In Gray, Louisiana, Accredited Drug Testing offers extensive hair follicle drug testing services. If a hair-based drug or alcohol screen is needed, our specialization in hair testing ensures availability in cities nationwide. Generally, 1.5 to 2 inches of hair from the head or body is necessary. This test can detect drugs, alcohol/ETG, or be tailored for specific needs.
The use of hair follicle drug tests has been on the rise in recent years for drug screening. Employers, courts, and Substance Abuse experts now prefer hair drug testing over traditional urine tests. Employers with a zero-tolerance drug policy and courts often favor hair testing due to its longer detection window of up to 90 days, observed collection process, and resistance to tampering. Despite its strengths, urine tests remain the preferred method for detecting recent drug use within the last five days.

Hair analysis emerges as a significant resource in detecting drug and alcohol intake. Hair captures long-term consumption patterns of substances by embedding biomarkers within the hair strand fibers as they grow. Collected from near the scalp, hair can reveal drug and alcohol use within approximately a 3-month window. The collection of hair is straightforward, challenging to tamper with, and convenient for transport.
A sample consisting of 1.5 inches of roughly 200 hair strands (nearing the thickness of a #2 pencil) adjacent to the scalp equates to 100mg of hair, which is optimal for initial and confirmatory analysis. For EtG, additional screenings, or tests exceeding 10 panels, a 150mg sample is advised. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair may be procured. When referring to head hair, it specifically indicates scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The core stages involved in lab-based drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into a lab’s framework. This step involves ensuring the sample’s seal and shipment integrity, designating a random LAN (Laboratory Accessioning Number), and finalizing any requisite data entry not covered by an electronic chain of custody system.
Screening serves as a preliminary inspection for substance abuse. Although Screening is an economically efficient approach to exclude drug consumption for most samples, a positive result necessitates confirmation to be court-admissible. Samples with presumptive positive results from Screening mandate subsequent confirmation.
For samples that yield presumptively positive results during Screening, additional hair is extracted from the initial sample for further Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), affirming why hair drug screening ranks as the most intricate methodology.
Confirmation of any positive Screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if needed. The complete laboratory sequence, from Accessioning to Confirmation, is scrutinized as per the CAP (College of American Pathologists) Hair directive and accredited to ISO / IEC 17025 criteria.

Note: Although often dubbed "hair follicle tests", the evaluation focuses on the hair strand, omitting the follicle beneath the scalp.
