Accredited Drug Testing offers comprehensive hair follicle drug screening in Richardson, Washington. If you're seeking a hair drug or alcohol test, we specialize in hair testing and boast testing facilities in every city across the nation capable of conducting such tests. Typically, 1.5 to 2 inches of hair from the crown or body is required. Hair tests are available for drug, alcohol/ETG, or other bespoke testing options.
In recent times, hair follicle drug tests have gained prominence as a preferred method for drug screening. Numerous employers, legal entities, and substance abuse experts now favor hair tests over traditional urine tests. Hair follicle tests are essential for zero-tolerance employers, the legal system, and those on probation. A significant advantage is the extended 90-day detection window, coupled with an observed collection process that is difficult to compromise. However, for detecting recent drug usage within five days, urine tests retain their accuracy.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other drug usage by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can offer approximately a 3-month window of detection for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil width) near the scalp will yield 100mg of hair, which is optimal for both screening and confirmation procedures. For EtG, additional tests, and those exceeding 10 panels, a specimen weighing 150mg is advisable. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is not present, an equivalent quantity of body hair may be gathered. References to head hair specifically mean scalp hair, while body hair includes other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for drug test analysis encompasses four essential phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing to be integrated into a lab's system. This involves confirming that the sample was adequately sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from an electronic chain of custody system.
Screening conducts a preliminary, swift evaluation for drugs of abuse. While Screening effectively eliminates drug usage for most samples, any positive results must undergo confirmation to be valid in legal contexts. Samples that yield presumptive positive results in Screening necessitate further confirmation.
If a sample returns a presumptive positive result in the Screening phase, additional hair is drawn from the initial sample to prepare it for Extraction. During Extraction, drugs are isolated from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex method to execute.
Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples are cleansed before confirmation if required. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the recognition to ISO / IEC 17025 standards.

Note: The commonly used term "hair follicle tests" actually pertains to an analysis of the hair strand itself, not the follicle beneath the scalp.

The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
