Hair Follicle Drug Testing - Saint Benedict, LA

What it is, How it works

Hair testing has established itself as a potent method for identifying alcohol and drug consumption. The strands of hair hold a prolonged record of drug and alcohol use by ensnaring biomarkers within the fibers during growth. Hair collected near the scalp can offer an alcohol and drug detection timeline of up to around three months. Collection of hair is straightforward, relatively hard to tamper with, and convenient for transportation.

A sample measuring 1.5 inches of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation stages. For EtG, supplementary tests, or tests exceeding 10 panels, a 150mg specimen is advised. It’s suggested to use a jeweler's scale to weigh the specimen. If scalp hair isn’t available, an equivalent quantity of body hair might be used. Head hair refers specifically to scalp hair. Other body hair encompasses all additional hair types, such as facial and axillary hair.

Process Overview

The instrumental phases in processing a drug test result in a lab encompass Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially entered into a laboratory's system. This phase includes checking proper sealing and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and completing additional data entry tasks absent from an electronic chain of custody system.

The Screening stage is a preliminary and swift appraisal for abusive drugs. While it offers an economical approach to exclude drug usage in many samples, any positive result necessitates confirmation for legal admissibility. Samples with presumptive positive outcomes at Screening must undergo a secondary confirmation.

For samples with presumptive positivity in Screening, additional hair is extracted from the specimen and prepped for Extraction. During this stage, drugs are removed from hair at a significantly lower concentration in comparison to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging technique to execute.

Confirmation of positive screening outcomes undergoes GC/MS, GC/MS/MS, or LC/MS/MS testing. All samples showing presumptive positivity are cleansed before confirmation if necessary. The complete lab process from Accessioning through Confirmation is inspected under the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug consumption for up to 90 days, unlike urine tests which offer a short detection span.
• Hard to deceive: Cheating on a hair drug test proves quite challenging, ensuring more precise results.
• Provides longitudinal data: It can show a historical pattern of drug use over time, not only recent use.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair roughly 5-7 days after use.
• Expense: Generally, hair drug tests cost more than alternative methods.
• Variability in results: Drug metabolite concentrations can vary due to differences in hair color and individual hair growth rates.

Note: The term "hair follicle tests" is often a misnomer; the test examines the hair strand and not the follicle beneath the scalp.
