Hair Follicle Drug Testing - Shelburn, LA

What it is, How it works

Hair testing has emerged as a formidable method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and other drugs by embedding biomarkers in the fibers of the growing hair strand. When collected near the scalp, hair can offer close to a 3-month detection window for alcohol and other substances. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch sample consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is advised. We suggest weighing the specimen with a jeweler’s scale. Should scalp hair be absent, an equivalent quantity of body hair can be gathered. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a lab’s system. This involves ensuring the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data input not supplied by an electronic custody chain system.

Screening entails a preliminary swift examination for substances of abuse. Although Screening is an economical method to exclude drug usage on most samples, a positive screen necessitates confirmation to be court-admissible. Any samples presumed positive in Screening require a supplementary confirmation.

If a sample is deemed presumptively positive in the Screening phase, further hair is extracted from the original specimen and readied for Extraction. Here, drugs are removed from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most intricate methodology to execute.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized 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 have a shorter detection timeline.
• Resistance to tampering: It is extremely challenging to deceive a hair drug test, enhancing result accuracy.
• Offers historical insights: It can reveal a drug use pattern over time, not merely recent consumption.

Limitations:

• Inability to detect recent usage: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically more costly than alternative drug testing techniques.
• Result variability: Variables such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite being commonly referred to as "hair follicle tests", the examination itself assesses the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Shelburn, LA can be understood by comparing benefits. Hair tests offer superior detection accuracy and reliability over traditional urine samples.
