Accredited Drug Testing provides comprehensive hair follicle drug testing services in Tappahannock, Virginia. Whether you require a hair-based drug or alcohol screening, Accredited Drug Testing excels in these tests, with facilities across all cities nationwide ready to perform them. A length of 1.5 to 2 inches of hair from the crown or body can generally be tested. Hair analyses can detect drugs, alcohol/ETG, or other custom options.
Recently, more organizations have turned to hair follicle drug testing methods. Employers, judicial systems, and substance abuse professionals now prefer hair tests over traditional urine tests. This switch caters to zero-tolerance drug policies at workplaces, courts, and for individuals on probation. Hair tests offer longer drug detection—up to 90 days, are conducted under observation, and are hard to tamper with. For screening recent drug use within the last five days, urine tests remain highly accurate.

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. It chronicles a prolonged history of substance intake by encasing biomarkers within the fibers of the hair as it grows. When the sample is taken near the scalp, it offers a detection timeframe of up to around 3 months for alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch section, consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) from near the scalp, yields 100mg—an optimal quantity for both initial tests and confirmatory analysis. For EtG, additional substances, and tests beyond 10 panels, 150mg of hair is advisable. Using a jeweler’s scale is recommended to measure the hair's weight. If scalp hair is not available, an equivalent quantity of body hair can be used. When mentioning head hair, only the scalp hair is implied. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The process of laboratory examination of a drug test outcome involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is integrated into the lab’s system. This step ensures the sample is sealed and sent properly, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not handled by an electronic chain of custody system.
Screening involves a preliminary evaluation for substances of abuse. Though Screening is a budget-friendly strategy to eliminate drug use in most samples, a positive result requires validation for legal acceptability. Samples with likely positive results in Screening need further confirmation.
If a specimen shows presumptive positives during Screening, more hair is extracted from the initial sample for the Extraction phase. At this point, drugs are isolated in the hair at considerably lower concentrations than in alternative methods (e.g., urine or oral samples), demonstrating why hair drug screening is the most complex method to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo washing if necessary before confirmation. The whole lab procedure, from Accessioning to Confirmation, complies with CAP (College of American Pathologists) Hair standards and meets ISO / IEC 17025 accreditation criteria.
