Hair Follicle Drug Testing - Lorena, TX

What it is, How it works

Hair analysis has emerged as an effective instrument for detecting drug and alcohol consumption. Hair captures a prolonged record of substance use by encapsulating biomarkers within the hair strand as it grows. When gathered near the scalp, hair can showcase a detection span of up to around 3 months for drugs and alcohol. This type of testing is straightforward in collection, challenging to tamper with, and convenient to transport.

An ideal screening involves a 1.5-inch sample (approximately the thickness of a #2 pencil) of approximately 200 hair strands nearest to the scalp, yielding 100mg of hair. For EtG, add-ons, and tests exceeding 10 panels, a specimen amount of 150mg is preferred. It is advisable to use a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent quantity of body hair can be utilized. We specify that head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four crucial steps in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is first incorporated into a laboratory’s system. This procedure confirms the sample was correctly sealed and dispatched, generates a random Laboratory Accessioning Number (LAN), and finalizes any extra data entries not captured by an electronic chain of custody system.

Screening involves a swift preliminary assessment for drugs of abuse. While Screening is cost-efficient for excluding drug use in most samples, a screen yielding a positive result necessitates confirmation for court admissibility. Samples with a presumptive positive outcome in Screening require additional verification.

Should a sample show a presumptive positive result in the Screening phase, further hair is extracted from the initial specimen for the Extraction process. Drugs are pulled from the hair at much reduced concentrations in contrast to other methodologies (such as urine or oral fluid), making hair drug testing the most complex methodology to execute.

Confirmation of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Each presumptive positive sample is washed as required before confirmation. The comprehensive laboratory process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) hair classification and accredited per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage for as long as 90 days, unlike urine tests which offer a shorter detection range.
• Challenge to manipulate: Manipulating a hair drug test is exceedingly difficult, making the results highly reliable.
• Historical insight: It provides insight into drug usage patterns over an extended period, not merely recent use.

Limitations:

• Inability to detect recent usage: It typically takes 5-7 days for drugs to be discernable in hair.
• Expense: Hair drug tests generally entail higher costs compared to other testing techniques.
• Result variability: Elements such as hair color and individual hair growth changes can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", this method assesses the hair strand, not the follicle beneath the scalp.
