Accredited Drug Testing provides thorough hair follicle drug assessments in El Paso de Robles (Paso Robles), CA. If a hair drug or alcohol analysis is needed, Accredited Drug Testing excels in hair examinations, offering centers in every U.S. city for hair testing. A hair length of 1.5 to 2 inches on the head is necessary or body hair may work. Hair tests can assess drugs, alcohol/ETG, or other custom testing options.
Recently, drug testing methods increasingly include hair follicle drug tests. Many employers, courts, and substance abuse professionals prefer this over urine tests. Hair follicle drug tests are favored by zero-tolerance employers, courts, and probationers. The main advantage is a longer drug detection period, typically up to 90 days, through observed collection, making cheating nearly impossible. However, for drug use screening within the past 5 days, urine tests remain the most accurate.

The use of hair testing has increasingly become recognized as an effective means for identifying drug and alcohol consumption. Hair maintains a chronological record of alcohol and other substances by capturing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can offer a detection period for alcohol and drugs of up to roughly three months. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands, comparable to the width of a #2 pencil, nearest the scalp provides 100mg of hair, the optimal sample size for both screening and confirmation. For assessments involving EtG, supplementary tests, and/or those exceeding 10 panels, a 150mg specimen is advised. We suggest using a jeweler’s scale for specimen weighing. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. Reference to head hair implies scalp hair exclusively. Body hair encompasses all other hair varieties (facial, armpit, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into a laboratory’s system. This stage includes confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and executing any further data entry absent from an electronic chain of custody system.
Screening serves as an initial rapid assessment for drugs of abuse. While Screening is an economical method to negate drug use in most samples, a positive indication must be corroborated for legal admissibility. Any sample with a presumptive positive result in Screening necessitates subsequent confirmation.
If a sample is deemed presumptively positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), contributing to hair drug screening being the most challenging method to execute.
Confirmation of any positive screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed as necessary before confirmation. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Note: Although frequently termed as "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp
