Accredited Drug Testing provides comprehensive hair follicle drug evaluations in Woodbridge, Virginia. For those in need of a hair drug or alcohol assessment, we excel in hair testing and have centers nationwide equipped for this analysis. Generally, 1.5 to 2 inches of hair from the head or body is required. Hair testing can screen for drugs, alcohol/ETG, and other tailored testing needs.
Recently, the preference for drug screening often includes hair follicle analysis. Many employers, judicial bodies, and substance abuse professionals now favor hair tests over urine tests. This method is crucial for zero-tolerance environments, courts, and probation monitoring due to its extended detection period of up to 90 days, conducted under supervision, making it hard to falsify. Yet, for detecting recent drug use within 5 days, urine tests remain the most precise.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair examinations are now recognized as a formidable method for uncovering drug and alcohol consumption. Hair encapsulates a history of such substances by securing biomarkers within its fibers as it grows. Collected from near the scalp, hair samples can offer up to a 3-month detection window for alcohol as well as other drugs. Hair collection is straightforward, moderately challenging to tamper with, and easy to transport.
A 1.5-inch specimen consisting of roughly 200 strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the optimal amount for assessments and confirmations. For EtG tests, additional testing, or panels over ten, a 150mg specimen is advised. We propose using a jeweler’s scale for measuring the specimen. When scalp hair is unavailable, a comparable volume of body hair is suitable. By head hair, we mean scalp hair alone. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The chief stages of processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of introducing a sample into the laboratory’s system. This process includes confirming that the sample was sealed and transported correctly, granting a random LAN (Laboratory Accessioning Number), and performing any additional data input absent from an electronic chain of custody system.
Screening involves a preliminary evaluation for drugs of abuse. Although Screening is an economical method for excluding drug use in most samples, a positive result requires confirmation to be valid in a legal context. Any sample that is presumptively positive during Screening necessitates further confirmation.
Should a sample appear presumptively positive in the Screening phase, more hair is extracted from the original sample for Preparation. Extraction retrieves drugs from hair at a lower concentration than other methods (ex. urine or saliva), which renders hair drug testing the most complex methodology.
Confirmatory testing of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing positive are cleansed before confirmation if deemed necessary. The entire lab process from Accessioning to Confirmation undergoes a review aligned with both the CAP (College of American Pathologists) Hair categorization and ISO / IEC 17025 standard accreditation.
