Hair Follicle Drug Testing - Alexander, WV

What it is, How it works

Hair analysis has emerged as an influential method for identifying drug and alcohol consumption. The hair can offer an extensive timeline of substance use by encapsulating biomarkers within the strands as they grow. When obtained from near the scalp, hair can yield a detection window of up to three months for alcohol and other substances. Obtaining hair samples is uncomplicated, relatively hard to tamper with, and straightforward to send.

A 1.5-inch hair sample (approximately the thickness of a #2 pencil) containing about 200 strands close to the scalp produces 100mg, the perfect amount for both screening and confirmation tests. For EtG, supplementary tests, or tests exceeding 10 panels, a sample size of 150mg is advised. Utilizing a jeweler’s scale for weighing the sample is recommended. In the absence of scalp hair, an equivalent quantity of body hair might be gathered. The term head hair pertains exclusively to scalp hair, while body hair includes other types such as facial or axillary hair.

Process Overview

The four essential phases in the lab processing of drug test results encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the preliminary handling of a sample into the lab's system. This step verifies that the sample has been sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry lacking from the electronic chain of custody system.

Screening entails an initial rapid test for illicit substances. Although Screening is an economical strategy to exclude substance usage in most samples, a positive result in screening must be validated for legal acceptability. Thus, any sample preliminarily positive in Screening mandates further verification.

If Screening indicates a presumptive positive, more hair is extracted from the original sample for the Extraction phase. This involves extracting drugs from hair in much lower concentrations compared to other methods (such as urine or oral fluid), highlighting hair drug screening as the most sophisticated methodology.

Confirmation of any positively screened result is performed with GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all samples showing presumptive positivity undergo washing when required. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use up to 90 days prior, unlike urine tests which have a more limited detection window.
• Challenging to falsify: Cheating a hair drug test is significantly difficult, which enhances the result's reliability.
• Tracks usage pattern: It supplies a usage pattern over a timeframe, instead of just identifying recent use.

Limitations:

• Incapable of recognizing recent usage: Drugs take about 5-7 days to become detectable in hair.
• Expensiveness: Typically, hair drug tests incur higher costs compared to alternative testing methods.
• Result variability: Variations in factors like hair color and individual hair growth rates can influence the levels of drug metabolites detectable in hair strands.

Note: Commonly termed "hair follicle tests," these assessments evaluate the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing outshines urine testing in Alexander, WV. One significant advantage is the prolonged detection window, offering a more comprehensive review of an individual’s drug history. Unlike urine tests, hair assessments remain effective against evasion attempts, providing employers with trustworthy outcomes.
