Hair Follicle Drug Testing - Fisher, LA

What it is, How it works

Hair testing has gained prominence as an effective measure for detecting drug and alcohol consumption. Hair acts as a repository for drug and alcohol history, capturing biomarkers within the fibers of the hair strand as it grows. When taken near the scalp, hair can reflect usage patterns up to roughly a 3-month duration for alcohol and other drugs. Collecting hair is uncomplicated, relatively hard to tamper with, and convenient to mail.

A 1.5-inch segment comprising about 200 hairs (comparable to the thickness of a #2 pencil) close to the scalp yields 100mg of hair, forming the perfect sample for analysis and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample with a jeweler's scale. If no scalp hair is present, a similar quantity of body hair may be obtained. When mentioning head hair, we mean only scalp hair. Body hair encompasses all other variants (facial, axillary, etc.).

Process Overview

The four primary phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary intake of a sample into a laboratory's framework. This process ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input not furnished by an electronic chain of custody system.

Screening consists of an initial expedient examination for drugs of abuse. While Screening serves as a cost-efficient method to discount drug use for most samples, a positive outcome necessitates confirmation to stand in court. Any samples tentatively positive in Screening mandate further verification.

Should a sample show positive indicators during Screening, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are derived from hair at significantly diluted concentrations compared to alternative methods (e.g., urine or oral fluid), underscoring why hair drug screening presents more complexities.

Confirmation of any positive in the screening phase is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as required. The entire laboratory routine, from Accessioning to Confirmation, is conducted under both the CAP (College of American Pathologists) Hair designation and certified to ISO/IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, in contrast to urine tests with a shorter detection timeframe.
• Challenging to manipulate: It's exceedingly challenging to alter a hair drug test, rendering the outcomes more reliable.
• Offers past data: It supplies a timeline of drug use over an extended timeframe, not solely recent consumption.

Limitations:

• Inability to detect immediate use: Detection of drugs in hair requires about 5-7 days post-consumption.
• Expense: Hair drug tests typically carry a greater cost than other drug testing techniques.
• Result variations: Aspects such as hair color and personal differences in hair growth can influence the drug metabolite concentrations within hair.

Note: Although commonly known as "hair follicle tests", the evaluation itself regards the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Fisher, LA surpasses urine tests by offering superior detection. While urine tests provide current usage detection, hair tests reveal long-term patterns, improving assessment reliability.
