Accredited Drug Testing offers comprehensive hair follicle drug testing services in Bristow, Virginia. For those in need of hair drug or alcohol tests, Accredited Drug Testing specializes in hair testing, with centers available nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head or body are required. Hair tests can detect drugs, alcohol/ETG, or be adapted for specific needs.
Recently, drug testing methods have increasingly favored hair follicle tests. Many employers, courts, and substance abuse professionals prefer hair tests over traditional urine tests. Zero-tolerance employers, courts, and individuals on probation commonly use hair follicle drug tests. The key advantage is the longer detection window, up to 90 days, with observed collection, making it difficult to tamper with. For detecting recent drug use within five days, urine tests remain the most precise.

Recognized for its effectiveness, hair testing is a significant method for identifying drug and alcohol consumption. Hair retains a long-term record of substances by capturing biomarkers within the fibers of growing hair strands. Sampling hair near the scalp offers an approximately 3-month detection period for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and easy to mail.
A 1.5-inch section of around 200 hair strands (resembling the thickness of a #2 pencil) nearest to the scalp constitutes a 100mg hair sample, optimal for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is preferred. We advise utilizing a jeweler’s scale to measure the hair sample. If scalp hair is unavailable, a comparable quantity of body hair may suffice. When we mention head hair, we mean scalp hair exclusively. Body hair refers to all other types of hair (e.g., facial, axillary).
Process Overview
The laboratory analysis of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample is integrated into the laboratory system, ensuring it was sealed and transported correctly, assigning a random Laboratory Accessioning Number (LAN), and completing any additional data entry not supplied by the electronic chain of custody system.
Screening entails a preliminary examination for drug presence. Although Screening is a cost-effective means to dismiss drug usage in most samples, a positive screen requires confirmation to be valid in a legal context. Any samples marked as presumptively positive during Screening must undergo a second confirmation.
When a sample is presumptively positive in Screening, additional hair is extracted from the original sample for the Extraction phase. This involves extracting drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluids), which makes hair drug screening the most complex method to execute.
The confirmation of any positive screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a washing process before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
