Hair Follicle Drug Testing - Norco, LA

What it is, How it works

Utilizing hair examinations has emerged as an effective approach for identifying alcohol and drug consumption. Hair can capture a protracted record of drug and alcohol intake by encapsulating biomarkers within the expanding hair strand fibers. When gathered near the scalp, hair can offer close to a three-month detection timeframe for drugs and alcohol. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch section of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp produces 100mg of hair, representing the ideal sample for both screening and confirmation processes. For tests such as EtG, add-ons, or assessments exceeding 10 panels, 150mg of the specimen is advisable. It is suggested to weigh the specimen using a jeweler's scale. If head hair is not obtainable, an equivalent quantity of body hair can be used. When mentioning head hair, it pertains strictly to scalp hair, while body hair covers other types (facial, armpit, etc.).

Process Overview

The primary stages within the laboratory processing of a drug testing result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the preliminary processing of a sample into the lab's system. This process includes ensuring the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry not included in an electronic chain of custody system.

Screening denotes an initial swift inspection for drug misuse. Although Screening presents a cost-effective method to dismiss drug usage in most samples, a positive screen must be confirmed to stand in legal proceedings. Any screenings showing presumptive positivity necessitate secondary confirmation.

Should a sample show presumptive positivity during Screening, additional hair is extracted from the original specimen for Extraction preparation. This stage involves drug extraction from hair at notably lower concentration levels than alternative methodologies (such as urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.

Confirming any positive screening outcome carries out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples displaying presumptive positivity are washed before confirmation, as necessary. The entire laboratory procedure, from Accessioning through to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for a duration of up to 90 days, as opposed to urine tests which offer a shorter detection period.
• High resistance to deceit: Cheating a hair drug test proves challenging, boosting the accuracy of the results.
• Historical drug use data: Offers a pattern of drug use over time, rather than just recent usage.

Limitations:

• Inability to detect recent use: It requires around 5-7 days for drugs to become evident in hair.
• Cost: Hair drug tests typically cost more than alternative drug testing methods.
• Result variability: Elements like hair color and personal hair growth variations may influence drug metabolite concentrations in the hair.

Note: Although often labeled as "hair follicle tests," the test actually analyzes the hair strand and not the follicle beneath the scalp.
