes the hair strand and not the follicle beneath the scalp.
