Hair Follicle Drug Testing - Bexar, AR

What it is, How it works

Hair analysis has emerged as an effective method for identifying substance and alcohol consumption. Hair offers a prolonged history of alcohol and other drugs by capturing biomarkers within the fibers of the maturing hair. When taken near the scalp, hair can reveal up to roughly a 90-day exposure period for alcohol and other substances. Hair is effortless to obtain, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the girth of a #2 pencil) nearest to the scalp will yield 100mg of hair, the preferred quantity for analysis and verification. For EtG, supplementary options, and/or screenings exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the sample. If scalp hair is not accessible, an equivalent quantity of body hair may be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four critical stages in the laboratory evaluation of a substance test outcome comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into the lab's framework. This involves ensuring the sample was properly sealed and dispatched, designating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not covered by an electronic custody tracking system.

Screening provides a preliminary rapid assay for substance abuse. Although Screening is an economical method to exclude substance consumption in most specimens, a positive screen necessitates confirmation to be legally acceptable. Any specimens that show presumptive positivity in Screening necessitate a subsequent verification.

If a specimen shows a presumptive positive during the Screening phase, additional hair is retrieved from the original sample and readied for Extraction. In this phase, substances are isolated from hair at a significantly lower concentration than with other techniques (such as urine or oral fluid), which is why hair substance analysis is the most challenging technique to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation is analyzed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can sense substance use for up to 90 days, in contrast to urine analyses that have a much shorter detection period.
• Hard to falsify: It is quite challenging to falsify a hair drug test, ensuring more precise results.
• Offers past data: It can reveal a timeline of substance use over a span of time, rather than just recent usage.

Limitations:

• Incapable of identifying recent consumption: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug screenings are often pricier compared to other substance testing techniques.
• Result variations: Elements like hair color and individual differences in hair growth can impact the level of drug metabolites in the hair.

Note: Although frequently termed "hair follicle tests", the examination itself evaluates the hair strand and not the follicle beneath the scalp.
